Bunkers

Bunkers are underground hideouts in surviv.io, located across the map. There are four types of bunkers in the game, usually one spawning each round: The Hydra Bunker, the Conch Bunker, the Storm Shelter, and the Egg Bunker. The bunkers are all made out of metal, meaning bullets can bounce off their walls, making them highly dangerous to fight in.

Hydra Bunker
The Hydra Bunker is both the largest bunker and the largest building in the game. It has multiple entrances and 7 automatic doors, 2 leading into rooms with lockers, as well as a main entrance. This building is home of the Vector.

Conch Bunker
The Conch Bunker is a bunker submerged in the sea. It was added in the recent "Sun's Out, Guns Out" update. The entrances are in two shipping containers on the beach. This is the second sea themed building, the other being the docks. It's almost as big as the Hydra Bunker.

Storm Shelter
The Storm Shelter is a medium-sized bunker hidden in a shack. It rare to find and disguised. You can find a hatchet case and chest in the control room.

Egg Bunker
The Egg Bunker is a secret underground room, with the entrance hidden under a triangle of trees. It consists of a small metal room containing a barrel and a bunker crate. While the actual bunker is underground and does not appear on the minimap, it can be found by searching the map for a triangle of large, equally spaced trees.
