Mars: War Logs is a role-playing game set on the red planet of Mars. It has been nearly a century since the planet and its people were cast into chaos by a cataclysmic event. Player takes on the role of Roy Temperance, recently taken prisoner by the corporation Abundance. As Roy the player must navigate through the on-going struggle on Mars between feuding companies for the control of the most important resource on Mars after the cataclysm: water. As he makes his way through this struggle he must make several important choices that will not only define himself, but define the future of Mars as well.
The gameplay consists of a tactical real-time combat system similar to that of the developer's previous role-playing game Of Orcs and Men that lets you tailor the way you fight your foes by choosing to emphasize melee, ranged combat, stealth or perhaps the powerful Technomants powers. The game also features recruitable companions and a system for crafting armor and weapons.
