Batterystaple Update - November 2017 Edition

Hey, folks! It's just about December, so it's time to talk about what we've been up to.

Three things are on our mind.


Patch 1.11

We changed a *lot* about the game's internals in Patch 1.10, and it's come to our attention that a few things aren't perfect - cutscene performance has taken a hit, and some players are reporting worse performance overall. We've also caught a few obnoxious bugs that've worked their way back into 20XX that ought to be gone, so we're spending a lot of time eliminating those and working on the optimization to end all optimizations, which we're hoping will put performance issues to bed for folks on older machines.

Patch 1.11 will address these issues, and come in the next few weeks. I'd love to be able to say for sure it'll come next week, but it's competing for time with our next focus - we're getting ready to take the game to Playstation Experience next weekend (Dec 9-10)!

Our internal goal is to get Patch 1.11 out absolutely no later than Friday, December 15th. It may be out earlier if we can get it all tested in time - we'll do our best.


Playstation Experience - Dec 9-10!

Since you're reading this on Steam, this might not concern you too much, but it definitely concerns us! We're hard at work on bringing 20XX to consoles, and we're happy to share that we'll be showing off 20XX at Playstation Experience in Anaheim next week. If you're going, come say hi!


Patch 1.20

We're going to talk a lot more about this next month, but we've begun laying the groundwork for 20XX's second post-release content patch, Patch 1.20. It's got a bunch more content that we'll talk more about in next month's update, and we're targeting some time in January for it (much in the same way that we targeted "some time in November" for patch 1.10). Stay tuned!


Thanks for reading!

20XX 1.10 Patch Notes - November 24, 2017

Hello! Today's 20XX patch -- Patch 1.10 -- is a content patch. It adds several new Augs, lots of new level pieces, some new visual effects, and overhauls a good chunk of the 20XX engine. It also contains a ton of tweaks, fixes, and QOL changes!

That's all! It doesn't contain anything else. Nope.

NB: We've changed a few animations for Ace and Nina, and their texture sheets have changed a bit. If you're using graphical mods for these characters, this patch likely breaks them until they're updated by their creators. Sorry for the hassle!

Also NB: 20XX's online co-op has a reconnect feature! If you crash or otherwise disconnect, the other player can stay in the game while you reboot 20XX, enter HQ (the Hub), right click your friend in the Steam Overlay, and click Join Game. This isn't new, but we've been pretty bad at messaging it.

Triple NB: Today's patch reworks 20XX's font system. As a result, the first time you run the game or change to a specific resolution for a given language, the game will take a few seconds to generate the font files it'll need. If you notice short delay when changing to a given resolution or language for the first time, don't panic!


  • Added 10 new Augs, including three Prototypes, three Once-per-Run Augs, and four stackables.
  • New level pieces! Multiple themes (especially Level 9) now have additional level variations.
  • Text drawing improved! (It should now be much more readable, too.)
  • In preparation for some future technical work on 20XX, we've rewritten some major pieces of the game's engine. In general, we expect that most players should see better load times and faster performance, but we'll be vigilant about any issues this may cause for some players. If you consistently feel like your performance has gotten worse (with the same resolution/gfx quality), please tell us!
  • Regenerative Plating now restores 2 HP on pickup, in addition to its other effects.
  • Reworked Primary Weapon Chest drops. They now *do* take previous Primary Chests into account, but *don't* take your current weapon into account (so it's possible to find the weapon you're using, but shouldn't happen without the other weapons being rolled first).
  • Armatort's Dome (Head Core) now has a 50% chance to restore 1 Health when picking up Armor. (This only applies to the +2 Armor Capsules, and not to anything else that grants Armor.)
  • In response to a lot of player feedback from our achievement hunters, we've scaled back the Endless achievement requirements (Extended, Everlasting, Eternal). 20XX's harder achievements are challenge-based, not grind-based, and these achievements left completionist players feeling worn out by the grind.
    • Extended now requires clearing Endless level 16 (down from 25).
    • Everlasting now requires clearing Endless level 25 (down from 50).
    • Eternal now requires clearing Endless level 40 (down from 100).
    • We understand that if you've previously played a ton of Endless and cleared level 100, this might feel cheap, and if you've ground up to 40+ and stopped, it feels bad that you don't already have Eternal. If you're really bothered by this, drop me a line and we'll set things straight.
  • Lightning removed from the Bold, Probably Cheating, and Fervor achievements.
    • Lightning mucks with the game's mechanics in a way that no other Skull does, and it feels pretty bad having it tied to any Achievements.
  • Removed some obnoxious Rollster spawns from Level 9.
  • Glory Zones will spawn past Level 8 in Endless again.
  • Seed Racer now properly behaves/displays score like a Challenge.
  • Improved Boomerang Blade diagonal throw detection for controller sticks.
  • Plasma Blender nerfed slightly. As Ace builds the rapier's size and damage by attacking foes, the damage will now ramp up 25% slower than before. It'll deal 12.5% less damage at maximum size without Dracopent's Claw, and 16.7% less damage with Dracopent's Claw. The initial hits from the Blender (at minimum size) are unaffected.
    • The Blender is still very, very powerful, and we may need to go a bit further.
  • Added a handful of spicier visuals!
  • 20XX now immediately loads into a screen-sized loading screen (instead of a tiny window in non-fullscreen, or an empty black screen in fullscreen).

  • Fixed an issue causing Glory Zone BLP to fail sometimes. (This means we're back to "maybe we overdid it!" status, so let us know if you think you're seeing too many Glory Zones.)
  • Fixed a runaway Armor display issue.
  • Fixed a bad Pause Screen display in local co-op causing both players' Health/NRG numbers to draw in the status section.

  • Some players may experience cutscene slowdowns. Tell us if this is you!

  • Anomaly Report AR-903 indicates [REDACTED] models of [REDACTED] and [REDACTED] may persist in the Network.
  • Gaze up, and try to remember them.

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.”
