In the far future, earth was destroyed by an asteroid. It is up to you and the last spaceship to colonize a planet by surviving 15 days of alien attacks until the planet is terraformed.

Upgrade your weapons and hull, after every wave and survive as long as you can until the planet you have chosen is terraformed and you win the game.

Spend only an essential amount of money for your upgrades and don't let your biodomes get destroyed.
