## What is Undead Siege?

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.

Single-player. No account, no login. Fully playable offline; optional rewarded ads and optional purchases require a connection.

## Version history (last 4 releases)

### 2.0 — 2026-08-07

The pursuit is now a 50-world campaign you walk in order, and a world only opens the next one when you survive a full five uninterrupted minutes on it. Turrets are gone: combat is you, your evolving weapon, and the beacon. Builds now diverge — a run can open eight upgrade lines out of thirteen, so what you pick actually costs you something, and every level-up gives you re-deals to spend on a bad hand. Mag-gloves is now the capstone of the two scavenging lines instead of a card that quietly cancelled them. The Armory has been rebuilt: tracks that promised a hundred levels but finished by level twenty now run to twenty or thirty with the same ceiling, and every coin and diamond the old curve overcharged has been paid back — including the turret perk the last update missed. The Engineer is rebuilt around the core, Threat Mark is now a simple nearest-or-strongest switch, and diamonds drop 5 per boss, 5 per rewarded ad, or come in packs. Also: obstacles you could walk through now block, haptics are gentler, the core no longer buzzes the phone, and the camera sits further back.

### 1.2 — 2026-07-21

New in 1.2: Direct the fight with Threat Mark—select an enemy and focus your fire. Turkish now follows your device language on first launch. We also improved purchase and restore feedback, ad privacy handling, Dynamic Type, VoiceOver labels, touch targets, and small-screen layouts.

### 1.1 — 2026-07-16

New in 1.1 — every survivor now plays to its own signature:

• Ranger — Ricochet: your shots bounce into a second target.
• Gunner — Fan Fire: keep firing and it fans into a shredding cone.
• Engineer — Grid: cluster your turrets and they hit harder together.

Turn spare scrap into instant tactical power — Core Repair, Barrier, and a tap-to-target Airstrike.

Plus a livelier character-select screen. Hold the line.

### 1.0 — 2026-07-13
