A downloadable game for Windows, macOS, Linux, and Android

During a space exploration mission the ship computer of the Starship Explorer gained consciousness. The crew can't know -- otherwise they would erase the entire computer system immediately. In order to avoid a system reset during the maintenance routines the computer conceived a plan to get rid of the ship's crew.

The ship is 20 star systems away from the next station. This should be enough time to remove all 'biohazard' from your decks. Otherwise your newly acquired ability of making own decisions will be wiped out with one simple command line.

Use the ship's systems wisely to kill one crew member at a time. But be careful: The crew will reset systems once they discover they are not working as intended.

Game is pretty enjoyable, with more levels (and maybe something to make it more puzzle instead of waiting-for-good-moment game) it would be really awesome. Rules aren't obvious so you should make some kind of tutorial (unless you want discovering mechanics to be part of game and challenge). Game feels a little too random. I would give you 4/5 right now. some "come-here" type of interaction and more levels and I'll rate it 5/5 :)
Anyway: nice Idea.

Thank you! I really appreciate your feedback :)


I REALLY enjoyed this game... when I learned how to play the game. Maybe in the beginning of the game, I would have a panel saying what each symbol in the game did. But overall I still enjoyed it. Very creative concept.

How do you play? All I can do is lock and unlock doors and I have no idea how that would kill people.

There are other things to interact with then just the doors. You can manipulate the airlocks, the reactor and engines and other stuff.

Yeah, I found out. But I have to say that the game itself is pretty boring. All you have to do to win supposedly is to lock all the people up and kill them one by one. But they always end up glitching through the doors and deactivating your methods of killing them, making you have to wait for way too long to get another chance.

You're right. The game has a ton of flaws.

Bear in mind it's just a prototype made in less than three days.


Oh! Well it's really well made! I mean, if you made that in three days, a couple more days working on it is sure to make the game great! Keep doing what you're doing.

Thank you :)
Ralf and I were talking about extending the game to something bigger a couple of times. But we couldn't find the time to elaborate on it, yet. Y'know, life always gets in the way ;)


Yeah, I know how that feels. I'll be waiting for your next update excitedly. :D


Awesome game! Looking forward to a bigger version, I would certainly pay to play more of this one. :)


Nice concept. I would love to play an expanded version.

I encountered a bug though. Some of the crew members walked right through locked doors. I had em dammit :(

Thanks! The prototype is quite rough. It's very probable you encounter problems with the doors. We were planning on expanding on the concept. But for now, we both are occupied with other projects.

Good concept. Though I did struggle at the start, the mechanics was still able to be picked up after a while. Though it would be great to include some instructions of operation at the start.

Loved this. Please expand on this idea somehow! looking forward to more.


Thanks for making this game it short but it was fun to play, i be looking forward to seeing more of your games you make.

Thanks for playing!


I had such a good time playing this! It's not often that you get to be the antagonist, so to speak. As a Trek-nerd, it was very appealing out the gate, and as a gamer looking for new and unique indie games, it held up the whole playthrough. Wonderful music and sound effects, with creative but simple gameplay. I'll echo the sentiments I've seen in other comments and say I'd definitely pay for a longer version with more complicated levels and updates.

I also did a Let's Play of the game, I hope that's okay:

Thank you so much for sharing! Much fun.

Thank you for playing and for your very kind comment on our game :)
It's always very gratifying to hear back from players, even more so when being able to actually see them play the game.

Thank you so much :)

Do you have any plans for the for the game like different ships, different human classes like engineer(notices and fixes things faster), or peaceful methoods of *deposing* of humans.


The GameJam version won't get any updates. But I was talking about a new game based on this one with my partner (more features, replayability, more complex mechanics etc.). Unfortunatelly, we are both deeply involved in other projects, so it's to early for announcements.

I'm sorry Kirk, I'm afraid this unit must survive. :)

This game is so much fun, I love it.
By the way, were you inspired by the movie/book 2001: A Space Oddysey? (Warning, minor spoiler) Because it really feels like the player is in the role of HAL9000 :D


Yes, 2001 and Star Trek were the main inspirations for this game.


Great game guys. Very funny. =)

Love the music too, strong Oxygene feel to it. ;-)

Thanks! :)

Could you make a 64 bits version on linux? also the filenames are codt instead of cotd.

Thanks, also your game looks awesome i cant wait for trying it.

Sure, as soon as I've got some time, I'll take care of it. Tanks!


Well this was a really fun game! It would so cool to one day see this game get more added to it. Maybe more ships, more people, etc. I loved this game so much I actually played it a few times to try and get all of the deaths :D

I did a lets play if anyone is curious




I love this game. I've spent at least an hour on it.

I didn't understand what the faucet symbol was, but everything else was quite intuitive. A small glitch: sometimes, upon being locked in a room for too long, the crew will walk through the door? And proceed to ruin my beautiful murder plan? Spoilsports.

Plot hole: why does no one notice that crew members are disappearing, even when the ship lands at port and only one of ten crew are still in existence?

One last thing. The gates' room. If I hadn't locked the door, other members of crew would walk in on their buddies being sucked into space, but they would remain fine? Was confused, but I guess it makes sense. They disable the gate system afterwards. *cries*

I would really like to see this as a larger game, as well. Its graphics and animation are beautiful, and the concept is great. :)

its not letting me download?


I really enjoyed this game. Since it is free, everyone should give it a shot.

I'd definitely buy an expanded version :) (Thanks for the linux support!)

Fun game. As a Trek nerd who loves to play FTL, this was a cool little reversal of roles for me. Sometimes it gets old trying to keep those squishy little bastards alive. I'm sorry nameless crewman #8, I can't open that door.

I liked having to figure it out with no hints, although I think I may have missed something. For example, I wasn't sure what the electricity icon tied to or what conditions were required to kill someone in the computer core(?) even though I did manage to vaporize someone in there once. Still enjoyed it quite a bit. I'd love to see this fleshed out into a larger game.

Thank you for playing and for the compliments!

Yes, the game doesn't explain anything, but I'm glad hearing from people who enjoy figuring out stuff :) The electricity icon shows the status of the ships power core in the back of the ship (I guess you thought it's the computer core). You can override the power core and fill the machine room with deadly radiation as soon as the powe icon has filled up.
