On Mars - Alien Invasion (French)

On Mars: Alien Invasion is the long-awaited, somewhat co-op expansion to Vital Lacerda's best-selling and top-rated on Mars base game. Although this expansion was originally intended to be named Surviving Mars, Eagle-Gryphon Games made the decision to change the name to On Mars: Alien Invasion to better reflect the theme and content of this expansion. The narrative of the game is contained in four chapters of a story written by Nathan Morse. The gameplay contains four new and different ways to expand and play the base game. You will play one against many; completely cooperative; and even solo if you want, depending on the chapter. Included are four fresh, fully replayable ways to establish colonies on Mars!

For example, here is the narrative that opens the first chapter and sets the stage for all of the following action:

alert! Sensors indicate that aliens are invading the famous red planet! Conspiracy theorists have predicted this for a long time. The threat to your mission is too great; you must act. Will you be able to prevent the infectious spread of these beings who are bent on expanding to all habitable planets in the galaxy? Or will you play for the other side, a species trying to establish a colony on Mars, blithely unaware of the danger of their expansion, unaware that there are others out there who seek to keep humans "where they are." belong” on Earth.
