Defending a besieged fortress from aboard a heavy attack aircraft puts you in charge of perimeter defense in the air shooter Gunship: Zombie Siege. Switch thermal imager modes, aim rapid-fire cannons, grenade launchers and large-caliber artillery at crowds of zombies, and between attacks, repair walls and upgrade weapons with the money you earn. Launch guided missiles, call in mortar support, plant decoys to distract the undead, and survive a fortress siege in Gunship: Zombie Siege.
