Co-op

Built for one to four.

Solo is a puzzle. A party is a pact.

  • Your board, your call.

    Every player owns one grid and fights the boss in parallel. Nobody can touch your build.

  • Draft the boss together.

    One shared row of encounters. Everyone claims a different one, then fights it alone.

  • Win or lose as a party.

    The run is scored on ten shared nemesis fights. Six wins and the whole party takes it.

The Rescue

Nobody stays down.

A teammate's board falls. The server hands you their fight.

Last one standing? You take every fallen teammate's fight in turn, until one beats you.

The Forge

Runes don't attach. They project.

The track on the right projects across two rows. The track below projects down two columns. Park a unit in the crossfire and it catches both.

Drag a rune onto the track on the right (rows) or the track below (columns). Drag a unit anywhere on the grid, or drag a rune off the board to remove it. Hover or tap a placed rune to see its lanes. On normal 2×2+ units, 0.5× means one lane intersects and means both do. Runic and size-1 units stay at full effect.

  • Forge by matching

    Two of the same rune on one track forge into the next tier. T1 → T4.

  • Tribe-gated

    Some families only fire for one tribe. Bastion shields Sentinels and nobody else.

  • Keyword carriers

    Inferno carries Burn, Toxicity carries Venom. Stack the family, scale the tick.
