Aliens are attempting to take over our planet, and this means war! Galaxy X is a turn-based shooter, where the alien race of Groobs are attempting to save their kind by taking over another planet. Groob history has left their home planet in ruins, and leaving them no other option but to find a new home. Navigate your tank with the left and right arrows. Once you are in position change the trajectory of your turret with the up and down arrows. To fire, hold down the space bar until your power meter at the bottom shows you are at the "skull" level of adequate power, then release the space bar to launch your projectile.
