Undead Invasion

Undead Invasion rises into TD shooting view as the shattered outskirts pull survivors back toward the once-quiet orphanage. Yet the familiar courtyard now feels different, shaped by ruins, broken fences, and distant shuffling that signals the beginning of another long night. But each return deepens the urgency as undead numbers swell beyond the outer road. The grounds shift from memory to battleground, pushing every decision to carry more weight with each sunset. Begin your stand now!

HOW TO PLAY UNDEAD INVASION

Undead Invasion opens its run with a steady flow built on zombie waves, upgrades, and evolving survival patterns. Yet the flow between Defense and Playground modes highlights two sides of progression: rising pressure under nightly assaults and calmer testing moments with long-term advantages. So the path naturally moves into mission-driven growth that expands the survivor’s reach across the ruined property.

Reinforce worn perimeter zones by rebuilding walls, placing layered defenses, and adapting structure layouts as nightly assaults escalate beyond earlier boundaries.
Gather resources across each encounter to unlock stronger firearms, improved traps, reinforced barriers, and additional tactical upgrades that reshape the battlefield’s flow.
Expand the orphanage grounds by clearing blocked routes, opening new placement areas, and creating expanded lanes that support broader defensive planning over time.
Strengthen late-run survivability through enhanced weapon tiers, optimized trap combinations, upgraded fortifications, and tightly arranged frontline tools that stabilize pressure.
