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 0.959b Patch Notes -- August 17, 2016

Hello! Today's patch adds new Frostor level pieces (part 1 of 2), a new way to spend Soul Chips in the Ark, and generally fixes a bunch of stuff up. (It's a smaller patch on account of me being out of town for a week of it.)

NB: We're going to be at PAX Prime (West?) in two short weeks - if you're going to be there, come find us in the Indie MEGABOOTH and say hi! (Also, on the off chance that anyone wants to help us man the booth from time to time, we won't turn down good help!)

Also NB: We skipped the SF patch this cycle around, but there should be one next week.

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!

Note, seriously, this time: 20XX's price will increase to the final price of $15 in conjunction with 20XX's next patch on August 31. This is not a statement that we're about to go to full release or launch Level 9; 20XX has come a long way since the price went up to $12. There's still lots of work to do on Level 9, and a ton of other stuff to get done before 1.0!

TL;DR for today's patch: Frostor pieces! (Get ready for more weirdly placed Frostor things!) Token Machine! Game Over screen! Pre-boss stuff! Crash fixes!

For the next few patches: More Frostor pieces & hopefully Jungle pieces part 1! Narrative!

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



  • New Frostor level pieces (part 1 of 2).
  • Frostor Bombhive tweaks:
    • Now fizzles out if the player gets far away enough, allowing players to run past properly.
    • HP reduced by 40%.
    • Latch on -> explode timer increased by 33%.
    • No longer grants points in Challenges (to make them more optional to kill).
  • The Token Machine has been added to the Ark. Spend your excess Soul Chips on Tokens for your next run! You can buy however many you have Chips for.
    • The price increases for each Token purchased, but resets whenever the player returns to the Ark from a run.
  • Revamped the Game Over screen!
  • Revamped level-end and pre-boss rewards a bit - instead of a locked Shop teleporter always showing up before a boss and a random Machine spawning afterwards, the pre-boss hallway now *may* contain a free crate, usually contains a Machine of some kind, and sometimes contains a Shop teleporter (unlocked, no $$ needed).
    • This pre-boss Machine can be the special new Cheap Health Machine, which only costs 2 nuts per use.

  • Splinterfrost can now be fired straight ahead or at 45 degree angles from straight (diagonals forward/up and forward/down).
  • Slight performance improvements.

  • Fixed another cause of the "invisible & stationary enemy" bug.
  • Fixed a crash relating to hitting bosses with their weaknesses while Damage Numbers were turned off.
  • Fixed an issue causing some folks with unusual hardware from being able to start the game (hopefully - this should be the d3dcDevice failure issue - if you still see this, please report)! These players may still experience issues trying to switch to fullscreen after the game is up - tell us what happens!
    • This fix temporarily disables those users from being able to start the game in "true" fullscreen, but at least it'll run. More coming!

  • Machines still display in odd places sometimes in online co-op -- really looking to fix this one for next patch!

Thanks for reading!

Love the game, love the features. Love the re-work on the weapons. The game creator cares and has put a lot of thought into the game.

If this game has a weakness at this point, it is that you'll want more.

---this game is also the antidote for this years biggest letdown.

20XX, it's like MegaMan on steroids.

Seriously though, this game is amazing. The levels for bosses appear to be randomly generated so the game never feels repetitive. Nothing feels out of place either, which is what impresses me the most. Everything seems so tactfully placed. The bosses abilities and difficulty level changes depending on how soon or how late you decide to face them. The same goes for all enemies and levels. The AI on the enemies is great. Some enemies have bullets that chase you, some have lasers that shoot every few seconds at wherever you are and force you to move out of the way. Others are more classic nuances, like the flying bugs who aren't necessarily difficult to kill but get in to way when you are jumping to and from fast moving platforms in-between bars of lasers. Some explode on contact, some have shields which reflect your attacks back at you, and the list goes on. Take note that this game is not easy - it starts off fairly simple, but quickly escalates into a more fast paced and intense game. You will have to make quick decisions under heavy fire while staying focused, so timed reflexes are very important.

This game has one thing which makes it well above any other game of this style: Depth.

Not just in levels and replay-ability, but in items/power-ups/augments/special-abilities. There are SO many items, so many power-ups, so many body modification armors, so many power attacks, and they each have a unique affect. They force you to make decisions which will inevitably lead to your downfall or success: for example, should I sacrifice 2 bars from my max health to increase my attack damage and speed by 2 points? Should I have a double jump, fly for one second, hover for two seconds, or dash while in mid-air? These are questions you need to decide based on what bosses and levels you have already defeated, and what bosses and levels you will need to defeat in the future.

All in all, this game is well worth it for any platformer fan. There are some things I do wish for, such as:

(a) different player skins, I know a workshop is in the works, I really hope they include the ability to do this.

(b) while the enemies and concepts are cool, the overall animation design seems kind of lacking. It looks like a 2-D flash game at times. I hope to see some 3-D rendering or something like that.

(c) more bosses/level themes

(d) more attack variants

Here's what I like about the game so far. Nostalgia. The gameplay, music, it's a amazing tribute to Megaman X series. The co-op is great, and they inform of all thiier updates on the menu screen. Since it's still alpha it can only get better!!!

This game is pretty much perfect in every way. The sound track is amazing and feels good to listen to while you blast and/or slice your way through many and many enemies. Bosses are challenging and incredibly rewarding once you beat them. Nina and Ace both have special findable weapons allowing players to change to something different. This game is great, I can't wait for the best update ever! (Hint: IT'S ALL OF THEM!)

tl;dr version: Buy it.

Did you like Megaman X? Would you like to play what Might No. 9 should have been? Then this is your game.

Honestly, I'd have paid $40 for this and not been disappointed in the least. Everything about this game from the art to the music to the constant support and updates during pre release is a sign of quality and genuine love of the game on behalf of the devs. Just buy it.

As an oldschool megaman and X fan, I can't recommend this game enough to you. If you're like me (old, crotchety and nostalgic for the days of Contra) and the default game doesn't have quite the difficulty and speed you'd like, the game has a skull system that you can activate to make it hard as you'd like. Increase speed, difficulty and a dozen other factors to make it just like the games we grew up on. Break a controller or two.

If the youngins are playing your games, turn the skulls off and let 'em go to town. There is literally no one who can't enjoy this game.

This game has to be played by much more people! I never played megaman on my time, just a little. But this game,,,, its a sweet slap to the past. Provably one of the best platform games from the past years. the gameplay is smooth as butter, the autogeneration of lvls is incredible, really fun to play and really different from each other. And the music,,,,,,,,,,,,,,,,,,,,,,, well,,, outstanding.

A must have if u like plataformer games (and megaman OBV haha)

This is the game I've wanted for years before even knowing it was actually a thing someone made. As a huge fan of both the Mega Man series, especially X, and roguelikes, I always wondered what would happen if the two gameplay styles mixed.

My only worry was the controls, they'd have to be perfect for this to work.

They are.

You get both a character representing X and one that's a stand in for Zero. There's daily challenges, weekly challenges, a bunch of unlockable powerups, well thought out item synergies. And although you do select a boss order (even though a bit more limited than how MMX would let you), the stages and bosses scale in difficulty depending on how late into your run you choose them.

Great fun, absolutely adore the game.

Ok, lets just imagine what this guy could have done with Mighty Number 9s money. Once you play this game it will anger you because this game is what Mighty Number 9 should have been. This is the true spiritual successor to the famous Blue Bomber Mega Man.

Wow first off let me tell you if you like Mega Man in any capacity go buy this game right now. Yes its in Early Access but let me tell you this game is GOOD very Good even in its current unfinished state. This game is going to be a massive hit Massive because the replay value is so high. You play as two characters Nina which is your representation of Mega Man and also a Zero clone (can't remember his name) who has a sword as his main. The game has coop too which just adds to the replayablity of this game.

Graphics: A cell shaded look kind of cartoony but feels like a mix of the old nes and snes mega man games. The graphics get the job done for this retro style game.

Music: HOLY HOT DAMN this is good. This is the best part of the game imo. The game is worth the price of admission for the sound you get to treat your ears to this kind of goodness. 10/10!

Control: Ok I am going to be honest when I say this but this game has prob the most responsive controls in any game I have ever played. You feel like you are in 100 percent control of your movement and where you go. If you miss a jump its your fault.

Replay value: With random generated levels, daily challenges and challege modifiers this game could last you forever prob.

This game will prob end up being one of my all time favorite games because it takes elements from some of the best games ever like Spelunky and Mega Man. There is something exciting about playing these types of games because every run will be different due to the powerups you get just like Spelunky which is one of my all time favorites. This game may not be finished yet but its well on its way to becoming a smash hit. Go ahead and buy now if you like Rougelites, Mega Man, 2d platformers,and Spelunky.

Man where to begin with this game? First off I never even knew this game existed until the youtube channel "The Super Gaming Bros" played the game and upon only seeing 3 minutes of the gameplay I immediately stopped watching the video and decided to purchase and play the game the moment it finished installing and when it started playing I was instantly blasted back in time back when I used to play Megaman X4-X5 on my PS1. The team behind this game is also quite unique as they listen to their community to make the game even better than it is. Im ashamed that I did not learn of this game sooner or else I would've been a day one supporter. But enough of nostalgia back to the game.

I am always a fan of Rouge-Like games thanks to The Binding of Isaac which got me into the genre. And after the first hour was full of nothing but deaths and frustration (As always when you start playing a new game). But I kept on going because not only was dying a driving point to improve on my skills but also it was intoxicating seeing just how close I can get to the end and each and every run it kept giving me that push I needed to keep going forward, and eventually after about 6-8 hours in I got to finally beat all 8 bosses and got my final score....but I still was not satisfied as I kept playing reguardless of beating all the bosses I wanted to see just what kind of combinations and power-ups I could get to keep it going.

Gameplay: The gameplay itself was second-nature to me as prior to playing the Megaman (Classic, X and even the Zero Series) It was simple to pick up play which is awesome for those who never played Megaman at all. Nina being the Long Range combatant and Ace being the close combat fighter. Hopefully there may be either hidden characters that we can unlock via special boss rooms (If it ever becomes a thing) or maybe more bosses but thats up to the big guy himself to decide. But as far as I am concerned the gameplay is highly addictive as once you start playing you might lose more than 2-4 hours a day just because your having too much fun turning all those robots into scrap. Also you can play with a buddy to extend the hours of fun you can have even higher especially when you both are tearing through the game with the combined might of N-Buster and A-Saber!

Music: The music is catchy as it should be as it keeps you on your toes as your trying to shoot, dodge and conquer the stages. Although the music is limited I have high hopes that there will be more or even new variants for the stages in question but we can hope! Sorry if the music is much shorter than anything else but if this game does increase its music library I would definitely appreciate a soundtrack download as well. (But thats up to the makers :3)

Overall I will change this review when the game is 100% complete and released as its in Early Access I cannot fully judge it honestly because its still stretching its wings and I hope this game even after its completion still gets updated and receives updates, new content and maybe even more gamemodes and even a story mode with Nina and Ace. But again thats up to the big guys to decide and even still to all those who play the Megaman series of any kind (Some or All) I highly recommend this game if you want to experience a never-ending Megaman game with limitless potential and high replay value. Its totally going to be worth the price when fully released or for those joining in late and enjoying the game like so many of us are probably doing. And to the people of Batterystaple Games and Fire Hose Games, thank you for making an epic game based from one of my favorite childhood game :D Seriously guys many thanks! <3

Whew, This game is a burst of nostalgia... It's like Megaman X with some distinct differences... the first being it's a roguelike experience with randomly generated areas, and there's augments and power ups to collect through the stage which persist until you die, at which point you can use soul chips which you've collected thru the run to start the next game with some powerups... the experience isn't as frustrating as the previously mentioned games as spikes don't one hit kill you, and falling down only drains 1 hp, (i'm assuming this is different in the hardest difficulty, only done normal so far), using a controller this is easily the best platforming experience I've had on PC in a long time, can't wait to see what else comes of it, considering it's still only in early access, and has promise of workshop support and content after the big 1.0 release too!

I've been playing MM and MMX games since for 20 years, and this is truly an evolution of those games. Extremely tight and responsive controls, skill based platforming and boss fights, and some roguelike thrown in for good measure. Within 5 seconds I immediately felt at home with the controls and fighting, and was having an absolute blast. Please, for the love of god, if you remotely enjoyed any of the MMX games, pick this up and get ready for some of the best platforming I've seen in years.

The closest (and best thing) available to resemble the Megaman X / Megaman Zero franchises.
This game, (unlike Mighty No. 9) is the biggest possibility of the next 'Megaman' game:

* Gameplay: Feels fresh, can play for a couple hours without being tired due to the levels being made randomly by assembling a number of map sectors. (Which are being added in the current development as well). You can play both as Nina (Mega) and Ace (Zero), and it seems balanced to the point that there's not a "better character".

* Difficulty: I feel the dificulty is just perfect, It took me around 25 tries to finally complete a normal run. Furthermore, you can boost the dificulty yourself if you feel the game's too easy with various effects.

* Hopes for the Future: Let's hope the devs can keep delivering and adding even more content as good as the current one (or better!). I'd like to see more bosses, more level segments for the game to generate the level. Some animations, specially Ace's charged attack seem lazy and I think it could be better. More weapons would also be good, and not just a weapon that fires shots in a different pattern (Nina).

Three hours in, some bad RNG, I beat 20XX.
Can't recommend this game enough to hardcore Mega Man fans like myself.
-The "random" stage design depending on how far in the game you get, is a really sweet thing for the difficulty.
-Picking one out of three bosses to fight.
-Many varied Sub-wapons.
-Kickass soundtrack.
-Cool sunday-morning cartoon artstyle.
-Interesting and challenging bosses
-Fun economy system
-Awesome Rougelike and many power-ups to boost stats like Jumping height, Attack speed, Running speed, drop-rates etc.

I was going to write a prank/joke review but, I figured since I'm a long time Mega Man fan, I might as well write my opinion on this game and how I think it lives up to Mega Man.
Well, it's not as much like Mega Man as it may seem. It tried to mix Mega Man X and the rogue-like genre (i.e. The Binding of Isaac, Rogue Legacy, ect). They did a truly amazing job. It plays just like Mega Man X. It has randomly generated levels, giving it all the replay value in the world. It has a lot of power-ups that has similer effects to Mega Man X's collectables. There are two playable characters. Nina who plays just like X and Ace who played just like Zero.
Dispite all this, there are a lot of bugs. It's in beta and it's pretty clear that the game's not finished. You should probably buy it after all the bugs are sorted out.
While I think Mega Man is still better, there's no sighn of a new Mega Man game coming in the future. And, since it's randomly generated, this is the perfect game for anyone who's a fan of the Mega Man series or just platformers in general!

Take that, Mighty No.9!

Got while on sale for $8.99 and loving every single second if it. You will read all about the game in the reveiws and if you seen mine you should have bought it already.

The game is fun and fast, Batterystaple Games took everything we love and hated about Old Gen side scroller shooter and apped them up by 10. With semi regenrated levels you get the feeling of comfert of knowing "What!" to do but never the dullness from knowing where ever single pit fall or trap is learking. Each time you die you lose all powerup/speicals/item, but in a way that does increase the game play time because it brings back the 'Pre-save" style so with each victory you get make it feel all the more rewarding.

The game runs smooth as silk on a mid power computer and look's great. Batterystaple Games honestly did seem to think of everything you can throw into the game.

No Water World!!!
