The Core Loop

Two halves of one siege

Every day buys you the night. Gather, build and grow stronger while the sun holds — then the bell rings, and the horde comes for your walls.

☀ Daylight

Build the stronghold

Loot chests, mine ore and fell timber. Raise walls and towers, recruit townsfolk, take on quests, and spend hard-won gold at the War Table.

🌙 Nightfall

Hold the wall

Ring the war bell and brace. Orks pour from every biome toward the keep — grunts, scouts, berserkers and warp-casting shamans. Survive until dawn.

A living warband sim

Not just a defense game — a whole island that works, fights and grows around you. Every shot below is captured in-engine, on Ultra.

⚔ Real-time combat

Blade, block & stamina

Soft-lock the nearest threat, then swing, crit and block on a stamina budget — or hold to charge a guaranteed-crit heavy smash. Four ork breeds, each with its own brain and bite.

  • Soft-lock targeting & combo chains
  • Charged heavy strikes & timed blocks
  • Grunts · scouts · berserkers · warp-shamans
The War Table upgrade tree — Prosperity, Bulwark, Champion and Armoury branches 02In-engine · Ultra
🌳 The War Table

Spend blood-won gold

A branching upgrade tree — blade, armor, abilities, walls and defenses. Climb the Prosperity, Bulwark, Champion and Armoury lines night after night, and carry every unlock down the bloodline.

  • Four branches, dozens of nodes
  • Walls, towers, ballistae & shrines
  • Upgrades persist across heirs
Villagers mining the desert crags and carting stone home at dusk 03In-engine · Ultra
🪓 A town that works

Villagers with real jobs

Woodcutters fell real trees; miners chip real boulders and cart the stone home. Lay out plots, raise houses and workshops, recruit and feed townsfolk — a town with its own food, repair and burn.

  • Woodcutters, miners & farmers at work
  • Build mode: houses, farms, walls, towers
  • Recruit, feed & muster a war party

🌙 Hold the night

Ring the bell, brace the wall

When the war bell tolls, grunts, scouts, berserkers and warp-casting shamans pour from every biome toward the keep. Man the towers, ballistae and shrines, repair the breaches, and survive until dawn.

  • Escalating nightly sieges
  • Archer towers, ballistae & healing shrines
  • Ring the bell to start the night on your terms
The knight breaks open a horde cage to free penned captives 05In-engine · Ultra
🔓 Free the caged

Break the pens open

The horde pens captives like cattle across the island. Clear the warband, smash the cage, and the freed take up arms at your side — every rescue another sword on the wall come nightfall.

  • Cages guarded across every biome
  • Rescues join your militia
  • More hands to build, mine and fight
The rival warlord's walled sandstone fort out in the cactus desert 06In-engine · Ultra
🏯 A rival in the sands

You're not the only lord

A Stronghold-Crusader-style human opponent holds a walled fort out in the desert — running its own tax economy, raising buildings and patrolling as it grows. Rush it early, or let it fester into a second front.

  • An AI keep with a live economy
  • Builds, taxes & patrols on its own
  • Raid it — or race it — for the island

— and there's more on the island —

🗺️

Five biomes & roads

Forest, snow, desert, rock and swamp on one island, laced with curving roads — each with its own camp, wildlife and weather.

💀

Gnashfang Hold

An ork fortress beyond the swamp feeds the waves — the Blight, patrols and towers that fire on sight. Breach it and end the Warlord to win.

🩸

Bloodline succession

When the hero falls, the next heir takes up the sword with every upgrade intact. Your townsfolk are your lives.

🧭

Guided by quests

A step-by-step quest chain eases you in — where to gather, when to build, how the trials work — so your first night doesn't blindside you.

🎒

Satchel & consumables

Loot chests, forage, and stock food and potions into quick-slots for the fight — eat to heal, quaff to buff.

First-person view

Tap V to drop into a first-person viewmodel — sword and shield in hand — and take the wall eye-to-eye with the horde.

The Bloodline

You are not one knight.
You are a line — and the blade does not fall when you do.

When the hero falls, the next heir takes up the sword with every upgrade intact. Your townsfolk are your lives. Lose the keep, or lose the last of the bloodline — only then is it over.
