At GDC 2015, an impressive technological demo called Earthlight will be publicly shown that recreates the International Space Station and the environment of low Earth orbit with a level of realism that will delight fans of realistic space themes.
The video is really impressive and shows, once again, the power of Unreal Engine 4. At the moment there is hardly any information about this demo, except that they will show it at the GDC with an Oculus Rift and Kinect 2. It seems that its creators intend to turn it into a first-person exploration game in which the player will take on the role of an astronaut from the International Space Station.
