The Sentinel Base Camp is an outpost located in Avant Gardens. It was established by the Sentinels as a safe point, utilizing debris from the destroyed road. Players enter through a hole in the wall at the front of the camp. A trashed bus is suspended above the hole, serving as a door. When players are far away from the bus, it lowers to block Stromlings from getting in. During this time, they appear to swarm the gate, pushing feebly against it.
