One of the three Forts in Fort Zombie.
It is a two–story building with one tiny basement and partial roof access through the second–floor library on the left. The building itself has entrances on all four sides. It is surrounded by a large boundary wall, which features several sizable breaks. The top of the outer wall can be reached at the corner building towers — additionally, the rear wall can be accessed via a ramp from the roof of the building.
The Prison is listed as the medium–difficulty Fort. It provides no statistical bonuses to either survivors or zombies.
The initial zombies are spread lightly through the building and especially cluster at the main entrance and in the cell blocks.
