Galaxy X is one of the Shooting Games that you can play on UGameZone.com for free. The game begins when the Groobs, an alien race are seeking a new planet to live in. The human race doesn't like that and do everything they can to defend their world. Each tank has its own unique weapons and can switch between normal and special attack mode. You can use several supportive items, such as extra damage or heal to help your battle. Move your tank and use the right angle to deal more damage. Have fun!
