In early February of this year, Killer Inn was released on PC in Steam in early access format. The developer was Tactic Studios, and the publisher was Square Enix.
Killer Inn is positioned as a dynamic asymmetrical PvP shooter in which humans ("lambs") must fight killers ("wolves") and eliminate them. The peak online at the start was 817 players and then began to fall.
Recently, Killer Inn was made temporarily free, which had a certain effect.
This weekend, the online player count of Killer Inn rose from ~50 - 100 players to 461 simultaneous users. Reviews are still mixed: players note problems with servers and balance.
