Mysterious Space was originally created for the 2014 7-Day Rogue-Like competition, but has received many updates since! It features many familiar rogue-like elements - including potions, equipment, and procedurally-generated worlds - but is ultimately a side-scrolling action shooter.

26 January - small bugfix release

such a small release, I'll just post all the changes right here:

  • Shields were blocking damage that was supposed to go directly to your hull. This has been fixed.
  • The word "Shield" (whatever it is in your language) is no longer drawn below the bonus shield meter.
  • When Alien Teleporters granted invulnerability, they were only doing so for 1/60th as long as they should. This has been fixed.

  • When you have tons of fuel, the fuel is now squished together, so that it doesn't overlap with the shield/armor/hull/accessory UI.

20 January

pretty-big update: 0.11.0

the full changelog is available at but as always, here's a summary:

the largest change is the removal of "entropy" effects on equipment. I found, through playing with friends, that an equipment with an "entropic" modifier was almost guaranteed to be ignored by players. some of the entropy effects WERE too extreme, to be sure, but even when they weren't, the attitude towards them seemed to be "why take on a weird negative just to get a slight stat boost?"

SO: I removed all traces of "entropy" from the game! it took a lot of time, thinking, and effort to add all those effects, and it felt kind of painful to undo all that previous work, but I tried to remember one of my favorite quotes, by Antoine de Saint-Exupéry: "Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away." (and I'm sure I could apply that philosophy much more than I do!)

to be clear, "static" effects still remain. I also took this opportunity to tweak a few "stasis" modifiers, mainly by making more of them increase in power with additional stacks of stasis.

other, smaller changes, include:
  • I added parallax background terrain on several types of planets, for extra visual "ooh!" and "aah!"
  • there are a couple new achievements! (and I also took the time to create graphics for almost all of the existing achievements! (finally!))
  • when visiting a civilization, or the source of the mysterious signal, you now ALWAYS gain the fuel required to travel (instead of only gaining that fuel when you wouldn't otherwise have enough)
  • the visual effect of "scrambled sensors" has been completely redone, using pixel shaders (I've also put pixel shaders to use in subtler places, such as the blinking effect of enemies when they take damage)

thanks for reading, and thanks for playing!

good luck, pilot!

About This Game

Originally made for 7DRL 2014, Mysterious Space tasks you with delving deep into the ZZ-Omega sector to recover an important piece of information, and to return with that information in one piece.

To get there, you'll have to stop at planets along the way to find much-needed fuel.

Arm yourself with procedurally-generated weapons, armors, and shields to defeat the enemies that stand in your way.


  • Local co-op, up to five players
  • Procedurally-generated planets, including forest worlds, desert worlds, ice worlds, lava worlds, and others
  • "Alien Artifacts" and "Advanced Technology", analogous to the potions and scrolls of rogue-likes: does the Red Alien Artifact repair armor this game? Or will it scramble your sensors for 10 seconds?
  • Unlockable ships and ship upgrades
  • Procedurally-generated weapons, shields, armor, and accessories to equip yourself with
  • Various enemies and mini-bosses, with distinct movement patterns/AI
  • "Secret logs" that reveal the lore of the world (galaxy? universe?)
  • Supports XBox-compatible gamepads (you'll need them for co-op!)

Mysterious Space's soundtrack - by DDRKirby(ISQ) - is available for listening and purchasing at bandcamp:

System Requirements
