Undead Invasion

Undead Invasion is a side-scrolling shooting game where roguelike replayability merges with tower-defense planning inside a collapsing homeland. Set in a ruined orphanage, this in-game place becomes your headquarters, guiding your every decision with rising tension and limited resources. Randomized upgrades keep each run unpredictable, while expanding weapon options elevate every wave into a tougher stand. The harsh road awaits—step in and defend what remains!

GAMEPLAY: DEFEAT, SURVIVE, AND DEFEND

Core rules in Undead Invasion center on holding ground against escalating waves while juggling upgrades, barricades, and resource spending. Every zombie push grows fiercer, creating a flow of defense, repair, and adaptation that shapes your long-term survival.

• Defense: Wave-based survival path with resource buying, barricade building, and escalating zombie pressure forcing strategic placements across every defense layer.
• Playground: Creative space using unlocked items freely, enabling experimentation with traps, weapons, and layouts without death risks interrupting your tactical testing.

Then, you need to lean on expanding your weapon collection, reinforce structures, and select upgrades that dictate each run’s pace. Resource gains fuel your purchases, while daily waves add difficulty as new zombie types appear. So, you need to boost your weapons’ power and adapt to various types of them to conquer all undead waves. Victory grows from smart positioning and steady improvement, while failure arrives once your defenses collapse and the orphanage falls.
