Alarm: sensors indicate that aliens have attacked the red planet!

As you began to establish the first colony on Mars, you discovered that you were not alone in the galaxy… and that you were not welcome anywhere but Earth. Play the familiar role of a human civilization reaching Mars, or the opposing side fighting to prevent the spread of these creatures from infecting every habitable planet in the galaxy!

The Mars: Alien Invasion is a somewhat cooperative add-on to the game The Mars. This box contains four chapters of Nathan Morse's story, and each chapter allows you to play the game designed by Vital Lacerda in a different way. You can play against everyone; in a fully cooperative manner; and even solo if you want, depending on the chapter. Four fresh and replayable ways to build colonies on Mars!
