R.E.P.O.: The Swedish Co-op Horror Game Where Breaking a Vase Is the Scariest Thing
Six tiny robots, one very expensive vase and a monster around the corner. How semiwork's physics-driven early access hit out-earned almost everything on Steam, and why it still has players screaming in 2026.
Picture the scene. You and five friends are tiny robots in a dark mansion. Between you, you are carrying a priceless vase down a staircase. Somebody bumps a wall. The vase cracks, its value drops, and in the distance something heavy starts walking towards the noise. Everyone screams at once.
That is a normal minute in R.E.P.O., the co-op horror game from Swedish studio semiwork. It entered Steam early access on 26 February 2025 for Windows at $9.99, and within weeks it was one of the biggest stories on the platform. Between 11 and 18 March 2025 it was Steam's highest-grossing paid game, second in overall revenue only to Counter-Strike 2.
How R.E.P.O. works
Up to six players take control of small robots called Semibots. Each run sends you into a randomly assembled level, built from modular pieces so no two layouts are the same, with a quota to fill. Your job is to find valuables and haul them to extraction points, where they turn into in-game money called SURPLUS.
The twist is physics. Objects are moved with a physics-based grabbing tool, so carrying something heavy or fragile is an act of teamwork and delicate steering. Damaged items lose value, which means every bump, drop and collision costs you. And because hostile monsters roam the levels, the quiet, careful work of moving fragile treasure is constantly interrupted by panic.
Between levels you visit a Service Station to spend your earnings on permanent upgrades, weapons, explosives, tools and supplies. Then you go back in, a little stronger and a little greedier.
Why your voice is your best weapon
R.E.P.O. uses proximity voice chat, meaning you can only hear teammates who are near you in the game world, and their voices get quieter with distance. It sounds like a small detail. It is actually the heart of the game.
Planning a route through a mansion, warning a friend about a monster, arguing over who dropped the television: all of it happens out loud, through voices that fade as people wander off. A shout across the map might not reach anyone. A whisper in the wrong room might attract the wrong listener. The designers made verbal coordination central to success, and that is also what makes R.E.P.O. such entertaining viewing for streams and videos.
The co-op horror family tree
R.E.P.O. belongs to a recent family of cheap, funny, scary co-op games built for friend groups and streamers. Its most famous ancestor is Lethal Company (read our story), the 2023 hit about scavenging scrap for a heartless corporation. Our game database even groups the two together.
The shared formula is clear: a low price, a simple goal, rising quotas, proximity chat and monsters that make communication break down at the worst moment. R.E.P.O.'s contribution is the physics. In Lethal Company, loot is something you carry. In R.E.P.O., loot is something you have to protect, which turns every room into a comedy of fragile objects.
The same wave also lifted PEAK, the 2025 climbing game born in a Seoul game jam (read our feature). Each game proves the same point: your friends are the content.
Awards and status
R.E.P.O. won Best Early Access Game at the Golden Joystick Awards on 20 November 2025. On Steam, it holds an "Overwhelmingly Positive" rating, with 96% of more than 140,000 English-language reviews recommending it.
It is still in early access, which means the developers are continuing to add and adjust content before a full release. No date for that full release has been announced, and the game remains Windows-only for now. For Korean players, the Steam version supports Korean in its interface and subtitles.
Why it matters
WGC's take: R.E.P.O. shows how much life is left in the "friends-plus-monsters" formula when someone adds a genuinely new mechanic. Physics turns a looting game into a slapstick routine, and proximity chat turns that routine into stories people want to share. For small studios, it is another proof that a focused, affordable co-op game can compete with the biggest names on Steam, at least for a few glorious weeks, and often for much longer.
R.E.P.O. is available in early access on Steam for Windows. For more co-op mayhem, read about Lethal Company (here) and the ghost-hunting veteran Phasmophobia (here).
