Undead Invasion — Defend the Orphanage. Survive the Onslaught

A grim roguelike shooter meets tower defense

Undead Invasion throws you into a collapsing homeland — a ruined orphanage that becomes your last stand. Each run fuses side-scrolling shooting action with roguelike replayability and tower-defense strategy. Expect tension at every turn: limited resources, randomized upgrades, and evolving zombie threats keep each wave unpredictable.

Gameplay: Defeat, Survive, and Defend

  • Wave-based defense under pressure: Face escalating zombie waves that demand careful planning. Buy resources, build barricades, lay traps, and fortify every defense layer.
  • Experiment and strategize in Playground Mode: Unlock weapons, traps, and upgrades — then mix and match freely to test tactics without risking failure.
  • Constant evolution: New zombie types, tougher waves, and varied weapon options ensure each run plays out differently. Adaptation is key.

How to Controls

  • WASD/Arrow keys - move
  • Mouse - shoot
  • Q - switch weapons
  • E - knife
  • Spacebar - kick
  • R - reload
  • 1 - use items (like bomb or something else)

Use melee or bombs, reload, kick — every action counts when the undead surge.

Victory comes from smart positioning, steady upgrades, and decisive action. Fail once your defenses break — and watch the orphanage and all hope crumble.

Why you should play

  • Strategic variety: Extensive trap and barricade options add tactical depth beyond mere shooting.
  • Replay value: Random upgrades and weapon unlocks guarantee fresh experiences run after run.
  • Rising tension: Every wave gets harder — forcing you to adapt or perish.
  • Creative freedom: Playground Mode lets you experiment freely, discovering new builds before committing them in real runs.

Are you ready to hold the line? Lock the doors. Load your weapons. Defend what remains.

Play Undead Invasion today — and see how long you survive the undead invasion.
