Undead Invasion

About Undead Invasion

Undead Invasion throws you into a harsh post-apocalyptic world where you play as a lone survivor facing relentless waves of zombies. Each new day grows more intense as the undead multiply and become stronger, faster, and harder to kill. Your goal is simple survive as long as possible. Your strategy, timing, and upgrades will determine whether you stand your ground…or fall to the Undead Invasion.

This pixel-style, side-scrolling zombie survival game combines fast-paced shooting with smart base defense. You’ll fight off constant waves of undead using firearms, melee weapons, grenades, and traps. Kick back nearby zombies when they get too close, keep your distance when you can, and eliminate incoming enemies before they overwhelm your position. The further you progress, the more aggressive and varied the zombie hordes become — and the more you’ll rely on smart planning instead of pure firepower.

There are no checkpoints and no second chances. If your character dies, you start from day one. That makes every upgrade, every well-placed barricade, and every wave cleared feel truly meaningful. Earn coins by surviving the day and defeating zombies, then spend them on stronger weapons, health items, traps, and new defenses. Grenades and traps are especially powerful for clearing large groups and buying yourself precious time.

Between waves, you can place barricades and defensive items to slow the undead and control how they reach you. Thoughtful trap placement can be the difference between survival and defeat. As the Undead Invasion grows, you’ll constantly weigh your decisions: upgrade weapons, strengthen defenses, or stack health items to last just a little longer?

The core loop is addictive fight, survive, upgrade, repeat. And when you finally fall, you’ll want to dive right back in to beat your previous survival streak. The retro-pixel art style gives the game personality, while the zombie combat includes gory effects, making it better suited for older players who don’t mind intense action.

Whether you enjoy zombie shooters, wave survival games, or strategic defense gameplay, Undead Invasion delivers a tense and rewarding challenge right in your browser. Every day survived feels like a victory — and every mistake feels costly.

Are you ready to face endless waves of the undead and prove you can survive longer than anyone else? Jump into Undead Invasion, build your defenses, upgrade your weapons, and see how long you can last against the growing horde today!
