R.E.P.O. (acronym of Retrieve, Extract and Profit Operation) is an online cooperativesurvival horrorvideo game developed and published by Swedish game studio Semiwork for Windows. It was released in early access on February 26th, 2025 on Steam. It is developed in the Unity game engine using Photon for networking.[1]
R.E.P.O. gameplay is similar to Lethal Company.[2] The game can host up to six players and tasks them with finding valuable items and objects. The players must handle the objects carefully and avoid breaking or damaging them which lowers their value, all while bringing the objects to extraction points to receive in-game money called "SURPLUS".[3]
The game adheres to a roguelike format, employing randomized modular layouts to create unique map configurations for each playthrough. These environments exhibit variations in room arrangement, item placement, and enemy distribution. On each level, you are required to fill each quota at each extraction point before escaping to the truck, and you are incentivized to take more valuables to spend more, but risk transporting and managing your valuables and enemy interaction. Between levels, you visit a "Service Station" which allows the players to spend their SURPLUS on permanent upgrades, weapons, explosives, various tools, and resources like health and energy for the aforementioned weapons and tools. At its core, R.E.P.O. prioritizes verbal cooperation and coordination and strategic planning.[4][5]
