About Alien Marauder
Alien Marauder is a science-fiction survival RTS set in 2672. After Earth’s resources are depleted, human expeditions search the universe for new life and encounter the Vexan invasion, drawing humanity into war with the Vexan swarm. You build and manage a base, develop its technology and population, grow an army and defend the base and its surroundings against attacks from all sides until the Vexans are destroyed.
Build and defend

Sudden or fierce attacks from the Vexan swarm make it necessary to keep developing your defenses and plan how to fight back. The game supports battles with up to 100,000 combat units on screen at once, as you counter tens of thousands of Vexans with strategic planning and attacks. Different situations offer varied strategic combinations and more than one way to win.
