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 0.955b Patch Notes -- June 22, 2016

Hello! Today's 20XX patch changes the way Repros stack, adds a shiny new font, renames Soul Nuts to Soul Chips (rip), and a bunch of other smaller stuff.

Superfriends: Build coming with Arach's replacement 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: The closer we get to release, the closer the price will get to our planned Full Release price of $15.

TL;DR for today's patch: Repro stacking! New font! New Icons!

For the next few patches: Level design work, boss work (Arach's going on vacation!), narrative work!

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



  • Damaging Repros (Bat, Peng, Turret, Dragonface) now level up when you collect more than one, instead of giving you two of the same kind.
  • Minimechs (floaty guardian Repros) now stack up to 8 (down from infinite). Further pickups instead give 25 nuts. (Having 8 is functionally the same as having 100 anyway, just without the performance hit.)
  • Lots of changes and tweaks to Frostor/Skytemple level pieces.
  • New in-game font!
  • Soul Nuts are now Soul Chips. RIP, Soul Nuts. (Two kinds of nuts ended up being super confusing for new players.)
  • Mortar now ignores shields. (You'll see why next patch, but we're also moving toward Powers having more utility in general.)

  • Pop-up text for basic pickups (health, energy, etc) no longer shows up once you've unlocked a few things in the Shop.
  • Sharply reduced the damage Eternal Star takes from Force Nova's chain attacks.
  • Several new icons!
  • Health Machines no longer show up for any reason with Famine active.
  • Fixed up Kur's hitbox some.
  • Nina's Star Beam now properly allows 3 bursts on screen by default (down from a broken 4).
  • Eternal Star will no longer fly out of his arena as he sees fit.

  • The Furor skull is now much more Furor-ious. (Further tweaks may be needed here.)
  • The roughest Flapps now have a proper coloring (instead of just being confusingly also green).
  • Be Swift! challenges now properly despawn when failed.
  • Juiced Shadespurs now orient properly.
  • Hopefully fixed a goofy issue causing some machines/level-end teleporters to display/collide incorrectly as the client in online co-op.
  • Fixed an issue where killing the Lunar Astral first could cause their beamlink to persist invisibly until their next teleport.

  • (still) Some minor cosmetic issues with the new Lock icon. (Sometimes it doesn't display on Shop Teleporters when it should.)

Thanks for reading!

20XX 0.8 -> 0.954 Update Summary


  • Brand-new boss fights and enemies!
  • Tons of new items!
  • Core Augmentations (Core Augs, aka CAs) have been added to the game!
    • Core Augs affect one of your character's Core Systems -- Body, Head, Arms, and Legs -- granting powerful new abilities.
    • You can see your current Core Augs both in the Pause screen and visually on your character.
    • Each Core Aug is exclusive with other Augs in its slot, and each Core Aug belongs to a set.
    • Core Augs can be mixed and matched with Augs from other sets, but they truly shine when you find a complete set. See what happens!
    • Core Augs (currently) do not need to be unlocked, and are awarded in Challenge Rooms (always) and Shop Rooms (sometimes).
  • Challenge Rooms! These rooms optionally spawn as level midpoints. Three waves of enemies stand between you and the door! Each Challenge Room also comes with a bonus Challenge condition. If you achieve it, you'll get a bonus gold chest!
  • Added Prototype rooms! Discover their glory -- but at what cost?
  • New item class: Repros! Repros have realized the error of their ways, and want to help you out. Some murder your enemies, some protect you from harm, and some do special, awesome stuff. There are 8 kinds - catch 'em all!
  • Massive art updates!
  • Massive game performance updates!
  • Netcode stability enhancements!
  • Smarter level design!
  • Better Challenge scoring and Weekly Challenges!

Thanks for reading!

A ridiculously fun mix of all the best stuff from Binding of Issac, Risk of Rain, and Megaman. Having fairly little experience with the Mm series, it was pretty easy to start getting fairly decent runs after a couple of tries. It's really intuitive, the items are all noticeable, and there's a lot of content even in it's early stages here.

I was very hestiant about the rogue-like elements (not typically my cup of tea) but I took a chance on it and I'm very glad I did. It's super fun, the movement and attack mechanics feel great, the power-ups are varied and the game has a good sense of humor. Highly addictive, highly replayable, and highly recommended.

It's a great homage to the Mega Man X series. I'm hoping they add some end-game content as once you beat the 8 bosses, the game is over.

♥♥♥♥♥♥ off at ♥♥♥♥♥♥♥ Inafune for screwing everyone over with Four million dollars down the drain #9?? Do you want a good Megaman clone that's actually respectful to the source material and fun to play? Wanna give Inafune a big fat middle finger?? Play this game instead. It's definitely not a perfect game, but pretty damn enjoyable for the price. HIRE THESE PEOPLE CAPCOM!!

One of the best Megaman X games of all time!

OK, so confession time: I pirated this game. Yeah, I wanted to check it out. And no regrets. I was so impressed and had so much fun, I bought it. It's cheap and totally worth the price. Though the version I got was an older one, so first time seeing the current version surprised me how much it improved.

20XX is a fantastic Megaman X clone. Fast paced, fluid gameplay, cool weapons, nice level design with randomization. It's a rogue-like game. One life, no continues. Though the player can unlock cool stuffs that can be collected later for further progress.
First time seeing the game I was kind mixed with the visuals, maybe I'm still a little bit but it grown on me. Yeah I prefer pixelart or quality 3D graphics. It's high resolution 2D with fluid, skeletal animation.
The game can be tough, but it's so addictive!

Well, not in a mood to write a long review, I have a mighty issue right now.

-Fluid animations
-Pretty good visuals
-Very catchy, old-school soundtrack!
-Cool items, lots of variety!
-Semi-randomized levels (there are pre-created sets that make up a whole level)
-Pretty good boss fights
-Good learning curve, can be brutal after a while

-I would prefer pixelart more (not really a con, personal preference)
-Sometimes it's cruel!
-Some bosses are not that interesting
-There are some graphical / sound design changes from 0.80 that I don't like, preferred the older one.

To be honest, no more bad things come to my mind.

In conclusion: if your are a Megaman X fan, buy this game! It's seriously that good. I'm not even sure I had this much fun with an official Megaman X game. Buy this, and flush that Mighty No.2.

In its current state it's a strong 9 out of 10!

Kinda a weird world we live in when the fan, indie re-imagining of Mega/Rockman X with rogue like elements, in early access is better than the official 4 million dollar, 4 years in development, already finished Re-imagining of Mega/Rockman

This game..........THIS GAME IS AWSOME!

You want a game thats like Megaman X PLAY THIS!

Ok serious time!

-Classic Megaman X'ish game play. Not exactly Megaman X but in my option this game is better then any of the X games[granted I have only played X 1 and 2]

-SO. MANY. POWER UPS! With how many power ups there are in this game you are gonna have a very diffrent experience everytime you play.

-Two playable characters. And one is not clearly better then the other, they have diffrent weapons but they get the same power ups, so its just a choice if you like shooting or cutting ♥♥♥♥ more.

-It gives you a fair challange.*Stares intently at Mighty No.9* After playing Mighty No.SH!T im happy to play a Megaman style game with a fair challange, not to hard not to easy......ALSO THERE IS NO BULLSH!T WHICH IS GOOD!

-Game runs great. I have a ♥♥♥♥♥♥ laptop and this game runs 60 FPS. THAT IS RARE FOR ME SO THSI GAME IS CLEARLY MADE TO RUN ON ANYTHING!



-..........Nope, cant think of any this game is fricking awsome, this is one of the few games I have played where I dont thing one thing is good, this is a pretty soild game all around, im suprised this is in early access, if this isnt the final product im hyped as hell to see what it will be.

Final Point: BUY THE ♥♥♥♥ OUTA THIS GAME!

This game is absolutely fantastic. Everything about it, from the characters, the enemies, the bosses, and the soundtrack just ooses megaman x.

Every single run through of the game is a wild ride and it does a fantastic job of making the levels harder and harder as you go, as well as the bosses. Remember that boss you fought first last time that was a total push over? Well now he isn't, he has extra moves he didn't have last time or maybe even a second form.

The game is also very challeneging. Sure you might be able to beat 2 or 3 levels very easily but to beat all 8 bosses is quite the challenege. If it's too hard play easy mode which allows you to choose some extra power ups to start with. Too easy? Play one of the daily/ weekly challenge modes or enable some of the optional "skulls" which change the mechanics of the game (think halo skulls).

The more I play this game the better it gets. Every update has just added more and more polish and variety and I can't think of a single thing to complain about.

20XX is a game that replaces the Megaman formula's meticulous level design with a random number generator. Somehow, it works.

This is a game inspired QUITE heavily by the Mega Man X series to the point where veterans will be able to master the game's controls within seconds. A multitude of game mechanics return directly, such as charging shots, dashing (and dash jumping), wall jumping up individual walls, boss weapons, and many of the upgrades from the original games.

However, 20XX does display some discipline when taking elements, removing or modifying gimmicks that induce frustration (such as blunting spikes and bottomless pits to a single point of damage as punishment) and adding several common roguelike mechanics.

By action-roguelike standards, 20XX does pull its punches, and the success of a run is not as reliant on RNG as its compatriots. It does suffer from the common action-roguelike problem of creating difficulty through bullet hell-type enemy attack patterns, but in a normal run, bullet density will never become outright ludicrous (as it does in Rogue Legacy) and there is still some emphasis on reacting to attack patterns rather than painstakingly threading the protagonist through holes in a sea of projectiles.

The character progression in an individual run is excellent. In addition to raw damage/health/energy numbers increasing, items can be collected to increase jump height/movement speed, add special aerial maneuevers, and drastically change the behavior of standard attacks. Progression is significant enough that starting a new run after getting fairly far can be quite jarring, as one gradually becomes accustomed to the increased agility and utility one gains as one moves farther into a run.

As of this review, the game is still in early-access, and there are some small flaws and glitches to be encountered. Unlike most Early-Access titles, I would recommend the game in its current state, as the price is planned to increase until release and the game is quite enjoyable as it is.

I always loved Megaman as a kid. (I especially liked playing as Zero in the X games). As an adult, I've grown to have a fondness for roguelikes. This game is exactly what you might expect from that mash-up. Randomly generated Megaman levels. It has a bit of a Megaman 7, in that there are item shops.

I realized rather late that I had apparently missed the Kickstarter code distribution. Didn't have high hopes given my other two Kickstarter mistakes, but I sent the dev a message asking about the key I theoretically was supposed to have gotten anyway. Got a cheery message and a code within ten minutes, late in the evening. Instantly a fan of the dev.

Then I actually played the game, and I can't recommend it enough to any Megaman X fans. It scratches the Megaman itch in the same way Axiom Verge scratches the Metroid itch: It's not QUITE the same, but unlike many other classically inspired games, I can easily see myself matching my MMX playtime with 20XX.

This game is really the best of the modern platformer "roguelites" I've yet to play! The only things I'd want would be an ability to turn off some upgrades, for the Axe to be reballanced again... other little things like that. If you like the Mega Man X series, this is amazing.

I will likely update this once I get a chance to try out the local coop with my fiancee :)

I can't quite fully get into this game. It is for people that like Megaman X/Megaman type games obviously... but this game is a little too insane for my tastes. the hit sprites for the enemies and attacks are so huge, that hit detection isn't quite perfect. There were plenty of times I was trying to avoid a big fireball or enemy, and then I jumped forward - and thought I would take damage, but didn't because the hitbox of everything isn't the entire sprite. You eventually get a feel for it and can compensate, but I really think that if you visually touch a sprite border, you should take damage.

Also, I think because of the nature of the random levels, it relies too much on cheap hits from huge groups of weak enemies and environment hazards. I much prefer more thought out levels created by real people - like the Megaman games. It just feels more fluid and challenging on a fair level, as opposed to a bunch of thrown together hazards. I feel like they need to tweak the level generation process to allow for some more cohesive levelsthat don't have pit drops and environment hazards constantly.

All that being said, I don't hate it - and I can enjoy it to a small degree. My biggest complaint is there is no real feeling of progression overall. I think it would do well to add something like usable energy tanks, and maybe a few items that hold over even after dying (if even only for a few runs after instead of forever.) So far it's super frustrating to be having an excellent run, then getting screwed by a bad level or a crazy difficult boss, then to start literally over from the beginning with no nuts, and your base abilities.

Also, the few music tracks are pretty good - but they need a LOT more. They get repetitive much quicker than Megaman music does for sure.

Lastly, I feel like the main characters still need a slight redesign. They look kind of cheap to me. Something is missing, but I can't quite put my finger on it.

I'm glad it's still early access, which means they can hopefully polish some of this into a more enjoyable game. As it is, I find myself screaming after every death and have to turn it off for a few hours before I feel like subjecting myself to it again.

I recommend it to anyone wanting a good Megaman type shooter, at the $8.99 price I got it at. At this point though, I wouldn't be able to justify it's $11.99 early access price, and definitely not the $15 release price it will be.
