Zombie Towers: Merge TD Defense puts you in command of the last human outpost. Zombies don’t come one by one—they hit in brutal waves,from every direction,and they only need one breach to doom the city. Your job is simple: build the right towers,keep ammo flowing,and never let the walls fall.
The twist is the merge: combine same-level towers to unlock more firepower and heavier guns,then stack upgrades to match the growing horde. Recruit workers to carry ammo and repair the walls while you decide where damage is needed most. Unlock and time powerful boosters for clutch saves: EMP to freeze the swarm,Nuke to wipe the screen,Triple X to multiply damage,and Headshots to turn every shot into a finisher.
Each run is quick to learn but hard to master—route your resources,choose upgrades wisely,and watch your defense transform from shaky to unstoppable. Play free,play offline,and keep climbing as the zombies get stronger.
