40,000 enemies. One bastion. Hold the line.

Zukontide is an incremental tower defense at swarm scale. The Zukonid tide doesn't file in one lane at a time — it floods the map in the thousands, piles up at your chokepoints in a physical crowd-crush simulation, and claws at your walls while the mass shoves in from behind. Thousands of enemies on screen at once, each one a body with weight — the horde behaves like a horde: it backs up, it crushes forward, it drowns you.

Castellan Harrow is honest in your first briefing: you are expected to fall. Your job is not to survive — your job is to make the tide bleed. Kills bank credits even in defeat, and credits buy persistent research: new weapons, deeper upgrade tracks, heavier bastion armament. Lose, grind, return, and turn the map that broke you into a killing field.

Five sieges escalate from a 650-strong probing assault to a 40,000-strong flood, and the ruined walls that shape each battlefield are also your gun platforms — the swarm breaks against the same stone your turrets stand on.

The War Effort

• A horde with mass — a real crowd simulation, not a conga line. The front rank gnaws your walls while thousands more pile into the choke behind them.
  
• Losing pays — every kill earns credits, victory or defeat. Persistent research between battles, and even mid-battle from the pause menu.
  
• Six weapons, stacking effects — autoguns slow, autocannons knock back and burst the small ones apart, plasma burns. An enemy that's slowed AND burning takes +50% damage from everything.
  
• Artillery that arcs — Big Bomba shells lob clean over the swarm and detonate where they land; the Inferno Bomba leaves craters that keep burning.
  
• Soldiers you command — and sacrifice — a Barracks fields laser troopers you order directly with marquee multi-select. The swarm aggros onto them: fragile, expendable bait — or march them into dormant super-weapons that wake only by consuming one.
  
• Arm the bastion — upgrade your gate from a bare wall to a fortress crowned with four overcharged red plasma corner guns.
  
• Five escalating sieges — 650 to 40,000 enemies, including a bastion assaulted from every side at once and a map where you place the walls yourself.
  
• Battle abilities — call an Orbital Strike into the thickest press, or slam down an Emergency Barricade and let them gnaw through it.
  
• Three ways to fall — Normal, Hard, and Endless. Hard ends with THE ZUKOLORD, a colossal chrome monster that walks over your walls; Endless ramps the pressure until you break, with per-map records.
  
• Know your enemy — Skitterlings, red Rushers, wall-ignoring flyers, armored Zukomaws, chrome Iron Zukonids. A kill-count codex pays bounties for every species you master, and Hard clears earn medals.

The bastion will fall. Make them pay for it.
