Undead Invasion challenges you to survive waves of zombies, upgrade weapons and defend your collapsing shelter with strategy and fast-paced action.
Step into the world of Undead Invasion, a side-scrolling action game where survival depends on skill, strategy, and quick thinking. Set in a collapsing orphanage turned headquarters, every decision carries weight as waves of zombies grow stronger with each passing day. Roguelike elements and randomized upgrades make every run unpredictable, while a diverse arsenal of weapons and traps keeps gameplay fresh and challenging.
DEFEND YOUR SHELTER
At the heart of Undead Invasion lies tower-defense-inspired combat. Players must hold their ground against escalating zombie waves, strategically placing barricades, turrets, and traps. Resource management is key, earn money from defeated zombies, reinforce structures, and invest in weapon upgrades to survive increasingly difficult encounters.

The game offers an expansive weapon collection and diverse defensive tools, shaping every run. Players can:
