About The Obscura Experiment

An experiment has gone wrong, and the whole complex is failing. Your only chance at survival is to use the various tools at your disposal to escape this now-hostile environment. But beware: an unrelenting force lurks in the shadows…

Play as Priya Ellis, a scientist whose research team has been decimated by a mysterious new form of life - the Dark Matter - which is invisible to the naked eye. Thanks to your scanner tablet and the ships' built-in surveillance system, you can outsmart the roaming menace by carefully planning your next move. But, keep an eye on your scanner’s energy: an empty battery would only guarantee your demise! Locking the doors behind you and luring the Dark Matter to energy sources comes at a high risk, but it could buy you some time…

Explore a Hi-Tech environment!


Climb aboard the spaceship, and discover a state-of-the-art facility!

Challenge the unknown, fight the darkness!


Come face-to-face with an unseen menace; push back the obscurity with your wits!

Observe, Plan & Execute!


Familiarize yourself with your surroundings, develop a strategy, and put your plan into action!

Investigate the events & uncover the truth!


Figure out what happened onboard, and discover the true motivations of Anabasis & Co.!

✦ AI summary

Players praise this free horror game for its creepy atmosphere, solid sound design, voice acting, and interesting premise similar to Alien Isolation, with most finding it worthwhile for the price. Common complaints include the short length (30-45 minutes), frustrating mechanics like poor battery life on the tablet and limited running stamina, awkward camera angles that reduce visibility, confusing level design, and some technical issues like broken achievements and a goofy antagonist design that undermines the tension.

A relatively short “Alien Isolation” clone, that you should definitely check out.

First run took me ~40 minutes, I have 100%-ed it by now, but I needed a certain guide here on Steam to get some of them, because some of the achievements are borked with the current version for some reason. Beyond that, though, I think it's a perfectly okay game, considering that it's free. I don't completely agree with the criticisms regarding the battery life of the tablet, to be honest, I had it run out only once, and that was in my later achievement hunting runs. In my first run and even on my deathless Dark Matter run, I had no issues with the tablet. At least a *little* bit more visibility would've been nice, though, especially in the crophouse. It's a bit awkward having your camera forced somewhere so that you can see something, and you just end up not actually seeing what's happening because you're conserving your limited resources and it's almost pitch black. Pro tip: If you know you're going to die, you can just reload last checkpoint instead of restarting the whole game and you can still get the deathless achievement. Just make sure you do it before you see the mission failed screen.
