DayZ

DayZ is an open-world survival game set in a post-apocalyptic landscape crawling with infected. You'll scavenge for food, water, weapons, and medical supplies while managing hunger, thirst, injury, and disease. Death is permanent—lose your gear, start over. Other players are the wildcard: they might trade peacefully, form temporary alliances, or shoot you for your backpack. No safe zones, no respawn timers that matter, no hand-holding. The map is large enough that you can go hours without seeing anyone, then suddenly everything changes. Expect long stretches of tense quiet interrupted by moments of panic. If you want a survival game that doesn't forgive mistakes and treats other humans as the real threat, this delivers.
