ZombieMod takes a unique approach on the Zombie Apocalypse by putting it in the perspective of a military commander, not a survivor. Since it is 2 years after the first infections, resistance on the east coast is organized, resulting in battles rather than small groups fighting for survival.
The Radio Tower allows the Survivors to excel in the later phases of the battle. Through the Radio Tower, doctrine specific support squads can be requisitioned. Furthermore, the Radio Tower reduces ability recharge times, and boosts Survivor combat performance. The Radio Tower also increases units' sight packages, and provides a large sight radius. The Radio Tower can hold several squads for defense.
