Mars Colony:Challenger

Mars Colony: Challenger launched on March 4, 2014 as a self-contained simulation game. The store description presents a complete, structured experience — three zones, seven phases per mission, and a defined progression system — with no mention of planned updates, expansions, or additional content. The only developer news post, from August 7, 2015, was a brief announcement celebrating the Greenlight approval of a separate sequel game (Mars Colony: Frontier) and offering a sale on Challenger. This post says nothing about future content for Challenger itself — it simply points players toward the new game. There are no DLC listings, no roadmap, no post-launch update announcements, and no developer communications of any kind after August 2015. The game appears to have launched as a finished product and received no post-launch content additions. HyperKat Games shifted their focus to the sequel rather than continuing to develop Challenger.
