How to Play Undead Invasion
Build, Fight, Adapt
Undead Invasion gameplay follows a strategic loop:
- Gather resources -> Purchase weapons/build fortifications -> Repel waves -> Repair damage and upgrade.
Shotguns must be prioritized for close-range crowd control. Try to aim for the head to achieve quick kills.
Automatic sentries are not recommended; this is because they perform poorly in combat. You could take direct control of the battlefield instead. When resources allow, the Juggernaut or Hazmat suit will improve your survivability significantly.
Melee Weapon Priority. Try to obtain the Marasuma Blade or Grate Sword early. These weapons could slice through multiple zombies with one strike and prove extremely effective at close range.
Survival Tips. The Spacebar must be used to create distance when reloading. Speed and strength upgrades should always be your priority.
Control Guide
- Mouse: Aim, build fortifications (select the fence icon).
- Q Key: Switch weapons.
- E Key: Use dagger.
- R Key: Reload.
- Space Key: Kick to push back zombies.
- Numpad 1: Use bombs.

Undead Invasion: This game focuses on tactical depth and construction freedom. You could place various traps and obstacles across different terrain layers. The massive weapon arsenal allows you to create your own fortress. Roguelike elements ensure each playthrough brings new surprises.
Undead Corridor: This title emphasizes fast-paced shooting and agile movement within a fixed corridor. Gameplay is more straightforward with fewer static fortifications. Player dodging skills and accurate shooting are the primary focus.
