About This Demo

Fight for survival in a world overrun by endless zombie hordes. Build your defenses, unlock devastating weapons, and upgrade powerful skills as you battle increasingly dangerous waves of the undead.

As the hordes grow larger and stronger, every upgrade matters. Strengthen your arsenal, adapt your strategy, and see how long you can survive against thousands of relentless zombies.
