Undead Siege

Bullet-hell tower defense against the horde. Drag to move, auto-fire, build five turret types, evolve your weapons, and hold your beacon to the last wave.

The horde is coming. Your beacon must survive.

Undead Siege is a top-down bullet-hell tower defense game. Drag anywhere to move, auto-fire at the nearest threat, and hold the line while the dead close in from every side.

CHOOSE YOUR SURVIVOR Three playable characters, each with its own weapon and ability: • Ranger — a steady sidearm and a quick Combat Roll dash. • Gunner — a rapid-fire machine pistol backed by Overclock. • Engineer — starts with a free turret and calls in an Overdrive that supercharges all turrets and repairs them at once. Then set your stakes — Normal, Hard, or Nightmare. A tougher horde pays out a bigger score.

BUILD YOUR DEFENSE Deploy and upgrade five turret types — Sentry, Gatling, Mortar, Cryo, and Tesla — each with its own range, splash damage, freeze, or chain lightning. Repair turrets mid-fight and cycle target priority on the fly.

LEVEL UP, RUN AFTER RUN Cut down walkers, runners, spitters, bloaters, and towering Brutes for XP, then pick from a pool of 18 upgrades every level — fire rate, damage, pierce, regen, turret buffs, orbiting blades, a toxic aura, and more. Stack the right combinations and your weapon EVOLVES — a piercing Railgun, exploding Flak rounds, an overheating Meltdown barrel, a whirling Buzzsaw ring, and more. Every run plays differently.

FACE THE BOSSES Hold long enough and the horde sends something bigger: the Abomination and the Warden, two boss-tier threats with their own attack patterns.

PROGRESS BETWEEN RUNS Earn scrap in-run to build on the spot, and bank coins and diamonds from every run to unlock new turrets, survivor perks, and core specials — cannon bursts, shock novas, energy shields — in the Armory. Permanent progress that carries into your next attempt.

HOLD THE LINE Survive to extraction and call in the win — or waive the rescue and push into overtime for a higher score. Or don't, and go again.
