Game Information
Description
Undead Invasion is a free online zombie survival game that blends tower defense, side-scrolling shooting, and roguelike upgrades into one tense fight for your life. You are the last defender of a ruined orphanage, and every new day brings a bigger, nastier wave of the undead determined to tear it down.
The loop is all about balance. You gun down approaching zombies from range, kick and melee when they crowd too close, and lob grenades to wipe out clusters before they break through. Between waves you spend your hard-earned coins on stronger weapons, repairs, and extra barricades and traps, placing them so the horde funnels exactly where you want it. Because every run is randomised and there are no checkpoints, each session plays out differently, and one careless decision can cost you the entire attempt.
Perfect for players who love tactical defense, survival challenge, and roguelike progression, Undead Invasion runs instantly in any modern browser on desktop or mobile with no download. Build your fortress, hold the line, and see how many days you can last. Play Undead Invasion free on MiniPlay.
How to Play
How to Play Undead Invasion
1. Defend the orphanage - your base is your only lifeline. If it falls, the run is over, so protect it at all costs.
2. Aim and shoot - use the mouse to aim and click to fire, keeping zombies at a distance with ranged weapons whenever you can.
3. Aim for the head - headshots drop zombies far faster, so track the head as they shamble toward your walls.
4. Kick when they close in - press the spacebar to kick zombies back when they get too close, buying time to reposition or reload.
5. Use melee as a backup - press E to lash out with your dagger and Q to switch weapons when a zombie is right on top of you.
6. Reload smart - press R to reload, and only do it behind cover or while your barricades hold the line.
7. Build defences - place barricades and traps from the fence icon to slow the horde and channel it into kill zones.
8. Mind your traps - position traps in narrow passages and choke points where many zombies pass through for maximum damage.
9. Throw bombs for clusters - press Numpad 1 to clear tightly packed groups before they overrun your defences.
10. Repair between waves - use the calm moments to fix damaged barricades so they survive the next, heavier assault.
11. Spend your coins wisely - buy stronger weapons, health items, and extra defence, and remember there are no checkpoints.
12. Survive as many days as you can - each new day brings tougher zombies, so keep adapting your build to hold the line.
Build it up, hold it down, and outlast the horde. Play Undead Invasion free on MiniPlay.
