Undead Invasion pulls you into a brutal fight for survival. Master every weapon and tactic to outlast the rising undead threat.

Undead Invasion (So Terrifying!)

Watch out, zombies are coming! Undead Invasion is a side-scrolling shooter where roguelike replayability blends with tower defense planning in a crumbling homeland. Get lost in a land full of zombies, approaching you with terrifying states. It's scary to see them coming closer, feeling like running away!

Coordinate Smoothly: Don't Let The Zombies Get Close!

Use everything you have to coordinate smoothly so that the zombies don't get too close to you. For example, when using a gun, the amount of bullets is limited, when you run out of bullets, you need to take some time to change. So, in case the zombies get too close and you run out of bullets, what should you do? You can choose to switch to a close-range weapon like a knife or kick your opponent away to have time to prepare bullets, or you can also use other weapons with enough wow.
