How to Play Undead Invasion

In Undead Invasion, the core gameplay centers on holding ground against escalating waves while juggling upgrades, barricades, and resource spending. Every zombie push grows fiercer, creating a flow of defense, repair, and adaptation that shapes your long-term survival. Before each wave or in between waves, you can place barricades, drop traps, and more to slow down zombies, giving your character more time to fight back. Move left and right, attack with your chosen weapons, and keep distance from the undead. They will attack you when you get too close, so kick your foot and use melee weapons if enemies get too close. You can also throw grenades to eliminate large clusters. You earn coins by defeating zombies and surviving the full day. Use that money to purchase stronger weapons, health items, and additional defense items for surviving harder waves ahead. If your character dies in Undead Invasion, you have to start from the very beginning, since there are no checkpoints.
