In Captain Galactic, you are Spike Mopp, a science student whose lab experiment gave him special powers. Your job is to stop an alien invasion as Captain Galactic! You will be rescuing robots and other creatures while you make your way from planet to planet using your mouse to shoot yourself like a slingshot. Use the meters at the bottom of the screen to see how much power you have and what direction you'll fling yourself into. You need to rescue people and take them to your ship before the clock runs out. Keep unlocking missions and saving the galaxy in Captain Galactic!
