Rust

Rust is a multiplayer survival game where staying alive is the only goal. You start naked on an island with nothing, gathering resources to craft tools, build shelters, and defend yourself. Wildlife attacks. Other players raid your base, steal your gear, or kill you on sight. Hunger and cold are constant threats. There's no story, no safe zones, no respawning with your stuff intact. You'll chop trees, mine rocks, hunt animals, and research better equipment through a tech tree. Forming alliances helps, but trust is risky since anyone can betray you. Servers wipe periodically, resetting everyone to zero. Death means losing everything you're carrying. It's harsh, unforgiving, and built around player conflict as much as environmental danger.
