Patch 17d Changelog

ULTRAKILL · published 15 Apr 2026, 17:17 UTC

All newsPlayers around this dateRead on Steam
  • Improved optimization on non-portal levels and the Cyber Grind
  • Made the Friends leaderboard at the end of a Cyber Grind run scrollable
  • The 75% wave completion requirement for opening Deathcatcher cages now excludes the Deathcatchers themselves, reducing the amount of other enemies the player has to hunt down to open them
  • If a Deathcatcher cage spawns on top of the player in the Cyber Grind, the player will now be teleported above it instead of getting stuck inside
  • Fixed enemies sometimes not dying when falling from a fatal height
  • Fixed a broken navmesh in 2-2's first area causing a group of Soldiers to spawn in the wrong location
  • Fixed a bug that caused the Sawed-On Shotgun's chainsaw to still appear broken after respawning if it was broken before being launched
  • Fixed a bug that caused the Sawed-On Shotgun to no longer be able to use the primary fire while chainsaw meleeing
  • Fixed the Earthmover boss health bar replaying its intro fill animation when the player grabs a checkpoint

  • Made Wind state breaking breakables and glass more consistent
  • Fixed a mysterious black blob sometimes appearing on the portal leading from 8-3 Split Color Door to Night Street
  • Ejected cores are no longer launched by non-Knuckleblaster explosions
  • Fixed Malicious Face beams not causing core ejects to nuke
  • Added a buffer safety system to the alt fires of the Core Eject Shotgun and SRS Cannon Rocket Launcher to avoid the player accidentally firing a 0 force projectile when switching to the weapon
  • Fixed a bug that caused Mannequins to inherit a broken version of the Husk chest explosion mechanic
  • Fixed the electricity particles of the Electric Railcannon and Malicious Railcannon not displaying correctly
  • Fixed the Railcannon pips not working correctly sometimes when using a Dual Wield powerup
  • Fixed a bug that caused a Power's health bar to appear for a single frame at the beginning of his spawn animation in 8-3
