Band of Defenders is a modern online CO-OP FPS game where up to four players protect one central object against masses of savages and mutants who rule the world, which is slowly recovering from nuclear apocalypse. Players build, repair and upgrade barricades and turrets, craft weapons and try to survive waves of enemies.

Each game consists of a few waves of enemies and the players have time to build their defenses after they deal with each wave. The last wave is always lead by one of the enemy bosses, highly dangerous individuals that will test your defenses and skills to the fullest.
