About This Game

Overrun the city. Hold the last camp.

On one side, a growing zombie horde. On the other, ten survivors who cannot afford another loss. Zombie Siege is a top-down strategy game combining incremental growth, camp tower defense, and tactical drafting. Three modes have separate saves: spread the outbreak, protect the last ten survivors, or choose a side and build your army round by round in Siege Duel.

Siege Duel

Will you defend the city, or tear it down? Choose humans and build firepower, control, and support around the central base. Choose zombies and place nests on the city's outer ring to send a horde in from every direction. Before each battle, make five choices from offers of three cards to gain new buildings or upgrade existing ones. Adjust their positions, lock your lineup, and watch it fight automatically.

Keep up to 12 buildings, with their positions and upgrades carrying into the next round. Nests produce zombies during the first 20 seconds of battle, then stop reinforcing. Plan for both the initial assault and the fight that follows. Inspect weapon ranges and support areas during preparation, and watch combat at 1x, 2x, or 4x speed.

A run lasts 12 rounds. Siege Duel is still being refined and currently uses bot mirror opponents clearly labelled in the interface.

Outbreak

One deployment starts the chain reaction. Pick a spot, deploy your zombies, and use pheromone beacons to focus the horde. Kills earn Flesh, Brains, and Mutagen. Invest them in unit evolution, hive production, and equipment to make your next push stronger.

Quarantine walls seal the east, west, and south. The city keeps stretching north, from slums through downtown and industrial blocks into military zones. Police, SWAT teams, armored units, and giant enemies stand in your way. Advance your horde into tougher districts and rack up kills to break through combat zones.

Seven unit types. Five slots in your army. Shamblers, Runners, Boomers, Spitters, and Abominations fill different roles. Boneguards absorb ballistic damage for nearby allies, while Howlers rally the horde with movement and attack boosts. After clearing your first combat zone, choose your next five-type lineup during Bio-Rebirth: keep the Shambler, select four other types, then incubate them as your new run develops.

Build hives that generate resources and reinforcements, unlock advanced mutations, and strengthen your army through equipment affixes and repeated rebirths. Grow your horde capacity from 500 to 1,000 and try a different approach on your next run.

Last Stand

Command the other side of the siege. Ten survivors gather at the center of your camp. Place walls, towers, traps, and support facilities on a grid as zombies approach from every direction. Survivors who die cannot return during that battle. Lose the last one, and the mission ends.

Choose a loadout of up to six from 23 unlockable facilities and tools. Arrow towers, machine guns, frost towers, Tesla towers, mines, shields, and orbital weapons offer different combinations of firepower, control, and support. Upgrade facilities through four levels to unlock their dedicated upgrade cards. When you level up in battle, the action pauses for a choice of three cards drawn from your loadout's upgrades and shared bonuses.

Fight through 20 campaign missions, each with five waves and a Doom Siegebrute in the final wave. Watch for its telegraphed smash, reinforcements, and low-health frenzy. Defeat the boss and clear the horde to win. Beyond the campaign, tackle endless missions and invest in three ongoing research paths: firepower, fortifications, and logistics.
