Deadtone

Fortress defense

Deadtone is a PC tower-defense game about holding a fortress during a zombie outbreak. A mysterious sound transmitted through radios and phones turns anyone who hears it into a zombie. Your fortress’s sirens drown out the sound, but they also draw the horde to your walls. You place defenses, watch where attacks hit hardest and send support to keep the fortress standing until each assault ends.

Early operations send a few hundred zombies. Later, an operation can bring hundreds of thousands over the course of the attack. Your turrets fire at the horde beyond the walls, and you decide where each weapon sits and which angles it covers. Turrets, flamethrowers and mortars need to cover one another’s gaps so the approaching zombies meet overlapping fire.
