COSMONAUT Wins an Award!!

"(...)you can feel the void of space, and it's right there in front of our eyes... it's terrifying (...)"

COSMONAUT is a highly immersive First-Person Space Simulator. It combines a non-linear narrative, realistic graphics and highly detailed simulation to produce a thrilling experience.

COSMONAUT is a game about survival, exploration and cunning. Everything around you can kill you, the suit can get torn from shrapnel, your visor can break from impacts. Your fuel, oxigen and suit power are limited, so you must find ways to replenish them. On the other hand, most things around you are usable, so you must explore the environment to find tools, supplies and clues to unravel the plot.

Current feature set:

  • Explorable environment outside and inside a space station (matches 1/6 of the space compound for the game)
  • Use of tools to interact with the world (hammer to break things, blowtorch to cut through)
  • Replenish of supplies can be done from O2 tanks, Fuel tanks and batteries or from the EMU chairs of fallen comrades.
  • Death Conditions: impacts on visor, lack of O2.
  • Handicaps: lack of fuel will leave you stranded, lack of power will disable your navigation and illumination systems. O2 reduction will start to blur out your vision.
  • NPCs
  • Non-linear story engine implemented


  • Oculus Rift support: we currently support Oculus DK2
  • Microsoft Kinect support: we currently support Kinect v2.

The game is currently under heavy development and will be released as an early access game, since we need some resources to fund the rest of the project.

Our plan is as follows:

  • Main plot line consists of 15 acts, all of them non-linear and interconnected.
  • We will first release what we are currently working on: gameplay testing environment with all the assets and features for the final game.
  • Then we will start releasing the various acts.
  • Early access players will get to have a say on features, plot and some other aspects. So all of you can be a part of this game!
  • The acts can be tweaked and tuned during early access.
  • We can add more acts to the story and even different arcs, it will depend on the feedback from players.

I LOVE the Linux support, keep it, please.

The immersion in the game just givesme the chills, it's like you know it's a game but you still get the spine chilling feeling of being alone and virtiually helpless in the emptiness of space. Keep up the good work guys!

I've checked Cosmonaut at Comic Con Portugal and it gave me the creeps! the immersivness and the vertigo were present all the way during the demo. I hope that i can play this game in its gold version asap! Great work guys, I wish Ground Control the best of luck!
