Undead Siege
Hold a desert town through waves. Every fifth wave adds a mutant boss. Clearing a wave returns some health.

About Undead Siege
Undead Siege drops you into a desert town overrun by the undead — hold your ground and gun down wave after wave before they tear you apart.
Shamblers, armored army zombies, and cops close in from every side, and every 5th wave throws a hulking mutant boss into the mix. Duck behind wrecked cars, rocks, and cactus for cover while you line up your shots.
Clearing a wave patches up some of your health, so staying alive to the end of each one matters. How many waves can you survive, and how high can you push your score?
Undead Siege is a desert-town holdout. Shamblers, armored army zombies, and cops close in; every fifth wave adds a hulking mutant boss. Cover includes wrecked cars, rocks, and cactus.
Clearing a wave restores some health, so finishing the wave is part of the heal. Score and wave count are the chase.
What you do in Undead Siege
Objective. Hold a desert town through waves. Every fifth wave adds a mutant boss. Clearing a wave returns some health.
Move, aim, and hold fire. Use wrecked cars, rocks, and cactus as cover. Shamblers, armored army zombies, and cops close in.
Desktop is WASD plus mouse-hold. Phone is left-half move, right-half aim-and-hold. The middle is not a shoot button. Score is a local survival number.
How to play Undead Siege
On desktop, WASD or arrows move, mouse aims, hold left click to fire. On mobile, left side of the screen moves, right side aims and shoots.
Strafe between cover pieces. Standing in the open during a boss wave is how the run ends even if your aim is fine.
Prioritize the zombies already in melee range, then armored targets, then the boss when it is actually exposed.
Controls
WASD or arrow keys to move, aim with your mouse and hold the left button to fire. On mobile, drag the left side of the screen to move and drag/hold the right side to aim and shoot.
WASD or arrows, mouse aim, hold left button to fire.
On a phone or tablet: Left drag move, right drag-and-hold fire. Portrait is cramped.
What makes Undead Siege different
- Twin-stick holdout, not a tap-to-throw arcade
- Wave-clear heal is the recovery mechanic
- Cover matters more than standing in the open to 'track better'
Tips
- Do not camp one cactus the whole game. Packs spawn from multiple sides.
- Reload your brain after a wave heal: the next spawn may be behind you.
- Boss waves are about not getting surrounded. Kite around a car, do not face-tank in the street.
- If mobile aim feels floaty, use smaller right-thumb motions. Giant swipes overshoot.
Strategy
- Use wrecked cars and cactus as cover. Standing in the open to ‘track better’ is how waves eat you.
- Every fifth wave is a mutant boss. Clearing a wave returns some health — that is the recovery.
- On a phone, left half moves and right half aims. The middle is not a shoot button.

Guides that mention this game
- Undead Siege: cover, waves, and the two-thumb layout — A desert-town wave shooter on Pokii Games: shamblers, armored undead, a mutant every five waves, and a control scheme that feels broken if you treat it like a tap-to-throw arcade.
- Which Pokii Games actually want a keyboard — Most of this catalog is a thumb. A few titles are worse — or simply different — without keys. This is that list, taken from the live builds, not from a “desktop games” keyword.
- A sensible order through the Pokii action shelf — Speed Boat, Cannon Attack, Knife Hit, Crane Stack, Cross Runner, Undead Siege, and Coil Arena use different verbs. This is the order we would give someone who tapped Action and froze.
