Environment Concept Director Volodymyr Donchenko set up a fantastic interactive concept art project called Alien Moon in Unreal Engine. Inspired by "iconic movies and games," it offers a first-person view of a dark space station.
If you liked Frictional Games' SOMA, you'll enjoy this one: there seems to be no one alive around except for you and monsters. You can watch Donchenko explore the environments filled with custom 3D models and downloaded assets in the video above.
