Batterystaple Update - Mid-Sept 2017 Edition

Hey, folks! 20XX left Early Access 37 days ago. In the week or so after 1.0, I pushed a series of small hotfix patches to address a few issues that popped up, bringing us to (the current) 1.00.41 build of the game.

Things are going really well! Thanks for your support.

I'm in the market for a good way to keep you in the loop on what we're working on (now that we're not patching every two weeks), so I'm going to try a monthly update letter format. I'm not sure it'll always be around this time of the month, so at some point there'll be a little less or a little more than a month in between updates, at which point we'll stabilize. You might have noticed that holding ourselves to regular update schedules is a thing we like.

(I'm also after a better name than "Batterystaple Update" if we've got any bright ideas there!)


  • Launch went well!
  • We're going to update you once a month with what we're working on, now that we're no longer patching every two weeks
  • Polish patch (not content!) 1.01 is coming soon(tm) - probably in the next week, mainly QOL fixes (double-tap dash, looking at you) and a bunch of bug fixes
  • We're full-steam-ahead on porting 20XX to consoles - more details about our platform targets and when they'll hit as we get them
  • We're working on 20XX's post-release content plan in light of launch, our sales, and player base, and will share details once we're ready to promise them

Next up for 20XX: Patch 1.01

1.01 is a polish patch. I'm chewing through the bugtracker in mantis as quickly as I can (bonus: I've also fixed its spam problems!), and am seeing which fan-favorite updates from the community I can get into the game in a pretty reasonable time frame. 1.01 is not a content patch, but it will likely change the way Seed Racer behaves to bring it more in line with challenges (so a seed racer seed is a seed is a seed). There's a messaging issue with how we report the seed in normal/defiant play (since a player without everything unlocked will see something different if they load that seed later) - we're ironing out as we speak.

In a separate branch from the live build, we're spending a ton of time working on porting 20XX to consoles. We're not ready to dig into exactly when and which consoles we're hitting yet, but that work's going to yield some technical benefits for the Steam version of the game. We're getting the chance to revisit some old technical implementations (read: we have to, because some of my choices are incompatible with what consoles require), which should result in a smoother gameplay experience. (It'll also fix any remaining text display bugs.) Of course, whenever that merge first shows up in the live build, we'll be on hand to quickly fix any mistakes we've made just as quickly as we did in Early Access. Further netplay improvements will come down the line as part of those porting changes, as well.


Talk to us about more content!

We're working on that! Critically, we're figuring out what our future in the games industry looks like in the coming weeks, and the direction we take is going to inform what we do with 20XX going forward. As soon as we've got concrete plans here, we'll share them with you. Feel free to ask specific questions if you have them (on here/on twitter/via email, depending on how publicly you want to ask) and I'll do my best to answer what I can.

Thanks for reading and for playing 20XX! The only reason we get to deal with the "what do we do next?" problem at all is because you bought our game and said nice things about it.

20XX 1.00.4 Patch Notes - August 23rd, 2017

Hello! Today's 20XX patch improves netplay performance, adds ultrawide support, and fixes the Fox Only achievement.

Note: I'm going to be out of town from Friday, Aug 25 through Saturday, Sept 9th on a PAX-plus trip. I'll have limited access to internet for support, but it's not super likely that 20XX gets patched over that period, other than showstopper bugs I'm able to fix on the road.


  • Netplay performance improvements! We've tightened up how 20XX's netcode handles certain kinds of data - the result should be fewer drops of data you care about, and better overall performance (especially on lower end machines).
  • Ultrawide support! We compromised on this. Ultrawide should now work properly up to 21:9, but will be black-barred to 16:9 in Challenges. (Your UI'll still be drawn outside the game view.)

  • Fixed a bug that'd prevent the Fox Only achivement from triggering.
  • (edit, Aug 24) Fixed a very specific case where a certain sequence could cause framerate drops in online co-op with one player dead.

  • 20XX's online multiplayer doesn't play super well with alt-tabbing from fullscreen. We'll address this in a future patch, but the testing burden involved is a little too heavy for the time I have in the next few weeks.
