Take on Mars is leaving Early Access
Sometimes games stay in Early Access for a very long time and it seems they won’t ever be released. Some of them do leave it after three years, as it was with Take on Mars. After few years Bohemia Interactive announced final release, and, by the way, it took them much more time, than it is needed to reach Mars with current technology level.
Final Take on Mars version has a Robotics campaign, a Manned Mission story campaign, and sandbox survival multiplayer. Also, all in game is simulated, so you will need all your skill to achieve goals. You can also create new content, thanks to modding support, or just take a look at other players works.
You can grab the Take on Mars from Steam.
