MarZ: Tactical Base Defense

MarZ: Tactical Base Defense is a strategy game about building a defense base on Mars and fighting off hordes of undead. Set in 2065, it follows humanity’s first arrivals on the red planet, where undead cosmonauts already live. You manage your crew and resources, defend the base and uncover the hidden history of Mars as you try to secure humanity’s future.

Defend your base

Enemies attack from all sides, so you must secure the fronts quickly. You can direct your crew to fight attackers or man towers and other buildings. Build a power grid, manage resources and use weapons and perks to shape the battlefield. The tech center and arms factory let you research new turrets and, if you survive long enough, super weapons.

Campaign and modes

The 20-mission story campaign has alternate endings. Skirmish mode lets you create custom, procedurally generated battles against successive waves of enemies, and also supports custom and campaign maps. Its Outbreak mode pits you against one immense zombie horde instead of multiple waves.

Research and customization

Research adds technology options and upgrades for all towers, including repair drones, mines, Tesla towers that can teleport zombies, mortars and prism lasers. The game has three difficulty modes, all rebalanced and updated based on player feedback.
