Deceit

Deceit is a free-to-play social deduction horror game for PC, developed and published by World Makers on CryEngine and released on 4 October 2016. Six players try to survive a night across several locations, but two of them are secretly infected and can turn into monsters. Nobody can tell from the outside who is who, so the innocent four have to read behaviour and find the infected before they are hunted down. A sequel, Deceit 2, followed, and the servers of the original game were shut down on 6 November 2025 (Wikipedia).
