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

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.
