Recently, the full version of Reentry A Space Flight Simulator was released on Steam. The project has been developed under the "early access" program.
Reentry is positioned as a realistic space flight simulator based on NASA programs and which "strives to find a middle ground between a simulator and a video game."
You create a new astronaut, gain levels and experience for every action, completing missions in space. You will have access to both missions similar to those that occurred in real life, and fictional ones designed to challenge you as an astronaut. Control almost every system like real astronauts, watch the sunset and sunrise, orbiting the Earth at a speed of over 7 thousand meters per second. Explore the surface of the Earth and Moon, or just enjoy the solitude in space.
Reviews of Reentry A Space Flight Simulator on Steam are "overwhelmingly positive", with a rating of 96%.
