Raid Bunker

The raid bunker is North East from the base that has three bridges. The bunker is heavily guarded and requires a bunker key card located inside of the noob's base. There are multiple noobs and they all carry a Beretta's acting the same as a guard. Because there are so many it is recommended to bring the super shield or wear juggernaut armor. Besides the swarm of noobs there is a boss battle being the "Noob SCP-682". With every single money crate within the noob's base and bunker you can earn your self about $1,000,000 which is quite a lot of money within the early rebirths in the game. The bunker has the Uzi and a crate of Super Ammo inside in one of the rooms and one room has a key card to activate the boss battle and reach the vault with $900,000. The rooms spawn randomly within the bunker to make it a little more difficult to find the Uzi and key card.
