SOS is a free-to-play multiplayer survival action game released in 2018 by Outpost Games. Set on La Cuna Island, up to 32 players must survive against both each other and monster hordes while collecting relics. The game features emote-based communication, a reputation system, weapon scarcity, and supply drops. Players describe the experience as tense and intense, with alliances and betrayals driving the social gameplay. The small player count amplifies every interaction, and monster encounters create constant tension throughout each session. Reviewers note that pre-game introductions feel cinematic, and weapons are rare and improvised. The game received a 26% positive rating based on 1045 Steam reviews.

About SOS: In SOS: BR, You are 1 of 32 players on La Cuna Island, forced to fight to the death. Along with your wits, you will have to equip yourself. Guns are certainly an option, but melee weapons are just as deadly. Keep your eyes open for footprints and other indicators that help you stalk your enemies...
