Mars Colony: Challenger
July 29, 2015 - WilloWhisp

Hello fellow Martians! Over the past year, work has been going on developing the sequel to Mars Colony: Challenger. Mars Colony: Frontier is currently up for voting on Steam Greenlight! Taking community feedback, we started from the ground up to redefine the Mars experience. All new and improved visuals, base building, career paths, dynamic economy system, and much more have been implemented, expanding on the concepts put forth in Challenger.
Upon release we will be doing discounts on Frontier for all of our loyal fans of Challenger. Thank you so much for playing our game, and if you enjoyed Challenger, wait until you see the Frontier!
