In 2065, humanity begins preparing Mars for colonization, only to find the planet already occupied by undead cosmonauts. You lead the defense of the new arrivals’ installations while investigating the hidden history behind the undead.
Build towers and support structures, establish a power grid, and manage resources to keep defenses running. Crew members can fight individual attackers or operate buildings and towers, so you must assign them where they are needed as enemies threaten multiple fronts.
Research unlocks new turrets, upgrades, perks, and eventually super weapons. A 20-mission campaign has alternate endings, while Skirmish offers customizable procedurally generated battles, including a mode with one enormous horde. The Marsform editor lets you create and share custom maps.
Players who enjoy the game often point to its hands-on mix of tower defense and base management: assigning crew, powering defenses, and balancing resources gives battles more to consider than simply placing turrets. Several also liked the campaign and the unusual Mars-and-undead setting. Other reviews describe the experience as repetitive or criticize its limited progression and demanding later challenges, so reactions to its long-term variety and difficulty differ.
