About Undead Invasion
Undead Invasion is a pixel-style side-scrolling zombie survival game. The game was released on December 10, 2025, and mixes shooting, defense, roguelike progression, and resource management into a wave-based survival challenge. You control a lone survivor defending a ruined base while zombies become stronger and more numerous with each passing day. Earn coins from surviving and defeating enemies, then use them to improve weapons, health, barricades, and traps before the next wave arrives.
Gameplay Walkthrough
- Move around and attack: Move left and right while the zombies come toward you. Shoot them when they are at a distance and use melee attacks when they get too close.
- Keep the zombies away: Getting surrounded is where things usually go wrong. Try to leave yourself some room to move instead of letting the whole wave reach you at once.
- Set up defenses: Barricades and traps can slow the zombies down. Put them in useful spots so you have more time to shoot or deal with enemies that get through.
- Throw grenades: When a bunch of zombies are packed together, that is a good time to use a grenade. It can clear some space pretty quickly.
- Survive each day: The waves get tougher as you continue. Some zombies move faster and take more work to kill, so the same setup will not always be enough.
Features That Fuel the Madness
- Zombie waves: There is always another wave coming. Getting through one just means preparing for the next one.
- Different weapons: Use guns when you have some distance and melee weapons when zombies are right in front of you.
- Traps and barricades: These give you some extra time when there are too many zombies to handle normally.
- Gear upgrades: Killing zombies and surviving waves gives you coins. Spend them on weapons, health, and more defenses before things get harder.
- No checkpoints: If the survivor dies, the run starts again. Losing a good run after making it through several days can be pretty rough.
- Pixel-style action: The side-scrolling view keeps things simple. You can see the zombies coming and react without a lot of extra stuff covering the screen.
Tips for New Players
- Keep moving when the wave gets crowded.
- Do not let zombies surround you.
- Use melee attacks when they get too close instead of wasting time trying to shoot at point-blank range.
- Save grenades for groups.
- Place traps where several zombies have to pass through.
- Upgrade your weapons and defenses before the harder days.
- Do not spend all your coins without thinking about the next wave.
- If a run is going well, play a little safer. There are no checkpoints if you die.
