R.E.P.O.

R.E.P.O. (Retrieve, Extract and Profit Operation) is an online cooperative survival horror game for up to six players, developed by Swedish studio Semiwork using the Unity engine. Players are tasked with locating valuable physics-based objects within procedurally generated environments and carefully transporting them to extraction points without damaging them, all while avoiding hostile creatures. Between levels, players spend earned currency on permanent upgrades, weapons, and tools at a service station. The game emphasizes verbal coordination and strategic planning among teammates. R.E.P.O. takes place in a quiet, post-apocalyptic world where humanity has seemingly vanished. Skeletons remain frozen in ordinary, everyday positions inside untouched structures, hinting at a sudden and mysterious extinction event. In the vacuum left by mankind, players assume the role of "Semibots"—humanoid, pill-shaped retrieval droids equipped with gravity-manipulation tools. The Semibots operate under the strict servitude of the "Taxman," a mysterious, detached Overseer AI that communicates exclusively through a bizarre distortion of emojis—most notably a crying-laughing icon. The Taxman deploys the Semibots into abandoned, ghost-town locations—such as subways, stations, and museums—to forcefully reclaim valuable, physics-based items to satisfy astronomical debt quotas. However, these desolate areas are now fiercely guarded by a terrifying assortment of anomalous monsters and hostile, mutated entities. As the droids extract loot, avoid deadly traps, and harvest the glowing pink "souls" of fallen creatures, environmental storytelling reveals a tragic, underlying narrative about the fall of human civilization and the sadistic machine now playing puppet master with what remains.
