Undead Siege: Zombie Survival

New in 2.0 — a 50-world campaign you walk in order. Every world asks for five unbroken minutes before it lets you move on.

They took your family. Fifty worlds stand between you and them.

You are a prince whose spouse and child were abducted. Their captors' portal jumps from world to world, and you follow it on foot — one siege at a time, in order, from the first world to the fiftieth.

A CAMPAIGN YOU WALK IN ORDER Fifty distinct battlefields, each with its own name, terrain, and horde. There is exactly one way to reach the next one: survive a full five minutes without a break. Go down or get overrun, and the world stays yours to retry. Difficulty climbs across five generations, from the opening skirmishes to late worlds that hit nearly three times as hard.

FIGHT FOR YOUR SIGHT LINES Every world lays out its own walls, wreckage, and alien growths. Cover blocks your shots and theirs, reshapes the routes the horde takes, and forces you and every ranged enemy to work for a clear line. Drag anywhere to move; your survivor auto-fires on its own. Set fire priority to nearest when you need breathing room, or to strongest when one big thing has to fall first.

CHOOSE YOUR SURVIVOR • Ranger — a steady sidearm and a quick Combat Roll with brief invulnerability. • Gunner — a rapid-fire machine pistol and Overclock for a burst of raw fire rate. • Engineer — a piercing nailgun, and a beacon that answers to them. Fight close to the core to hit harder, then trigger Core Surge to snap its shield back to full and more than double the pace of its cannon and nova. Then set your stakes — Normal, Hard, or Nightmare. A tougher horde pays out a bigger score.

LEVEL UP INSIDE EVERY RUN Cut down walkers, runners, spitters, bloaters, and towering Brutes for XP, then pick an upgrade at every level — fire rate, damage, pierce, multishot, regen, orbiting blades, a toxic aura, and more. A run can only open eight of the thirteen lines, so what you take is what you become; re-deals let you refuse a bad hand. Max the right pair and your weapon EVOLVES: a piercing Railgun, a detonating Flak Cannon, an overheating Meltdown barrel, a grinding Buzzsaw ring, a life-stealing Reactor Core, or Mag-gloves that pull every drop across the field. Six evolutions, and no two runs stack the same way.

FACE THE BOSSES Hold long enough and the horde sends something bigger: the Abomination and the Warden, two boss-tier threats with their own bullet patterns. Every boss you put down drops 5 diamonds.

BUILD THE CORE THAT KEEPS YOU ALIVE Coins buy permanent survivor perks — health, damage, speed, XP gain, and scrap gain. Diamonds upgrade the beacon itself: hull, self-repair, an energy shield, cannon bursts, and shock novas. Earn diamonds by downing bosses, by finishing runs, from an optional rewarded ad, or buy a pack outright.

AFTER THE FIFTIETH Clear all fifty worlds and the pursuit does not stop. Endless worlds keep generating at full difficulty, and overtime cycles boss after boss for as long as you can hold the line.
