All updates

Choose your next front. Find a reason for the next run.

Spire 1–20 adds a challenge ladder after your first victory. Optional Mutators change the rules, and new front choices after Waves 10 and 20 let you weigh a different kind of pressure against its reward.

Game Update #10

Victory opens Spire 1

  • Win the base 30-wave run to unlock Spire 1. Each eligible victory opens the next step, up to Spire 20, and lower unlocked levels remain replayable.
  • Each level adds one authored rule, with earlier rules staying active. Changes include ammunition, support reach, escorts, charges, splitting, summons, boss patterns and repeated spending.
  • This is not a blanket health-and-damage multiplier. The selected level is fixed for the run and recorded with the result; progress is saved locally.
  • These difficulty levels are separate from the Foundation, Fortified and Ascendant chassis silhouettes shown on the home page. A bigger-looking machine is not an extra Spire level.

Combine up to three optional Mutators

  • After your first victory, Run Setup lets you choose up to three Mutators alongside an unlocked Spire level, or roll a seeded random selection.
  • Narrow Market removes one regular Market slot in exchange for cheaper paid rerolls. Blitz Assault makes ordinary enemies faster and increases their Scrap rewards, with exceptions for bosses and other special units.
  • Siege substitutes additional ranged pressure into normal waves. Resonance Fever adds bounded build-link opportunities after your first Tier III mutation.
  • Mutator runs keep their victories and machine records, but they do not unlock the next Spire level. Mutators change a run's rules; weapon mutations change weapon behavior.

Choose the next front after a boss

  • After Waves 10 and 20, choose between Swarm and Siege pressure for the next four waves: Waves 11–14 or 21–24.
  • The choice presents the pressure and its Scrap or Hull-repair reward. Clear the four consecutive waves to earn the reward; choosing a front does not grant it immediately.
  • The decision pauses both the world and Market time and preserves the existing Artifact-choice order. The selected front appears in forecasts, the guide and the run recap.
  • These are two encounter decisions inside the existing three-chapter run, not extra worlds, a map-navigation system or the separate optional Siege Mutator.

Your build still has to survive the choice

  • Independent weapons, Tier III mutations, Artifacts and Resonance remain the tools for shaping a machine. A front choice changes what that machine will face rather than handing it a finished build.
  • Front rewards, Mutator combinations and the cumulative Spire rules are provisional. More options do not prove that every combination is equally viable.
  • Weekly ranked challenges remain a separate development preview. Public ranking and player run submissions remain disabled.
