The goal of surviv.io is to be the last player standing. You only live once per game - there is no respawn!
If you've played other battle royale games like PUBG, Fortnite or Apex Legends, then you're already halfway there! Think of surviv.io as 2D PUBG (with slightly less desync and more chicken).
Loot and Kill
You'll begin the game with no items other than a simple backpack. Move around the map to find loot: weapons, ammo, scopes, and medical items. Eliminate other players and you can take their loot!
Red = Bad!
Players aren't the only thing that can hurt you. The deadly red zone will move in from the sides of the map and deal increasingly greater damage if you stand in it. Keep an eye on the map and stay safe.
