What the developers have to say:

Why Early Access?

“Because it's a ton of fun and our fans asked for it! Our players have had a blast playing 20XX as it develops and helping mold future builds of the game with their feedback.”

Approximately how long will this game be in Early Access?

“The game's already great, but it'll be done when it's done! We update the game every two weeks like clockwork, and will keep doing so until our full release.”

How is the full version planned to differ from the Early Access version?

“The game's final challenge levels are not currently in the game, and will be released as we reach 1.0 and leave Early Access.

Other than that, most of 20XX's features are in their release state at this point.”

What is the current state of the Early Access version?

“It's nearly feature complete, and the game contains no major/crash bugs. Don't take our word for it, though! Read the reviews.”

Will the game be priced differently during and after Early Access?

“20XX's price rose steadily over the course of Early Access, but has reached its final price of $14.99. We have no plans to change the price further at this time.”

How are you planning on involving the Community in your development process?

“We love feedback. Amazing fans give amazing feedback, and we want as many of those fans as possible to experience 20XX before we declare the game finished.”

20XX 0.981b Update - June 23, 2017

Hello, friends!

This is an update to Wednesday's 0.981b release, adding support for Spanish, Portuguese (Brazilian), French, German, Russian, Chinese (simplified), Japanese, and Korean to 20XX.

If you don't have an existing .opt file, 20XX will try to detect the right language based on your Steam Client, the Language you set for 20XX, and your operating system. Else, you'll have to change it manually!

Thanks, and enjoy! Let us know if anything seems off with the translations (ideally in the form of a mantis bug post.

20XX 0.981b Patch Notes - June 21, 2017

Hello! Today's 20XX patch overhauls Casual into Reverent, comes very close to adding several new languages to 20XX (see below if you want to help us out!), and more!

This patch comes very close to adding support for several new languages to 20XX - in preparation for the new Language option to the Settings menu, we've reset your options file. Your keybinds should be fine, but player-specific control options (quick drop, etc) are reset.

NB: This patch is hitting a little early because I'm out of town, and won't have access to a computer at the normal update time. I'll be around to engage with folks later tonight/hotfix as needed.

Disclaimer: 20XX is in beta. As we develop the game, we may make changes that require us to invalidate or wipe your 20XX save files, Steam Leaderboard info/achievements, and other save-y stuff like that. Be aware!

TL;DR for today's patch: Reverent mode! Almost languages! Save nuke option!

For pretty much every patch from here on out: Polish forever! Forever. (More netplay.)

As always, let us know if anything's busted or if we missed a change.



  • Very shortly - hopefully as a hotfix to this patch - 20XX will be introducing support for new languages. We've been working really hard on it, but need a little help testing the languages for folks whose primary language (and ideally operating system/keyboard layout) is Spanish (Latin American), Portuguese (Brazilian), French, German, Russian, Japanese, Korean, or Chinese (Simplified). If this is you and you want to lend us a hand, click here and get into the language beta!
  • Casual Mode's being replaced with a different "lighter" mode: Introducing Reverent Mode!
    • Before we get into the details, let's talk about our rationale a bit.
      • When we first implemented Casual, our goal was to provide an easier way to get into 20XX so that newer players could find their footing if Normal wasn't their thing.
      • Casual did kind of a bad job of this. Casual isn't that much easier than Normal at first (since a new player's limited unlocks don't let them start with very much), and starting on Casual also forces new players to make a choice about something they know very little about (choose 3??). The name "Casual" is also a little rude to some players - we can do better.
      • We understand there's a market for the current Casual Mode - some folks like the scaling that comes along with being able to choose your powerful new unlocks, and some folks just like being able to experiment. Our goal is for the Power Progression update (which we're still working on - see the big FEEDBACK PLS thread from previous patch notes) to scratch this itch.
      • With Reverent, we're adding a mode that better serves the goal Casual was meant to fulfill - a lighter, more accessible 20XX mode that new players can jump into to learn the game. (Or play indefinitely. You do you.)
    • Reverent pays homage to 20XX's ancestors, granting players three lives to complete their quest (instead of choosing 3 Augs to start with).
    • A life is consumed any time you'd've otherwise gotten a Game Over (so in co-op, a "life" is only gobbled up when you both die).
    • If you die before the boss hallway, you'll respawn at level start.
    • If you die after the boss hallway, you'll respawn in the boss hallway, right before the boss.
    • When you die, shop items and chests don't reset. All items collected are still collected, and all nuts spent are still spent.
    • All enemies and machines respawn.
    • Glory Zones stay locked if you succeeded at them before dying, but will give the player another shot if they fail, then die.
    • Respawns spawn all players at full Health and Energy.
    • No achievements can be unlocked on Reverent (once they're available in the live build).
    • Other forms of progression (Soul unlocks, to-be-implemented power progression, one-run Augs, Undeveloper) all function normally on Reverent.
    • We totally understand that this might be super controversial - we're keeping a close eye on it. Reverent's definitely easier than the previous Casual!

  • There's now a "delete save data" option from the Main Menu. It won't show up while in the lobby/in a game. It'll reset the game as though you'd just installed it, but it won't reset your controls.
  • Modified player speed scaling slightly. This change does nothing at all before +9 speed - all speeds after +8 are now slightly faster.
  • Jump now scales the same way. Jump will be slightly less effective past +8, and much less effective past +16.
  • When equipped with the full Dracopent set, charge particles now skip the first color (to reflect the fact that all attacks are at least normally charged).

  • Fixed a bug causing Lotuses to rotate far faster than intended.
  • Fixed a bad Frostor icicle thrower.
  • Fixed an Agnisort bug causing the game to sometimes count platforms with blue flames as "safe" after falling in lava.

  • The Reverent lives counter still displays when navigating menus after a Reverent run. It'll likely be hotfixed tonight or tomorrow morning.
Thanks for reading!
