20XX 1.11.1 Patch Notes - December 22, 2017

EDIT (Dec 24, 1:22PM EST): 1.11.1 is live once more. Tell us if anything awful happens!


Hello, and happy holidays! Today's 20XX mini-patch makes 20XX less greedy about your system & video card memory and fixes one bug.

Some players have been reporting black textures (and, in a few cases, even crashes!) since 1.11, so we're rolling this fix patch out to try and combat that problem. If you still see black textures or other weird visual artifacts in game, please tell us!


  • Reworked the way 20XX uses memory to make it more efficient over the course of a run.
  • Reworked the game handles Boss Drama pop-ups to be more memory efficient.

  • Fixed an issue that could cause Glory Zone completion to return the wrong set of Powers.

Thanks for reading!

20XX 1.11 Patch Notes - December 15, 2017

Hello! Today's 20XX Patch, Patch 1.11, is mostly a performance & bug fix patch. If you've experienced poor game performance or obnoxious bugs since 1.10, this'll get you running smoothly. Happy holidays!


  • Greatly improved text draw performance, room tile draw performance, and enemy/bullet draw performance. Most players should experience better framerates. Tell us!
    • The tile improvements might cause a few weird tile artifacts - please report any you see!
  • Fixed up cutscene performance.
  • 20XX now defaults to Borderless Window (instead of fullscreen vsync). V-sync will always introduce some amount of input latency.
  • Armatort's Dome (helm Core) now has a 50% chance to grant health when picking up an Armor capsule. (This is a buff.)
  • Permanent Skytemple Boltpairs are now a different color.
  • Upscaled a few visuals.

  • Fixed a million issues that we'd previously fixed, but 1.10 reintroduced.
  • Fixed a bug causing Re-Flapp to fail to damage Flat.
  • Fixed an issue with some spooky souls showing up before they're supposed to.
  • Fixed an issue causing the game to reset the Skull list when swapping languages. (Wow, this was a bad one!)
  • Fixed an issue causing Sharp's Mortar attack to fail with Furor active.
  • Fixed an issue causing Sharp's Splinterfrost splinters to move in the wrong direction.
  • Fixed a few issues with Kingseeker still leaving health sources in the game.
  • Cerby is now regular-sized again.

Thanks for reading!

“20XX perfectly recreates the feeling of Mega Man X, and generously adds all the procedural elements that players want out of an old-fashioned game these days.”

“It looks fantastic.”
