Undead Invasion

About Undead Invasion

Undead Invasion is a pixel-style, side-scrolling survival game set after the end of the world. You play a lone survivor holding a strip of ground against wave after wave of the undead, with each new day bringing faster, tougher, and more varied zombies than the last.

The game blends shooting with light defense building. Firearms, melee weapons, grenades, and placeable traps all play a role, and death is permanent: fall once and you start the whole run over from the beginning, which makes every wave genuinely tense.

How to Play Undead Invasion

Move left and right along the battlefield and attack the incoming horde before it reaches you. Zombies strike when they get close, so spacing is everything; kick or swing melee weapons when they press in, and use guns to thin the crowd from range.

Defenses and traps

Between waves you can place barricades and traps to slow the advance. Thoughtful placement buys precious seconds, funneling zombies into your line of fire instead of letting them surround you.

Progression between days

• Zombies drop coins and resources when defeated.
• Spend earnings on new weapons and upgrades before the next wave.
• Prepare for variety; later days mix in faster and stronger zombie types.

Survival tips

• Keep moving; standing still is how you get surrounded.
• Save grenades for dense clusters rather than single targets.
• Rebuild damaged barricades during quiet moments, not mid-swarm.
