The Obscura Experiment
SteamAn 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…
Climb aboard the spaceship, and discover a state-of-the-art facility!

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

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

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