Ascent The Space Game
Over 270 trillion star systems are supposed to be present in the space simulation. The focus of this game is clearly on exploration. However, the game has much more to offer. In addition to obligatory asteroid mining, players can build their own space stations or ships.
Planets can be colonized through a complex process. Considerations must include gravity, radiation, temperature, and atmosphere. At the beginning, players must build a dome to adjust these factors enough to ensure survival. Once this is achieved, further structures can be built. For example, mining or agriculture become possible.
The game is already available in Early Access, and a demo is also offered on the homepage.
