Endless Mode

Introduced in the 1.5 update, Endless Mode provides a rigorous, infinitely scaling challenge that operates on entirely different progression vectors than the standard campaign.

How to Unlock Endless Mode​

You access Endless Mode via a broken portal in the Basecamp. You can unlock it in two ways:

  • Spend 120 Wrenches to repair the portal directly.
  • Complete a standard run on Guardian 1 difficulty or higher, which unlocks it for free.

Singularity and Glitch Mutators​

Endless Mode uses a dynamic difficulty scaling system based on mutators.

Upon completing each stage, the game automatically applies either a Singularity or a Glitch:

  • Singularity: A major, run-altering modifier that significantly buffs enemy lethality or changes fundamental rules.
  • Glitch: A minor modifier that introduces environmental hazards or smaller enemy buffs.

You must constantly adapt your playstyle to survive the compounding effects of these mutators.

Duo-Boss Encounters​

Every two to three levels, you are forced into a Duo-Boss encounter. You must face two campaign bosses simultaneously in highly confined arenas (for example, fighting Diggy Mole and IRIS concurrently).

Survival Strategy: This is a massive difficulty spike that invalidates standard boss strategies. You cannot rely on slow, methodical area-of-effect builds. You must hyper-optimize your early perk selections for single-target burst damage. Focus entirely on eliminating one threat as quickly as possible to reduce the incoming damage before turning your attention to the second boss.

Alternate Biomes​

Endless Mode features condensed, enemy-dense alternate versions of standard biomes. Expect to fight through challenging variants like the unique Corrupted Canyon, which forces tighter engagements and faster reaction times than the standard campaign levels.
