How the game changes

  • Weapons and arms are shuffled, with optional movement, alternate-fire and skull unlock items.
  • Secrets provide checks; optional challenges, Perfect Ranks and other objectives expand the pool.
  • Unlock individual levels or whole layers, then clear enough stages to access your chosen goal level.
  • Filler rewards provide currency or temporary bonuses, while configurable traps interfere with movement, equipment or enemies.

Before you start

  • Use r2modman or Gale, or install manually with PluginConfigurator and the required mod loader. Install the matching ultrakill.apworld for generation.
  • Start on a fresh save slot and do not complete the tutorial first: its flags can prevent connecting. The NoTutorial companion mod is optional.
  • Logic assumes intentional damage is acceptable. Choose exclusions and check types to match your skill; game difficulty can be changed between attempts.
  • This entry confirms the documented Windows route, not independently tested Proton support or compatibility with multiplayer mods.
  • Use 3.5.6 for its slide and Gutterman shield logic corrections, skull-spawn fix and revised Idol requirements.
