Zancudo Control Tower

The Zancudo Control Tower is the only enterable building in Fort Zancudo. There is an elevator inside that opens and closes but it does not move between floors. On the top floor, there is a cowardly guard that will act afraid when threatened with any type of weapon. This behavior is unique for military NPCs, who usually are not afraid of the player and will always fight back.

 * UV Map - On the UV Map, there is writing by the tower that says "take control" with an odd symbol next to it, which has spawned many different theories on what it could mean
