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 release version of 20XX will have lots more content and cool features -- more level variations, more powers, more pickups, more ways for your buddy to accidentally bump into a spike and die, etc.

Some design choices have and will continue to change over the EA period based on fan feedback.”

What is the current state of the Early Access version?

“It's nearly feature complete. 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?

“Yes. While we're in Early Access, we'll be selling 20XX at a reduced rate so that the game's worth what you're paying for it at the time. As we approach full release, we'll slowly increase the price.”

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 0.963b Patch Notes - October 12, 2016

Hello! Today's 20XX patch adds Steam Cloud support, some boss tweaks, polishes up the UI, adds a new enemy death effect, and more!

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: Boss tweaks! Steam Cloud! UI stuff! Enemy bits!

For the next few patches: Lategame health balancing! Skytemple work! More UI stuff! Oxjack fixes! OXJACK FIXES! (Hopefully also some performance work - some online play seems to have slowed down in a way we're not comfortable with, but haven't had time to fix yet.)

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



  • Steam Cloud! 20XX now stores your save data and transfers it via the magic of clouds.
    • If you want to back up your data on a specific device before cloud syncing (in case you have multiple machines with different save data), copy the stuff from My Documents/20XX/ before launching the game.
  • Perforator and Vile Visage have both been tweaked and have new attacks.
  • VV's weird "weak point" mechanic has been removed, and replaced by an additional attack phase. His health has been reduced accordingly, and his interaction with his weakness Power is now somewhat different.
  • Lotus' cycle time is now up a little, giving Ace a little more time to get in for damage safely.
  • All enemies now break into pieces when slain.
  • Earlygame bosses are now less likely to crumble into dust when lightly poked.
    • A long time ago, we added HP reduction to the game's first three bosses, figuring that the road up to 4 should be relatively smooth.
    • In hindsight, this was bad.
    • Really bad.
    • The end result was that all our early bosses felt too easy, even to first time players - so we've removed it. The factors were 50%, 65%, and 82.5%, so compared to pre-patch, the first three bosses now have 2.0x, 1.54x, and 1.21x their previous health, respectively.

  • Lots of UI tweaks. The shape of the main HUD element is more compact, P2 is now right below P1, Tokens display differently, and the Bonus Timer finally has its own UI element.
  • Slot Machines rebalanced a bit - more tokens will drop, but there's now a chance you'll get nothing (making it a little more gamble-y). Overall, item yield has gone up a little bit, and it's more likely you'll be able to interact with a Slot Machine when you find one.
  • Eternal Star can now be Level 1 (in addition to Kur). Half bugfix, half small change.
  • The Bonus Chest now has a visual that matches the new Bonus Timer.

  • Fixed the Boomerang Blade not being fireable down-and-right on keyboard.
  • Fixed Lotus not moving properly in netplay.


Thanks for reading!

20XX 0.962b Patch Notes - September 28, 2016

Hello! Today's 20XX patch reworks the Lotus Boss, adds in the new and old DATALORE system, makes some character tweaks, and more!

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: Lotus Boss redo! DATALORE! Character tweaks! A million fixes!

For the next few patches: Probably a lot of UI polish! More narrative stuff! More boss tweaks!

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



  • New Death Lotus! It's a very different fight now.
  • DATALORE rides again! All your favorite items (and also the ones you hate) are now proudly displayed and expounded upon in the DATALORE menu (accessible from the Pause screen).
  • Boss durability changes:
    • Ace's combos now delay boss iframes, so the frames start at the end of his combo (not the start).
    • Ace's attacks now trigger longer iframes versus bosses.
  • Character tweaks:
    • Ace and Nina's tiny differences have been flattened out. We don't think they really added a whole lot, and mostly just got a little confusing. So:
    • Ace's starting health and base attack damage are now 8 and +0 (down from 10 and +2).
    • Nina's starting Power damage is now +0 (down from +2).
    • The base damage on Ace's weapons have been raised by about 20% -- some a little more, some a little less -- to counteract the base attack damage change. His initial combo damage is still 12-12-20, but his attacks now scale better.
  • For both of the above sets of reasons, boss health has come down slightly across the board.

  • Combat Repros now properly target Frostor Bombhives.
  • Armor gain, in general, has been nerfed a bit. Stuff that grants armor just plain grants too much.
    • Crates that used to contain two armor capsules (4 armor) now contain one (2 armor).
    • Armor Bloom now grants 6 armor (down from 10).
    • Enemy armor droprates unaffected.
    • Armorspreader unaffected.
    • Armor Nut armor-on-nut-pickup chance reduced by 33%.
  • The level 1 boss chest no longer always provides a giant health shower.
  • All boss chests now provide slightly less energy.
  • Rollster Beta tweaks:
    • (All versions) now have slight angular variance on their bounce attacks.
    • Fixes for Endless & Undying scaling for Rollster Minis.
    • Boomerang Blade attacks now spin up slightly to his side, and grow into existence before rolling on along. They don't do damage until they're all grown up.
    • Fixed an issue causing Rollster Beta to be a little sticky on walls he ought to bounce right off of. (bugfix)
  • The Pickup Display now comes down from the top in Boss Rooms.
  • Slot Machines now spit out their bounties closer to the ground, and use the space they're in a little more efficiently.
  • Splinterfrost's up/down angled firing now only requires holding up or down, instead of up+forward or down+forward.
  • Violence Enhancer (Prototype) now grants bonuses equal to your current bonuses, clamped in the 5-10 range. (Picking up VE when you have more than 5 Attack or Power damage now gives a bigger boost.)

  • Leaving the game no longer resets your One-run Shop.
  • Fixed Endless hazard scaling (it was double dipping with the old Endless hazard scaling).
  • Fixed Endless scaling also applying to health gains. (ooops!)
  • Fixed some bugs relating to using the Ark token machine and quitting/reloading the Ark before starting a run.
  • Shatterbeak's Ice Blocks no longer hang around after he dies sometimes.
  • Fixed some wonkiness involved with holding up and down and firing Vera.
  • When unlocking or one-run buying the Meganut, players can no longer change characters to have the +25 nuts applied over and over.
  • A whole bunch more.

  • Some players using XBox One controllers are finding their inputs borked -- RT doesn't work, can't attack, etc. It's caused by a Microsoft-made change. We still don't officially support XBone controllers, but we're looking to fix this for next patch anyway - in the meantime, please use joy2key, xpadder, or similar software to emulate keyboard functionality with your controller. You can also unbind LT, which should do the trick as a workaround.

Thanks for reading!

Steam needs a "Maybe" recommendation. This is being written from the perspective of a longtime Megaman player, take that for what you will.

While I enjoy the game very much and find it plenty fun as of the time of writing this, at the same time it feels somewhat unpolished in some areas, especially the visual style, which is...strange. It's kind of like Flash animation or Spine in that it mostly uses bones rather than frame-by-frame or pixel art. It's not bad by any means, but to my tastes it feels somewhat cheap-looking and placeholder-y, especially in some of the character designs. While the human characters look fine enough, the bosses and main playable characters look almost TOO cartoonish.

It becomes an issue however when the screen is either too busy with bloom and projectiles that blend into the environment, or when what you think you see does not actually have the desired result. I also feel like my hitboxes aren't as reliable with this style of art.

For example, I was playing with the "Not-Zero" character Ace, who had a spear attack that gave him incredibly long ranged attacks. However, this attack would phase through walls, yet more often than not wouldn't actually hit things on the other side. I say more often than not, because sometimes it actually did hit, but it didn't feel like there was any consistency.

The balance is also somewhat mixed as well, but mostly leaning on the "too easy" side. Perhaps I'm spoiled by marathoning Megaman Zero recently and feel like anything else is "too easy". But some of the powerups you can get really upset the balance. Huge chunks of levels can be skipped by getting a lot of jump height and speed upgrades, or the hover ability.

Bosses in the end only require you to spam your attacks at them, as they don't have much in the way of mercy invincibility. Some bosses are well designed, while others are somewhat annoying; it's really just a mixed bag and it can vary depending on your experience with games of this style. There are other minor issues as well, such as charging being a bit too fast, and Ace not really having any cooldown between his slash combos.

Another gripe is the lack of a story outside of the intro cutscene, which really isn't much to work with. It's just an excuse to set up the game and give you a vague understanding of why you're a super fighting robot fighting other super fighting robots...or something. I really don't know.

As with any Early Access game however, you're taking a major risk if the game doesn't have a demo. I enjoyed what I got but find it too early and unpolished in certain areas to pay full price for, even if the price right now isn't final. I would much rather purchase the game on sale or in a more finished state at the price it's at right now. But, at the same time, it's not a bad game by any means; far from it. It's fun, it's a proper Megaman X game, and it does just enough with it's roguelike elements to be considered unique from that. So if that's what you want, go right for it.

The fact that somebody remembers Megaman X, and megaman in general makes me wanna cry tears of joy.

The soundtrack is more of a Megaman era soundtrack, and lesser of that to Megaman X.

This game is a play on megaman x's gameplay, with roguelite elements.


This is what mighty number nine wanted to be, except this is based upon Megaman X, and not Megaman.

thats even better


megaman x's games

are better

So, so, SO good. I was an early backer for Mighty No9 from the beginning. What we got was akin to childish trash. This game though? 20XX? PHENOMENAL. So much love has gone into this game that it clearly shows. The music, artwork and style, gameplay...all heavily inspired yet refreshingly new and original at the same time. Unlock abilities to help you on the way, play with other players, and much more in a very roguelite way. All this and it's EA. Amazing. This is one game I'm proud to support.

If you're looking for a new Mega Man game, or a new roguelike, or a new action platformer -- look no further!

20XX is a very strong platformer, a very strong rogue like, and incredibly a very strong Mega Man game! Each time I sit down with the game, it feels like I'm getting further and further into the game. The bosses are varied, but have a repeatable / learned strategy. The art is indicitive of what I liked about Mega Man games, and hits better in some places (very strong enemy, environment, weapon art) and worse in others (some weapon particle effects are a bit rough, but nothing abhorrent). Overall I have had a ton of fun with the game, and would highly recommend it. Also, I'm something of a baby when it comes to Mega Man games in general, and while I fair decently, I still very much appreciate the different difficulty levels, and daily/weekly challenges both.

It's mostly fun, I'll admit, but it's not in my library because of a few issues.
The biggest issue being (sigh...) the Rogue-like application to Mega-Man not working.
The whole combination works out like a mustard and cocktail sauce condiment for your sandwich.

It's not a bad combination for some, but it obviously appeals to those who can handle the weird and aqquired taste. (and I can't vouch for that analogy, as I'm not willing to take that risk with the sandwiches that I make.)

Within the main series games of Megaman, be it the classic series or the X series, you get to choose which bosses you battle, and therefore, what powers you get from said bosses, by traversing through their stages that have specific enemy placement.

Having enemies placed on a single narrow platform isn't a dealbreaker for most, but it is annoying, and it's something you're bound to see a lot of throughout the game.

It could just be me though, because I honestly don't have any experience with Megaman games to begin with...

First and foremost, I suck at writing reviews.

About 20XX: It is the MegaMan game I have been wanting for some time. I loved MegaMan but found the repeated levels and formula boring after some time. Unlike MegaMan, you won't be able to remember the proper enemy patterns, where the perfect pickups are, etc. But what you do have is some well made platforming mixed with the right amount of "Rogue-lite" tendencies.

It is never fair to compare games to others, but I find that is when my reviews are most beneficial: If you take Mega Man X and Rogue Legacy, get them drunk and make a wondreful beautiful child, you get 20XX

The hardest thing to believe is that this game is "in beta." It feels very complete.

This is probably one of my favorite Early Access titles. It's a perfect time killer. If you love Mega Man, get this. Don't keep reading this review. Get the game. Don't go get that Mighty No. 9 garbage, you will regret your life for the rest of your life. This game is a blast, constantly being updated aswell.

10/10 One of my personal favorites.

Plays Like MegaMan X

I Saw It Was A MegaMan X Clone And I Bought It

If There's 1 Thing I Regret About Buying 20XX Is Not Buying It Sooner ;)
It May Be Slightly Buggy. But I Can Forgive It. It's In BETA. Give It A Try And A Break

I may come across in this review as a little harsh, especially considering I've only played it for barely 2 hours. At the moment, though, it was all I needed.

From a personal standpoint, as a longtime MegaMan fan I was skeptical about getting this game in the first place, knowing it was a Roguelike experience and not personally finding an interest in a MegaMan game turned Roguelike.

Then a friend gifted it to me on steam so I guess I had no choice but to try it out!

Dying several times without ever getting to the 3rd boss after multiple tries in a single night's marathon of gametime was about enough for me.

To be fair... the game is actually pretty neat. I kinda wanna like it. But at the same time it suffers from an aggravating case of "I Wanna Be The Guy" syndrome. Characters start out with very little health and health pickups are either rare, or cost 3 bolts apiece. Also, each health pickup only restores 1 health and bolts themselves are also rare, gauranteeing you'll never be able to buy more than 3 or 4 per stage anyway...

At the moment I've stopped playing. I intend to come back to it later when I can put up with the frustration, and try to judge it on mid-to-lategame merits as well, but a review is not necessarily invalid simply because it only considers the earlygame. That is the face of your game, the first thing people are going to see. If you fail to get your foot in the door at that stage you often won't get another shot.

It's not fair but it's true, and something all developers must earnestly consider.

That's not to say this game is BAD because of it. Consider this review more of a... "It wasn't for me" kind of thing.

If you're also the kind of person who finds fault with this kind of thing it might not be for you, either.

Do you like Megaman X, but wish it was more like Binding of Isaac? Then this game is for you. The controls are as tight as you remember them, and the items are a ton of fun. Once you get high levels of speed and jump, you could argue it almost feels better! This game has a lot of potential to be great!

That being said, it does need more variety in the item department. I also don't like the way they scale bosses (add random hazaards in the room), but I can't wait to get home and play another run each day.

This game is awesome. If you loved Mega Man, Metroid, or any other old school platformer this is your game. Rouge-like elements combined with smooth responsive controls and great graphics. Tons of gamemodes and runs to do. This game has multiplayer,... MULTIPLAYER!! so awesome.. Overall even if the devs did no more work on this game at all I would reccommed buying it.

!!One side note: DO not try and play this on a keyboard. You really really need a controller. If you do not use a xbox controller, remap the buttons right away and enjoy!

10/10 Overall.
