The fifth floor is the gateway from the Dead Zone.
It is also the center of the CTF arena. Whichever team dominates this floor should dominate the game.
All manner of weapons and armor are to be found on this floor
However, there is no ammo or health, so resupply runs to floors four and six will be necessary to hold the floor.
The front (top left) stairwell here has limited access. There's a slit to pop a pineapple through, but it is too narrow for the players. This provides somewhat of a bypass to the chaos on the fifth for prospective flag carriers.
