Undead Invasion

About Undead Invasion

Undead Invasion is a free pixel-style zombie shooter you can play in your browser, where you defend against waves of undead. You control a lone survivor in a side-scrolling battle. The goal is simple: stay alive through as many days as you can while the hordes get tougher.

You can play Undead Invasion online with nothing to download. Each day you shoot, kick and swing melee weapons at approaching zombies, then spend the coins you earn on better weapons, health items and defenses. Barricades and traps give you room to breathe, but only if you place them well.

There are no checkpoints, so one death sends you back to the start. That makes every wave a real decision about distance, ammo and gear. The game includes gory effects, so it may not suit younger players or anyone who dislikes that kind of content. The Undead Invasion tips below will help you last longer.

Tips to get better at Undead Invasion

Back away while you shoot. Zombies only damage you up close, so every step of distance is free safety.
Save grenades for tight clusters instead of single enemies to get the most from each one.
Set up barricades and traps before a wave starts. Placement matters, so put them where zombies must pass before they reach you.
Spend coins on defense items as well as weapons. Extra traps and barricades matter more as the days get harder.
Keep a melee weapon or your kick ready as a last resort when a zombie slips through.
