Save Earth from waves of alien attackers in this action packed space shooter. Use the Proteus mecha armor to save Earth from waves of alien attackers. The alien fleet is vast and diverse: 16 attack waves, 11 different enemy ships from scouts to gunships. Huge Boss Battles could halt your advance into the heart of the enemy fleet, learn their attack pattern and attack their weak spot with everything you have. Use the powerups: shields, power weapons, and drone weapons pods to inflict maximum damage on the alien fleet.
