Zombie Towers: Merge TD Defense puts you in charge of humanity’s final stronghold in a world overrun by the undead. This is not a slow or forgiving defense game. Zombies attack in massive, brutal waves, coming from multiple directions at once, and even a single breach can mean total defeat. Your mission is clear: build powerful defenses, manage your resources wisely, and make sure the walls never fall.

At the heart of the gameplay is a clever merge system. You place basic towers to defend entrances, then combine towers of the same level to create stronger versions with heavier weapons and faster firepower. Every merge is a step toward survival, as enemies become tougher and more numerous with each wave. Choosing when and where to merge is just as important as placing towers in the first place.

You are not alone in this fight. Workers can be recruited to carry ammo to your towers and repair damaged walls. Upgrading these workers is essential, because without ammo and repairs, even the strongest towers will eventually fail. You must constantly decide where help is needed most, balancing offense and defense under pressure.

The game also features powerful boosters that can turn the tide when things look hopeless. Use an EMP to freeze zombie swarms, deploy a Nuke to clear the screen, activate Triple X to multiply your damage, or trigger Headshots to make every shot deadly. Timing these abilities correctly can save a run that is seconds away from disaster.

Each run is easy to start but challenging to master. Smart resource management, careful upgrading, and quick reactions are the keys to success. Zombie Towers: Merge TD Defense can be played for quick sessions or long survival streaks, works offline, and constantly pushes you to improve as the zombie hordes grow stronger and more relentless.
