Unreal Engine is a game engine developed by Epic Games, first showcased in the 1998 first-person shooter game Unreal . Initially developed for PC first-person shooters, it has since been used in a variety of genres of three-dimensional (3D) games and has seen adoption by other industries, most notably the film and television industry. Written in C++, the Unreal Engine features a high degree of portability, supporting a wide range of desktop, mobile, console and virtual reality platforms.
The latest generation is Unreal Engine 4, which was launched in 2014 under a subscription model. Since 2015, it can be downloaded for free, with its source code available on a GitHub private repository. Epic allows for its use in commercial products based on a royalty model, typically asking developers for 5% of revenues from sales, though with the success of Fortnite , which has become a testbed for Unreal Engine for Epic, Epic waives this fee for developers that publish their games through the Epic Games Store. On May 13, 2020, Epic announced that their portion of royalties for games developed in Unreal Engine are waived until developers have earned their first US$1 million in revenue, retroactively applying to January 1, 2020. Unreal Engine 5 is scheduled for full release in early 2022.
It is popular among PC and console games with high graphics capabilities and is used for numerous games, as well as finding further use in filmmaking and other business applications.
The first-generation Unreal Engine was developed by Tim Sweeney, the founder of Epic Games.Having created editing tools for the shareware games ZZT (1991) and Jill of the Jungle (1992), Sweeney began writing the engine in 1995 for the production of a game that would later become a first-person shooter known as Unreal . After years in development, it debuted with the game's release in 1998, although MicroProse and Legend Entertainment had access to the technology much earlier, licensing it in 1996. According to an interview, Sweeney wrote 90 percent of the code in the engine, including the graphics, tools, and networking.
At first, the engine relied completely on software rendering, meaning the graphics calculations were handled by the CPU.However, over time, it was able to take advantage of the capabilities provided by graphics cards, focusing on the Glide API, specially designed for 3dfx accelerators. While supported, OpenGL and Direct3D reported a slower performance compared to Glide due to their deficiency in texture management at the time. Sweeney heavily criticized OpenGL drivers in particular, describing them as "extremely problematic, buggy, and untested", and labeled the code in the implementation as "scary" as opposed to the simpler and cleaner support for Direct3D. With regard to audio, Epic employed the Galaxy Sound System, a software programmed in assembly language that integrated both EAX and Aureal technologies, and allowed the use of tracker music, which gave level designers flexibility in how the soundtrack was played at a specific point. Sweeney stated that the hardest part of the engine to program was the renderer, as he had to rewrite it several times during development, though he found less "glamorous" the infrastructure connecting all the subsystems. Despite requiring a significant personal effort, he said the engine was his favorite project at Epic, adding: "Writing the first Unreal Engine was a 3.5-year, breadth-first tour of hundreds of unique topics in software and was incredibly enlightening."
Among its features were collision detection, colored lighting, and a limited form of texture filtering.The engine also integrated a level editor, UnrealEd, that had support for real-time constructive solid geometry operations as early as 1996, allowing mappers to change the level layout on the fly. Even though Unreal was designed to compete with id Software (developer of Doom and Quake ), co-founder John Carmack complimented the game for the use of 16-bit color and remarked its implementation of visual effects such as volumetric fog. "I doubt any important game will be designed with 8-bit color in mind from now on. Unreal has done an important thing in pushing toward direct color, and this gives the artists a lot more freedom," he said in an article written by Geoff Keighley for GameSpot . "Light blooms [the spheres of light], fog volumes, and composite skies were steps I was planning on taking, but Epic got there first with Unreal," he said, adding: "The Unreal engine has raised the bar on what action gamers expect from future products. The visual effects first seen in the game will become expected from future games."
Unreal was noted for its graphical innovations, but Sweeney recognized in a 1999 interview with Eurogamer that many aspects of the game were unpolished, citing complaints about its high system requirements and online gameplay issues.Epic addressed these points during the development of Unreal Tournament by incorporating several enhancements in the engine intended to optimize performance on low-end machines and improve the networking code, while also refining the artificial intelligence for bots to display coordination in team-based environments. The game also came with increased image quality with the support for the S3TC compression algorithm, allowing for 24-bit high resolution textures without compromising performance. In addition to being available on Microsoft Windows, Linux, Mac and Unix, the engine was ported through Unreal Tournament to the PlayStation 2 and, with the help of Secret Level, to the Dreamcast.
By late 1999, The New York Times indicated that there had been sixteen external projects using Epic's technology, including Deus Ex , The Wheel of Time , and Duke Nukem Forever ,the latter of which was originally based on the Quake II engine. Unlike id Software, whose engine business only offered the source code, Epic provided support for licensees and met with them to discuss improvements to its game development system. While it cost around $3 million to produce and licenses for up to $350,000, Epic gave players the ability to modify its games with the incorporation of UnrealEd and a scripting language called UnrealScript, sparking a community of enthusiasts around a game engine built to be extensible over multiple generations of games.
The big goal with the Unreal technology all long was to build up a base of code that could be extended and improved through many generations of games. Meeting that goal required keeping the technology quite general-purpose, writing clean code, and designing the engine to be very extensible. The early plans to design an extensible multi-generational engine happened to give us a great advantage in licensing the technology as it reached completion. After we did a couple of licensing deals, we realised it was a legitimate business. Since then, it has become a major component of our strategy.— Sweeney, Maximum PC , 1998
In October 1998, IGN reported, based on an interview with affiliate Voodoo Extreme, that Sweeney was doing research for his next-generation engine.With development starting a year later, the second version made its debut in 2002 with America's Army , a free multiplayer shooter developed by the U.S. Army as a recruitment device. Soon after, Epic would release Unreal Championship on the Xbox, with it being one of the first games to utilize Microsoft's Xbox Live.
Though based on its predecessor, this generation saw a notable advance in rendering terms as well as new improvements to the tool set.Capable of running levels nearly 100 times more detailed than those found in Unreal, the engine integrated a variety of features, including a cinematic editing tool, particle systems, export plug-ins for 3D Studio Max and Maya, and a skeletal animation system first showcased in the PlayStation 2 version of Unreal Tournament. In addition, the user interface for UnrealEd was rewritten in C++ using the wxWidgets toolkit, which Sweeney said was the "best thing available" at the time.
Physical simulations, such as ragdoll player collisions and arbitrary rigid body dynamics, were powered by the Karma physics engine.With Unreal Tournament 2004 , vehicle-based gameplay was successfully implemented, enabling large-scale combat. While Unreal Tournament 2003 had support for vehicle physics through the Karma engine, as demonstrated by a testmap with a "hastily-constructed vehicle", it wasn't until Psyonix created a modification out of Epic's base code that the game received fully coded vehicles. Impressed by their efforts, Epic decided to include it in its successor as a new game mode under the name Onslaught by hiring Psyonix as a contractor. Psyonix would later develop Rocket League before being acquired by Epic in 2019.
A specialized version of UE2 called UE2X was designed for Unreal Championship 2: The Liandri Conflict on the original Xbox platform, featuring optimizations specific to that console.In March 2011, Ubisoft Montreal revealed that UE2 was successfully running on the Nintendo 3DS via Tom Clancy's Splinter Cell 3D . "The 3DS is powerful, and we are able to run the Unreal Engine on this console, which is pretty impressive for a handheld machine, and the 3D doesn't affect the performance (thanks to my amazing programmers)," said Ubisoft.
Screenshots of Unreal Engine 3 were presented by July 2004, at which point the engine had already been in development for over 18 months.The engine was based on the first-generation, but contained new features. "The basic architectural decisions visible to programmers of an object-oriented design, a data-driven scripting approach, and a fairly modular approach to subsystems still remain [from Unreal Engine 1]. But the parts of the game that are really visible to gamers –the renderer, the physics system, the sound system, and the tools– are all visibly new and dramatically more powerful," said Sweeney. Unlike Unreal Engine 2, which still supported a fixed-function pipeline, Unreal Engine 3 was designed to take advantage of fully programmable shader hardware. All lighting and shadowing calculations were done per-pixel, instead of per-vertex. On the rendering side, Unreal Engine 3 provided support for a gamma-correct high-dynamic range renderer. The first games released using Unreal Engine 3 were Gears of War for Xbox 360, and RoboBlitz for Windows, which were both released on November 7, 2006.
Initially, Unreal Engine 3 only supported Windows, PlayStation 3, and Xbox 360 platforms, while iOS (first demonstrated with Epic Citadel) and Android were added later in 2010, with Infinity Blade being the first iOS title and Dungeon Defenders the first Android title.In 2011, it was announced that the engine would support Adobe Flash Player 11 through the Stage 3D hardware-accelerated APIs and that it was being used in two Wii U games, Batman: Arkham City and Aliens: Colonial Marines . In 2013, Epic teamed-up with Mozilla to bring Unreal Engine 3 to the web; using the asm.js sublanguage and Emscripten compiler, they were able to port the engine in four days.
Throughout the lifetime of UE3, significant updates were incorporated,including improved destructible environments, soft body dynamics, large crowd simulation, iOS functionality, Steamworks integration, a real-time global illumination solution, and stereoscopic 3D on Xbox 360 via TriOviz for Games Technology. DirectX 11 support was demonstrated with the Samaritan demo, which was unveiled at the 2011 Game Developers Conference and built by Epic Games in a close partnership with Nvidia, with engineers working around the country to push real-time graphics to a new high point.
While Unreal Engine 3 was quite open for modders to work with, the ability to publish and sell games meant using UE3 was restricted to licenses of the engine. However, in November 2009, Epic released a free version of UE3's SDK, called the Unreal Development Kit (UDK), that is available to the general public.
In December 2010, the kit was updated to include support for creating iOS games and apps.OS X compatibility followed in the September 2011 release.
In August 2005, Mark Rein, the vice-president of Epic Games, revealed that Unreal Engine 4 had been in development for two years."People don't realise this but we're already two years into development of Unreal Engine 4. It certainly doesn't have a full team yet, it's just one guy and you can probably guess who that guy is," he told C&VG . Speaking in an interview in early 2008, Sweeney stated that he was basically the only person working on the engine, though he affirmed his research and development department would start to expand later that year, designing the engine in parallel with the efforts by the UE3 team. In February 2012, Rein said "people are going to be shocked later this year when they see Unreal Engine 4"; Epic unveiled UE4 to limited attendees at the 2012 Game Developers Conference, and a video of the engine being demonstrated by technical artist Alan Willard was released to the public on June 7, 2012, via GameTrailers TV.
One of the major features planned for UE4 was real-time global illumination using voxel cone tracing, eliminating pre-computed lighting.However, this feature, called Sparse Voxel Octree Global Illumination (SVOGI) and showcased with the Elemental demo, was replaced with a similar but less computationally expensive algorithm due to performance concerns. UE4 also includes the new "Blueprints" visual scripting system (a successor to UE3's "Kismet" ), which allows for rapid development of game logic without using code, resulting in less of a divide between technical artists, designers, and programmers.
I could say: 'I'm going to convert this pillar into a blueprint [in the Engine] and add some sort of trap to it.' It means I can really go in and start enhancing my world with interaction that just would not have been possible without a technical artist, a designer and a programmer and now any one of those three can do all of it, provided they have the assets handy. The fact that I can just go in and say, 'If you're within X distance of this thing, start to glow and take my distance to it, normalize it zero to one and then just lerp [oscillate] between two different brightness values, so as I reach for something it gets hot'...that would have been something do-able but very difficult for anybody except a gameplay programmer. And he wouldn't have known how to set up the assets, but now any one of the three could do it.— Willard, Kotaku , 2012
On March 19, 2014, at the Game Developers Conference (GDC), Epic Games released Unreal Engine 4 through a new licensing model. For a monthly subscription at US$19, developers were given access to the full version of the engine, including the C++ source code, which could be downloaded via GitHub. Any released product was charged with a 5% royalty of gross revenues. The first game released using Unreal Engine 4 was Daylight , developed with early access to the engine and released on April 29, 2014.
On September 4, 2014, Epic released Unreal Engine 4 to schools and universities for free, including personal copies for students enrolled in accredited video game development, computer science, art, architecture, simulation, and visualization programs.Epic opened an Unreal Engine Marketplace for acquiring game assets. On February 19, 2015, Epic launched Unreal Dev Grants, a $5 million development fund aiming to provide grants to creative projects using Unreal Engine 4.
In March 2015, Epic released Unreal Engine 4, along with all future updates, for free for all users.In exchange, Epic established a selective royalty schedule, asking for 5% of revenue for products that make more than $3,000 per quarter. Sweeney stated that when they moved to the subscription model in 2014, use of Unreal grew by 10 times and through many smaller developers, and believed that they would draw even more uses through this new pricing scheme.
In an attempt to attract Unreal Engine developers, Oculus VR announced in October 2016 that it will pay royalty fees for all Unreal-powered Oculus Rift titles published on their store for up to the first $5 million of gross revenue per game.
To prepare for the release of its free-to-play battle royale mode in Fortnite in September 2017, Epic had to make a number of Unreal Engine modifications that helped it to handle a large number (up to 100) of connections to the same server while still retaining high bandwidth, and to improve the rendering of a large open in-game world. Epic said it would incorporate these changes into future updates of the Unreal Engine.
With the opening of the Epic Games Store in December 2018, Epic will not charge the 5% revenue fee on games that use the Unreal Engine and released through the Epic Games Stores, absorbing that cost as part of the base 12% cut Epic is taking to cover other costs.
Effective May 13, 2020, and retroactive to January 1, 2020, the royalty exemption amount is increased to US$1,000,000 in lifetime gross revenue per title.
The engine officially supports the following platforms as of 4.26:
It formerly officially supported Google Daydream.
Unreal Engine 5 was revealed on May 13, 2020, supporting all existing systems including the next-generation consoles PlayStation 5 and Xbox Series X/S.Work on the engine started about two years prior to its announcement. It was released in early access on May 26, 2021, with expected full launch in early 2022.
One of its major features is Nanite, an engine that allows for high-detailed photographic source material to be imported into games.The Nanite virtualized geometry technology allows Epic to take advantage of its past acquisition of Quixel, the world's largest photogrammetry library as of 2019. The goal of Unreal Engine 5 was to make it as easy as possible for developers to create detailed game worlds without having to spend excessive time on creating new detailed assets, allowing the engine software to handle these factors. Nanite can import nearly any other pre-existing three-dimension representation of objects and environments, including ZBrush and CAD models, allowing the use of film-quality assets. Nanite automatically handles the levels of detail (LODs) of these imported objects appropriate to the target platform and draw distance, a task that an artist would have had to perform otherwise. Lumen is another component described as a "fully dynamic global illumination solution that immediately reacts to scene and light changes". Lumen eliminates the need for artists and developers to craft a lightmap for a given scene, but instead calculates light reflections and shadows on the fly, thus allowing for real-time behavior of light sources. Additional components include Niagara for fluid and particle dynamics and Chaos for a physics engine.
With potentially tens of billions of polygons present on a single screen at 4k resolution, Epic also developed the Unreal Engine 5 to take advantage of the upcoming high-speed storage solutions with the next-generation console hardware that will use a mix of RAM and custom solid-state drives.Epic had worked closely with Sony in optimizing Unreal Engine 5 for the PlayStation 5, with Epic collaborating with Sony on the console's storage architecture. To demonstrate the ease of creating a detailed world with minimal effort, the May 2020 reveal of the engine showcased a demo called "Lumen in the Land of Nanite" running on a PlayStation 5 that was built mostly by pulling assets from the Quixel library and using the Nanite, Lumen, and other Unreal Engine 5 components to create a photorealistic cave setting that could be explored. Epic affirmed that Unreal Engine 5 would be fully supported on the Xbox Series X as well, but had been focused on the PlayStation 5 during the announcement as a result of their work with Sony in the years prior. Epic plans to use Fortnite as a testbed for Unreal Engine 5 to showcase what the engine can do to the industry, with the game expected to use the engine by mid-2021. Ninja Theory's Senua's Saga: Hellblade II will also be one of the first games to use Unreal Engine 5.
Additional features planned for Unreal Engine 5 come from Epic's acquisitions and partnerships. The MetaHuman Creator is a project based on technology from three companies acquired by Epic, 3Lateral, Cubic Motion, and Quixel, to allow developers to quickly create realistic human characters that can then be exported for use within Unreal.Through partnership with Cesium, Epic plans to offer a free plugin to provide 3D geospatial data for Unreal users, allowing them to recreate any part of the mapped surface of Earth. Epic will include RealityCapture, a product it acquired with its acquisition of Capturing Reality that can generate 3D models of any object from a collection of photographs taken of it from multiple angles, and the various middleware tools offered by RAD Game Tools.
Unreal Engine 5 will retain the current royalty model, with developers returning 5% of gross revenues to Epic Games, though this fee is forgiven for those that release their games on the Epic Games Store. Further, Epic announced alongside Unreal Engine 5 that they will not take any fee from games using any version of Unreal Engine for the first US$1 million in gross revenue, retroactive to January 1, 2020.

UnrealScript (often abbreviated to UScript) was Unreal Engine's native scripting language used for authoring game code and gameplay events before the release of Unreal Engine 4. The language was designed for simple, high-level game programming.The UnrealScript interpreter was programmed by Sweeney, who also created an earlier game scripting language, ZZT-oop.
Similar to Java, UnrealScript was object-oriented without multiple inheritance (classes all inherit from a common Object class), and classes were defined in individual files named for the class they define. Unlike Java, UnrealScript did not have object wrappers for primitive types. Interfaces were only supported in Unreal Engine generation 3 and a few Unreal Engine 2 games. UnrealScript supported operator overloading, but not method overloading, except for optional parameters.
At the 2012 Game Developers Conference, Epic announced that UnrealScript was being removed from Unreal Engine 4 in favor of C++.Visual scripting would be supported by the Blueprints Visual Scripting system, a replacement for the earlier Kismet visual scripting system.
One of the key moments in Unreal Engine 4's development was, we had a series of debates about UnrealScript – the scripting language I'd built that we'd carried through three generations. And what we needed to do to make it competitive in the future. And we kept going through bigger and bigger feature lists of what we needed to do to upgrade it, and who could possibly do the work, and it was getting really, really unwieldy. And there was this massive meeting to try and sort it out, and try to cut things and decide what to keep, and plan and...there was this point where I looked at that and said 'you know, everything you're proposing to add to UnrealScript is already in C++. Why don't we just kill UnrealScript and move to pure C++? You know, maximum performance and maximum debuggability. It gives us all these advantages.'— Sweeney, Gamasutra , 2017
With Unreal Engine 4, Epic opened the Unreal Engine Marketplace in September 2014. The Marketplace is a digital storefront that allows content creators and developers to provide art assets, models, sounds, environments, code snippets, and other features that others could purchase, along with tutorials and other guides. Some content is provided for free by Epic, including previously offered Unreal assets and tutorials.Prior to July 2018, Epic took a 30% share of the sales but due to the success of Unreal and Fortnite Battle Royale , Epic retroactively reduced its take to 12%.
The Unreal Engine was primarily designed to be used as the main game engine in video games. Besides Epic's own games, including Gears of War and Fortnite, the engine is used in a number of high-profile game titles, including PlayerUnknown's Battlegrounds , Final Fantasy VII Remake , Valorant and Yoshi’s Crafted World .
The Unreal Engine has found use in film making to create virtual sets that can track with a camera's motion around actors and objects and be rendered in real time to large LED screens and atmospheric lighting systems. This allows for real-time composition of shots, immediate editing of the virtual sets as needed, and the ability to shoot multiple scenes within a short period by just changing the virtual world behind the actors. The overall appearance was recognized to appear more natural than typical chromakey effects.
Among the productions to use these technologies were the television series The Mandalorian and Westworld . Jon Favreau and Lucasfilm's Industrial Light & Magic division worked with Epic in developing their StageCraft technology for The Mandalorian, based on a similar approach Favreau had used in The Lion King .Favreau then shared this technology approach with Jonathan Nolan and Lisa Joy, the producers for Westworld. The show had already looked at the use of virtual sets before and had some technology established, but integrated the use of Unreal Engine as with StageCraft for its third season.
Orca Studios, a Spanish-based company, has been working with Epic to establish multiple studios for virtual filming similar to the StageCraft approach with Unreal Engine providing the virtual sets, particularly during the COVID-19 pandemic which restricted travel.
In January 2021, Deadline Hollywood announced that Epic was using part of its Epic MegaGrants to back for the first time an animated feature film, Gilgamesh, to be produced fully in Unreal Engine by animation studios Hook Up, DuermeVela and FilmSharks.As part of an extension of its MegaGrants, Epic also funded 45 additional projects since around 2020 for making movies and short films in the Unreal Engine.
Unreal Engine has also been used by non-creative fields due to its availability and feature sets. It has been used as a basis for a virtual reality tool to explore pharmaceutical drug molecules in collaboration with other researchers, as a virtual environment to explore and design new buildings and automobiles, and used for cable news networks to support real-time graphics.
The state of the Unreal Engine came up in Epic's 2020 legal action against Apple Inc. claiming anticompetitive behavior in Apple's iOS App Store. Epic had uploaded a version of Fortnite that violated Apple's App Store allowances. Apple, in response, removed the Fortnite app and later threatened to terminate Epic's developer accounts which would have prevented Epic from updating the Unreal Engine for iOS and macOS.The judge agreed to grant Epic a permanent injunction against Apple to prevent Apple from taking this step, since the judge agreed that would impact numerous third-party developers that rely on the Unreal Engine.
A game engine is a software framework primarily designed for the development of video games, and generally includes relevant libraries and support programs. The "engine" terminology is similar to the term "software engine" used in the software industry.
Legend Entertainment Company was an American developer and publisher of computer games, best known for their complex and distinctive adventure titles throughout the 1990s. The company was founded by Bob Bates and Mike Verdu, both veterans of the interactive fiction studio Infocom that shut down in 1989. Their first games, Timequest and Spellcasting 101: Sorcerers Get All The Girls, both had strong sales which sustained the company. Legend also profited from negotiating licenses to popular book series, allowing them to create notable game adaptations such as Companions of Xanth and Gateway. Legend also earned a reputation for comedic adventures, with numerous awards for Eric the Unready in 1993. As the technology of the game industry changed, Legend continued to expand their game engine to take advantage of higher graphical fidelity, mouse support, and the increased media storage of the compact disc.
Unreal Tournament is a first-person arena shooter video game developed by Epic Games and Digital Extremes. The second installment in the Unreal series, it was first published by GT Interactive in 1999 for Microsoft Windows, and later released on the PlayStation 2 and Dreamcast by Infogrames in 2000 and 2001, respectively. Players compete in a series of matches of various types, with the general aim of out-killing opponents. The PC version supports multiplayer online or over a local area network. Free expansion packs were released, some of which were bundled with a 2000 re-release: Unreal Tournament: Game of the Year Edition.
Epic Games, Inc. is an American video game and software developer and publisher based in Cary, North Carolina.

Fortnite Battle Royale is a free-to-play battle royale video game developed and published by Epic Games. It is a companion game to Fortnite: Save the World, a cooperative survival game with construction elements. It was initially released in early access on September 26, 2017, for Microsoft Windows, macOS, PlayStation 4, and Xbox One, followed by ports for iOS, Android, and Nintendo Switch the following year. Epic dropped the early access label for the game on June 29, 2020. Versions for the PlayStation 5 and Xbox Series X/S were released as launch titles in late 2020.
Fortnite is an online video game developed by Epic Games and released in 2017. It is available in three distinct game mode versions that otherwise share the same general gameplay and game engine: Fortnite: Save the World, a cooperative hybrid-tower defense-shooter-survival game for up to four players to fight off zombie-like creatures and defend objects with traps and fortifications they can build; Fortnite Battle Royale, a free-to-play battle royale game in which up to 100 players fight to be the last person standing; and Fortnite Creative, in which players are given complete freedom to create worlds and battle arenas. Save the World and Battle Royale were released in 2017 as early access titles, while Creative was released on December 6, 2018. While the Save the World and Creative versions have been successful for Epic Games, Fortnite Battle Royale in particular became an overwhelming success and a cultural phenomenon, drawing more than 125 million players in less than a year, earning hundreds of millions of dollars per month, and $9 billion in revenue in its first two years.
The Epic Games Store is a digital video game storefront for Microsoft Windows and macOS, operated by Epic Games. It launched in December 2018 as both a website and a standalone launcher, of which the latter is required to download and play games. The storefront provides a basic catalog, friends list management, matchmaking, and other features. Epic Games has further plans to expand the feature set of the store front but it does not plan to add as many features as other digital distribution platforms, such as discussion boards or user reviews, instead using existing social media platforms to support these.
Epic Games v. Apple is a current lawsuit brought by Epic Games against Apple in August 2020 in the United States District Court for the Northern District of California, related to Apple's practices in the iOS App Store. Epic Games specifically had challenged Apple's restrictions on apps from having other in-app purchasing methods outside of the one offered by the App Store. Epic Games' founder Tim Sweeney had previously challenged the 30% revenue cut that Apple takes on each purchase made in the App Store, and with their game Fortnite, wanted to either bypass Apple or have Apple take less of a cut. Epic implemented changes in Fortnite intentionally on August 13, 2020, to bypass the App Store payment system, prompting Apple to block the game from the App Store and leading to Epic filing its lawsuit. Apple filed a countersuit, asserting Epic purposely breached its terms of contract with Apple to goad it into action, and defended itself from Epic's suit. The trial ran from May 3 to May 24, 2021, with a verdict anticipated later in 2021.
Probably the biggest draw to Unreal was the ability to mod it. Tim Sweeney (Founder of Epic) wrote a simple scripting engine into the game called UnrealScript.
