20XX 1.00.2 Patch Notes - August 18, 2017

Hello! Today's second post-1.0 mini-patch moves back an Aug (in the unlock order) that's likely to mess your business up if you take too many, slightly adjusts a few level pieces, adds a small QOL change for 4:3 resolution players, and fixes a bug that could cause co-op clients to fail to trigger game-complete achievements.


PS - if you look at our forums, you're aware that the current difficulty of Level 9 is a bit controversial. We're not in the kneejerk-reaction business, but we're keeping a close eye on it. If you want to give us some feedback in a super-easy to digest way, click here and tell us what you think!


  • Forcemetal Shell unlock cost increased to 16 Soul Chips. (Folks who've already unlocked it can ignore this.)
    • At its current position, new players that've unlocked up to Forcemetal Shell in its current spot are too likely to have runs spawning enough Shells to give players super negative speed. We're okay with veterans making that choice, but that feels pretty bad when you're just learning the game. At its new position, players will have either unlocked or be close to unlocking Contractor Plus, Hypersash, and Leafmetal - super negative speed will still be possible, but less likely.
  • Adjusted a few level segment configurations that were a little tougher than intended (and one that was very, very close to impossible under certain item conditions). For folks following the recent Level 9 discussions, one of the adjusted segments is a Level 9 piece.
  • Moved the camera boundaries in the final boss' room in 4:3 resolution so it's not cut off. 4:3 players - if you have other camera issues like this, tell me!

  • Fixed a bug that could cause co-op clients to fail to trigger game-completion achievements (like Survivor). We may have more work to do here, but this should get us most of the way there.

20XX 1.00.1 Patch Notes - August 17, 2017

Hello! Today's day-after-launch patch fixes up a few bugs players have found during 20XX's first day in 1.0, as well as a fix to make lower-end systems gracefully exit cutscenes they don't have the system resources to actually load instead of crashing. It also makes a certain helper less likely to be garbage.

(Note for folks still having trouble with the Soundtrack - get in touch! We're trying to get this fixed ASAP.)

Also: we've reset the all-time leaderboards. The game's "all time" score and time pages no longer make any sense and are full of impossible scores from old Early Access versions of the 20XX. Good luck!


  • Level 9/10's fast-moving droplet background is now disabled on Less High. We're hoping to add a better, more granular vfx control set before long, but if you're just dying to turn that moving background off, this'll do the trick for now! (If you play on Less High and really like this background, tell us! We're going to build a better VFX control layer, but if this change makes a bunch of people have less fun we'll fix it ASAP.)
  • Un-hid a few Achivements that were stubbornly staying hidden.
  • Online game clears now set the same Glory Zone unlock flags as non-online game clears.
  • Kur can no longer follow up a cube-wave with a dash if the wave's safe spot is the bottom of the room. (Cheapshot removal)
  • There's now a three second grace period at the start of a certain lategame sequence.
  • (Sort of a fix) AL is now much more eager to bust up things that might be in your way.

  • The Reveries achievement now triggers on lost runs.
  • Fixed the "Sorry to Jet" achievement.
  • Fixed a potential crash on super-low-end systems during cutscenes.
