How it plays

01

Choose your faction

Humans, Undead, Demonics, or Greenskins. Each has 6 unique unit types with different costs, movements, and special abilities.

02

Draft your warband

Spend 75 XP to build your team. Must include a King and at least one Pawn. Every point is a tactical commitment — no two warbands are alike.

03

Deploy and battle

Place your units in your spawn zone, then take turns moving one piece. Capture enemies by moving onto their square. Terrain matters — water blocks, gaps divide, corridors create chokepoints.

04

Capture the King

The game ends the moment a King is captured. Protect yours, hunt theirs. Check forces a response — but there's no stalemate here.

THE FACTIONS

Four factions. Zero symmetry

Each faction brings unique units with different costs, movements, and special abilities. No two warbands play the same.

⚔
Humans
Balanced generalists. Archers attack across gaps, the Wizard splits movement and attack, and the Princess slides like a bishop.
💀
Undead
Movement trickery. Wraiths phase through gaps, the Vampire reverses move/attack axes, and the Warlock attacks diagonally at range.
🔥
Demonics
Devastating firepower. Kobolds and Iron Golems use cannon attacks — sliding through a screen piece to strike at range. The Red Dragon attacks as a knight.
👺
Greenskins
Brute force. Goblins and Ogres bring cannon attacks like Demonics, while the Shaman commands full queen movement. The Warlord strikes as a knight.

MOD HOOKS

Fork the dungeon. Rewrite the rules

Every game constant lives in plain JS objects you can fork and edit.

◈
data.js → UNITS
24 unit definitions with type, faction, XP cost, and cannon behaviour. Add new units, rebalance costs, or create a fifth faction.
◈
data.js → MAPS
Board layouts as grid arrays — walls, water, gaps, and spawn zones. Add new maps or reshape existing dungeons.
◈
data.js → SP_INFO
Faction metadata — names, accent colours, descriptions. Rename factions, change themes, or add asymmetric flavour text.
◈
state.js → XP budget
Draft budget and AI draft logic. Change the 75 XP cap, adjust AI weighting, or add draft constraints per faction.
