Hello! Today's 20XX 1.42.0 patch fixes an ancient invisible enemy bug, adds Russian Datalore, and sets up crossplay with Epic build of the game! It also adds a new matchmaking feature aimed at public users on different platforms. At this time, 20XX supports crossplay only between Steam and Epic, via the reworked public matchmaking system. I know we've got some players concerned about the changes, so I thought I'd take a little time to explain what's changed, and why we did it.

20XX's friends-matchmaking is totally unaffected by these changes. (If you have a friend you primarily play with on Steam, this shouldn't affect you at all.)
20XX public matchmaking now uses Epic's backend services (instead of Steam's). For most players, this should result in no difference in matchmaking quality.
We chose to do this because our data tells us that 20XX's public matchmaking on Steam is largely not used by players - most players play with their friends or find friends via Discord. Most reports we've gotten about the 20XX public matchmaking experience are "I hosted a game for awhile and no one joined, so I stopped."
The best way for us to help fix that is by giving Steam players a bigger pool of public partners to play with! (If the issue really needs "fixing", anyway - after all, 20XX has been out of Early Access on Steam for almost three years.)
We made a few changes to public matchmaking's featureset to accommodate crossplay. Again, to be super clear, none of these changes affect friends-co-op.

Challenges (Daily/Weekly/Hardcore etc) are no longer playable in public co-op matchmaking. Everything else should work fine! This feature (in public co-op) has gone almost entirely unused since we added it, but we'll keep a close eye out for folks affected by this change.
Public matching now uses a "passphrase" system to filter the lobbies available when you search. (See below for details.)
Reconnect relies on Steam's lobby implementation, so that won't work in public online play anymore. (It didn't really work unless you were playing public with a Steam friend of yours, though, anyway, since you have to rejoin via the Steam Overlay.)

We'll keep a close eye on player feedback here - we feel we've overhauled a feature that players aren't using, but as always, we're looking out for your thoughts on the changes.
Thanks for playing! CHANGES:

Public play now uses a "passphrase" system to find lobbies. When searching for a game, you'll only return games that match the passphrase you set before hitting "join" - when you host with a passphrase, players will only see your game if they type it in exactly. This lets players coordinate across platforms where we don't have traditional support for friends/invite systems.
Leave the passphrase blank if you're looking to find a random partner!
This new public matching system applies to all players on either Epic or Steam - the passphrase system applies on both platforms, whether a passphrase is used or left blank.
Improved Seed Racer entry UX (it uses the same logic as the new Passphrase system) - controllers can now enter/exit the field entry instead of it feeling like the game's softlocked (because it previously ignored controller input), and the text field's highlighted while active.
The other changes from 1.41's last test push, which never made it live! The notable one here's an ancient invisible enemy error.
Added a Russian translation of the game's long-form Datalore for Augs, Enemies, and Bosses, courtesy of Canary, a member of 20XX's community. Thanks!

Hello! Today's 20XX 1.42.0 test patch paves the way for crossplay with the upcoming Epic build of the game. It's not super exciting - the exciting part is all the new players coming next week, but we thought we'd get this out a week in advance and see if there are any ancient bugs we ought to squash. It's live on the test branch now (public branch "20xxtest"). Thanks for playing! CHANGES:

30XX in the Steam Summer Festival! & May Town Hall Info
Hey, folks! This post also appears in the 30XX feed. If you've seen it there, disregard! We're happy to get to announce that 30XX will have a playable demo during this year's Steam Summer Festival! You'll be able to get a taste of where the game's headed well before we get there.
13 Feb 2020Developer post
The year is... 30XX!
Hello! Today's 20XX patch... wait! No! Not that. Not today. Old habits die hard. Today, we're excited to reveal what the team at Batterystaple has been working hard on since we finished our full-time work on 20XX. A thousand years go by in an instant, and here we are: the year 30
Hello! Today's 20XX patch... wait! No! Not that. Not today. Old habits die hard. Today, we're excited to reveal what the team at Batterystaple has been working hard on since we finished our full-time work on 20XX. A thousand years go by in an instant, and here we are: the year 30XX. 30XX is a full-fledged sequel to 20XX in with a brand new art style, courtesy of the masterful Glauber Kotaki (animator of Rogue Legacy, Duelyst, Chasm, and more). Some big highlights along with the visual overhaul:

8 brand new level themes (no more sharing between bosses!), each with their own visual aesthetic, radical tunes, and fearsome Guardian to be overcome.. if you can!
Distinct movesets for our heroes - Ace has had hundreds of years to study techniques beyond his comprehension in 20XX, and is ready to adapt to anything!
Radical new metagame progression that puts the game's challenges squarely in your hands, however you see fit!
So, so much more that we're excited to share in the coming weeks and months!
We won't be spamming 20XX's announcements too regularly, so here are a few great ways to keep tabs on the game while we're making it:

Sign up for our mailing list! You'll get the latest news on development in a casual, "hey bud here's what I'm working on!" kind of style.
Join the Discord server!
Follow the team on Twitter!
Of course, wishlist 30XX! With every wishlist, we grow stronger. It really helps!
Keep being amazing and tell your friends - we're seeing a fantastic reaction to the game already!
If you bought 20XX yesterday or if you've been here since 2014, thank you so, so much for the support - it's insane to us that we get to even consider making another game, and the fact that we've assembled the amazing team we've got for 30XX still has me in disbelief. Cheers CK

Hello! Today's 1.41.0 patch fixes a few small things. Nothing much to see here! (Unless you're unhappy with our recent Plasma Blender change, in which case you're about to be happier or even less happy.) Thanks for playing! -- CHANGES:

Plasma Blender size-gain-on-combo restored to pre-1.40 levels. Plasma Blender combo damage scaling reduced by 50%. (Previous base damage was 10-17.5 at max size - new damage is 10-13.75.) Overall, this is about a 20% maximum damage nerf without Dracopent's Claw, and a 30% damage nerf with Dracopent's Claw.
Draco now charges Quint Laser in 1 second per stage. (Down from 2)
FIXES:

Fixed noise clutter when charging Quint Laser with Autocharge on.

Hello! Today's 1.40 patch introduces a few much-requested features, fixes a handful of bugs, and introduces Revenant versions of Hawk and Draco. It also adds fully translated Datalore for German! It also introduces some test metric collection that we'll improve over time - 20XX will now collect a small amount of usage data (completely anonymized, not tie-able to a given player or their Steam ID whatsoever) that'll help us balance the game going forward. An opt-out toggle is in Advanced Options if desired. Thanks for playing! -- CHANGES:

Hawk and Draco now have Revenant models of their characters.
When Nina hits a Boss with 2-3 shots in a row, the attacks after the first now do more damage (1.0x/0.8x/0.8x, up from 1.0x/0.5x/0.5x). This means that a base 3-hit combo from Nina now deals 10+8+8 = 26, up from 10+5+5 = 20. (This may be 0.1x too far. We'll see!) This change also applies to Draco's projectile combos.
Nina's (and Draco's projectile) shot-refresh timer (the time after which a shot no longer counts as "on screen" for "can I shoot again?" checks upped to 0.75s (from 0.5s).
World Slug removed. The world now moves at an appropriate pace.
Added Auto-charge in Advanced Options. We know this one's contentious, but we've (finally) decided to add it - folks who play the game a lot report hand pain as a limiting factor in their time spent playing 20XX - and we're trying it out.
Death Lotus will now ping his next emerge location a bit in advance.
Steam users J.Clockson_YT and xankrieger have translated the game's detailed enemy & item Datalore into German! (So it's now available in German.) Some of the descriptions run over the text box size. Turns out German uses a lot of characters.
In Endless play, 20XX will now forget what items it's generated every ten levels as long as the endgame gauntlet hasn't begun. This means Once Per Run items will spawn again - repeated pickups won't do anything.
Rebeginners past the third available unit will no longer display or factor into the Repro chain.
Plasma Blender's combo-size-growth rate reduced by 33%. (It's now smaller when combo-charged.)
Increased charged Rapture's speed by 50%. It also now counts as a wall for enemy projectile purposes - it'll block any shots a wall would normally stop.
Scatterblast now fires 2 additional projectiles when charged.
Courtesy of player Cwolfcommander, we've got some better-fitting Autumn and Dvorac character models!
As a pilot program, the test client now defaults to reporting a small amount of player usage data. The data is anonymized, and contains no personally identifying data whatsoever.

The game currently collects info on how often the eight basic Powers are chosen relative to how often the player has the opportunity to acquire them. It also collects level start/end data, indicating what level (number and theme) players are dying in most often.
You can opt out of metrics generation in Advanced Options.

FIXES:

Fixed what I'm hoping is the primary cause of co-op play Endless run crashes.
Implemented a potential fix for the "vaulting" issue some players have noticed.
Fixed an issue that could cause enemies to rarely appear out of nowhere (they were being reset to their spawn points at really inopportune times). This usually happened with Agnisort Bzzombs (bees), but was possible elsewhere. This may also take out the rare "invisible enemy" bug where you collide with an enemy hitbox that you can't see or shoot.
Fixed an issue where black-square Prototypes could appear late in Endless runs.
Fixed an issue where Save & Quit resulted in catastrophic Nut Loss.
Fixed an issue where Intensifier wasn't boosting Vika's charged shot.
Fixed Murderdrone doing 8 damage (should be 10) - did I change this on purpose?
Entropy Lock no longer shows up in Boss Rush.
Fixed an issue where the Get Equipped & Provoke achievements would fail to trigger for the client in online co-op.
Fixed an issue where Meganut could be taken into Challenges (if it spawned in HQ as a next-run item).
If the game window loses focus while it's unable to pause (say, because you're looking at a boss intro), it'll pause as soon as it can (instead of not pausing).
Fixed Draco's Rapture & Gemini weapons (bubble, bow) not respecting shot limits.

As a first test, the game currently collect info on how often the eight basic Powers are chosen relative to how often the player has the opportunity to acquire them. It also collects level start/end data, indicating what level (number and theme) players are dying in most often.
This is a test of the system - we'll collect more meaningful data as we develop this test branch before it goes live.
You can opt out of metrics generation in Advanced Options.

FIXES:

Fixed an issue preventing Dvorac from picking up Draco's Primaries.
Fixed an issue causing the second player in a game involving Autumn/Draco/Dvorac to get the wrong item after a boss.

Leaderboards should now show Dvorac/Autumn's names properly. (This should work retroactively, too.)
Fixed Draco's Rapture & Gemini weapons (bubble, bow) not respecting shot limits.
Fixed a bug allowing Dvorac to pick up Core Augs. (They'd still only drop in Challenges if he was alone, as intended.)

Hello! Today's 1.40.0 Test patch introduces a few much-requested features, fixes a handful of bugs, and introduces Revenant versions of Hawk and Draco. It also adds fully translated Datalore for German! We've got more to do, but that's all we've got time for this week. ICYMI, we're still collecting feature requests as we prepare to move full-time to other projects here. We've also seen some discussion lately about character balance, so I've opened up a thread to chat about that, too - hop in. This test patch will likely be updated a few times with additional work before it goes live. Thanks for playing! -- CHANGES:

Hawk and Draco now have Revenant models of their characters. The art for these may or may not be final - at present, they're recolors.
When Nina hits a Boss with 2-3 shots in a row, the attacks after the first now do more damage (1.0x/0.8x/0.8x, up from 1.0x/0.5x/0.5x). This means that a base 3-hit combo from Nina now deals 10+8+8 = 26, up from 10+5+5 = 20. (This may be 0.1x too far. We'll see!) This change also applies to Draco's projectile combos.
Nina's (and Draco's projectile) shot-refresh timer (the time after which a shot no longer counts as "on screen" for "can I shoot again?" checks upped to 0.75s (from 0.5s).
World Slug removed. The world now moves at an appropriate pace.

Hello! Today's 20XX 1.31.3 patch fixes a few more bugs and lets Nina's primary weapons fire a bit more often. This patch will be followed up by another much quicker test/live push changing Nina's "inactive" shot timer to 0.75s (from 0.5s), but I'd like to give that patch a few days to breathe on test before pushing it live. Additionally - we're currently looking for a bit of feedback on the game's future going forward as Batterystaple focuses on new projects full-time - please see that thread here. Thanks for reading! -- CHANGES:

Zookeeper's Burden no longer grants a Skittery Smuggler in Challenge runs, or when the Bankrupt Skull is active (since it'll have nothing to eat).
Nina's shots now count as "inactive" for purposes of her shot limit shortly after they spawn, instead of once they disappear. (This helps prevent the feeling that she's shot-locked without altering the the attack's speed or lifetime.)
FIXES:

Fixed an online multiplayer issue causing weapon/power pickups to behave strangely in some setups.
Fixed an issue causing Force Resonator, Armatort's Pound (Arm Core), and Scatterbeam to fail to work together properly.
Fixed an issue causing The Volunteer to fail to convert Shops into Very Safe Labs.

Hello! Today's 20XX 1.31.1 patch adds auto-adjusting stick-look for controllers, brings about a few Hawk changes, adds a separate button for Draco's charge mechanic, and (finally!) autodetects XInput devices, allowing for the proper use of both LT and RT on a given controller. It also includes a handful of fixes. Thanks for playing! -- CHANGES:

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.
Static Clicklets are now "up-to-stick" instead of "down-to-slide". This means they default off, and only cause the user to stick if pressing Up - previously, they defaulted to on, only deactivating if the user pressed Down.
Force Resonator now has an interaction with Ace's Plasma Blender + Dracopent's Claw (increased Charge Rate).
FIXES:

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.
Fixed an issue causing Ace and Hawk's Resonating Oxjack Body effect to fail to reflect projectiles.
Fixed an issue allowing Vera and Quint Laser to let their powers combine. (Sorry!)
Fixed C. Beta and Boltdash spawning with Purist on.
Fixed Fortune Stabilizer spawning with Bankrupt on.

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.) -- CHANGES:

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.
FIXES:

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.

(That button should work properly again.) Thanks! -- Hi, folks! Patch 1.30.3 is now live.

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.

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.

20XX 1.30.1 Patch Notes -- July 13, 2018
Hello! Today's 20XX 1.31 patch fixes a bunch of bugs that 1.30 introduced. Thanks for playing! -- CHANGES: Added a Discord link (to our official Discord community) at the title screen. For now, this link only appears in English, but we'll change that very soon. Draco no longer do
Hello! Today's 20XX 1.31 patch fixes a bunch of bugs that 1.30 introduced. Thanks for playing! -- CHANGES:

Added a Discord link (to our official Discord community) at the title screen. For now, this link only appears in English, but we'll change that very soon.
Draco no longer double-dips with the Dracopent Helmet and Plasma Blender. (It still grants him a charge - it does not slow the rate of combo decay.)
Reduced Unstoppable Force's two-hit combo SFX.
Added a Quick Restart button in Seed Racer plays.
Added the DLC Availability button back to the title screen for Draco.
FIXES:

Save and Quit no longer forces the Unstoppable Hammer back into Draco's unwilling hands.
Fixed an issue causing Draco's Plasma Blender to ramp up too quickly.
Fixed an issue with Draco's Rippling Axe first swing.
Fixed an issue where Vika and Jest couldn't undevelop Core Augs. (I'm not sure why they'd want to, but hey, you do you.)
Fixed broken Advanced Options menu translations.
Removed an old debug trigger that somehow was causing folks trouble.
Removed some 1.3 Augs that shouldn't've been showing up with the Purist Skull active.
OUTSTANDING:

Draco's voice SFX are still really quiet.
