20XX 1.31.0 Test Notes - October 3, 2018

--TEST PATCH 1.31.0 --

Hello! Today's 20XX 1.31.0 test patch fixes some bugs, allows XInput control detection (finally!), makes a few Hawk changes (buffs), and allows Draco an alternate way to use his Dracocharges. It also enables stick-look on controllers!

Thanks for playing early!

REMINDER: to get into the test build, right click 20XX in your Library, click Properties, then the Betas tab, then pick "20xxtest" from the dropdown. You'll know it worked if the game name changes to "20XX [20xxtest]" in your Library list. This build is compatible with 1.30.4, so it still has daily/weekly challenges and online co-op enabled.

NOTE: The addition of a new keybind will reset your controls. (It should only happen the first time you load 1.31.0.)


  • Stick-look enabled on controllers that support it!
    • When playing, the right stick can now be used to pan the camera in any direction, up to a distance of about half a screen.
    • The camera will naturally gravitate back toward its normal resting point if you move away from your pan direction. (For example, if you pan to the right, the camera will re-center itself as you move left.)
    • Pressing in the right stick re-centers the camera.
    • This feature is disabled in enclosed spaces (shops, boss rooms/hallways) where it's not super useful anyway.
    • This functionality is not currently available on keyboards. If you'd like to see it, help suggest sensible defaults - we're not sure this feature makes sense without a controller, but we'd love to support keyboard use if possible.
    • The goal is to give players a little more control over what they see, especially when moving purely vertically, or very quickly horizontally - let us know how it feels!
  • Hawk changes! We'll revisit if we've gone overboard here.
    • Hawk now has four Power Slots.
    • Hawk's Siphon attacks that kill an enemy are now guaranteed to restore at least 1 NRG.
    • World Igniter NRG cost reduced by 20%.
    • Seeking Striker damage increased by 25%.
  • Added a new keybind! For Draco, this key is an alternate way to trigger Dracocharged attacks. For Hawk, this key is Power 4.
  • Added a "disable up-to-charge" option for Draco players who prefer to only use the new keybind.

  • Fixed an issue causing AL's cage to break early.
  • Fixed a rare issue causing the tutorial to affect the next run's Aug drops.

20XX 1.30.3 Patch Notes -- August 16, 2018

Edit, August 17, 2018 - we've just pushed 1.30.4, which fixes the multiplayer issue reported in the comments below, and fixes an additional input issue for players who bound BACK/its equivalent key to an action. (That button should work properly again.)



Hi, folks! Patch 1.30.3 is now live. It's mostly a bug fix patch - it fixes a handful of Draco-related issues, and resolves a crash that some players experienced in Endless play (or after particularly long play sessions).


  • Draco now has a Stats page.

  • Fixed a late-game crash that could occur when loading into a new level.
  • Force Resonator now properly works with Ace's melee attacks.
  • Draco's Supercharged Volt Edge now properly stuns enemies.
  • Fixed a few tile errors.
  • Deconstructor's Might no longer triggers retaliation attacks.
  • Fixed an issue causing some Blender settings to not be reset after game completion.
  • Kingseeker now prevents picking up HP items altogether, even if they were on the ground (or in an already-spawned Health Machine) when Kingseeker was picked up.
  • Fixed an issue allowing characters to pick up Weapons that don't belong to them.
  • Fixed an issue where games hosted by a Revenant would cause bad Weapon chest drops when the other player was not using a Revenant.
  • Fixed an issue where Draco could end up with Too Many Charges (toooo many chaaaarges).
  • Fixed an issue causing Volt Edge to destroy projectiles with Armatort's Core without charging it or having a Force Resonator.
  • Capped screen shake in certain outrageous cases to prevent game freakouts.
  • Crisis Lifebank now obeys the sacred laws of Save and Quit.
  • Fixed an issue causing Draco's power slot in the Pause menu to display the text of whatever was selected before if he doesn't have a Power yet.
  • Fixed Hawk and Draco's run completions not properly counting towards Contender.
  • Fixed a bug where Draco's Peacebringer wouldn't reset its combo state.
  • Fixed a bug causing the boss hallways to fail to draw while in Eternal Star or Death Lotus' boss rooms.


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.”
