Bunkers

Bunkers are underground hideouts in surviv.io, located across the map. There are five types of bunkers in the game: The Hydra Bunker, the Conch Bunker, the Storm Bunker, the Crossing Bunker, 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 in the game. It has multiple entrances and 7 automatic doors, 2 leading into rooms with lockers, as well as the main entrance. This building is home of the Vector. In the changelog, it says its the second largest bunker so we may expect a larger bunker in the future.

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 grey shipping containers on the beach. This is the third sea themed building, the other two being the docks and the hut. It's almost as big as the Storm Bunker.

Storm Bunker
The Storm Bunker is a medium-sized bunker hidden in a shack. It rare to find and disguised. You can find a hatchet case or a weapons chest in the control room, as well as a Bunker Crate. The entrance of the bunker was designed by Firehoax.

It has a 90% chance for a chest to spawn and a 10% chance for a hatchet case.

Egg Bunker
The Egg Bunker, aka a regular 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.

Crossing Bunker
The Crossing Bunker is the second largest bunker in the game. It is one of the few buildings that may not spawn in the game. It can only be found in big rivers by locating a gray square on the map. It has four entrances and a locker exclusive to the bunker. It also contains a control panel that opens up a small storage area which gives you a wood axe to clear the way for the fourth entrance.

Strategies

 * if you run into the door while it’s closed, items and players will show up before the ceiling shows up. Same for when you back away far enough, the ceiling will vanish before the players and items do. So if you are afraid someone will be waiting for you with a shotgun, run into the door and back up until the ceiling disappears, then repeat. If you do it fast enough, you will see what’s inside the bunker door. May take some practice. Only works for nonautomatic doors.
 * Inside the bunker combat is messy, the best weapons are high fire rate and spray ‘n pray weapons like the dual G18C, MAC-10, Vector, M416, etc.
 * If you are missing a weapon, try locating an Egg Bunker. They are very easy to find and are usually not looted.
