R.E.P.O. has sold approximately 6.7 million copies on Steam in 2026, generating an estimated $44.7 million in revenue, according to market research firm Alinea Analytics. The figures highlight the continued popularity of the co-op horror game, which has established itself as one of the platform’s major indie success stories.
In its October 30, 2026, report, Horror Games Are KILLING It (Literally and Figuratively), Alinea Analytics estimated that R.E.P.O. has sold 28.7 million copies on Steam since launch, generating approximately $213.5 million in lifetime revenue. These figures suggest that the game continues to attract players well beyond its initial release period.
The figures are third-party estimates rather than official sales numbers released by the developer. However, they place R.E.P.O. among the most commercially successful independent horror games on Steam.
Co-Op Horror Continues to Find an Audience
R.E.P.O.’s performance reflects the growing commercial appeal of multiplayer horror games, particularly titles built around cooperative gameplay, unpredictable encounters, and entertaining moments that players can share online.
Unlike traditional single-player horror games that focus primarily on a carefully directed narrative, co-op experiences can generate memorable situations through player interactions. The resulting chaos also makes these games suitable for livestreams and video content, helping them reach audiences beyond their existing player base.
Alinea Analytics identified another major example in Phasmophobia. The ghost-hunting game generated an estimated $28.9 million on Steam in 2026 from 2.1 million copies sold. Its lifetime Steam revenue has reached nearly $270 million, according to the firm’s estimates.
Together, R.E.P.O. and Phasmophobia demonstrate the financial potential of cooperative horror games, even alongside major releases from established franchises.
Alinea Analytics estimates that horror games generated approximately $1.3 billion in Steam revenue during 2026 so far, representing a 17% increase over 2025. Horror accounted for roughly 7% of Steam’s estimated $18.1 billion in total revenue during the same period.
However, major franchises remain important contributors to the genre’s performance. Resident Evil Requiem alone generated an estimated $211.3 million on Steam in 2026, while the Resident Evil franchise collectively accounted for approximately $410 million in horror-game revenue on the platform.
Against this competitive terrain, R.E.P.O.’s estimated $44.7 million in 2026 revenue demonstrates how independent multiplayer games can compete for attention in a market dominated by both established franchises and emerging co-op experiences.
