18 years ago, an alien invasion left Earth in shambles. Shortly after the aliens departed, the surviving humans joined together to begin rebuilding their civilization on the ground, while simultaneously constructing a new fortress in the sky. The military also began training new soldiers as quickly and cheaply as possible to prepare for future enemy attacks. You are currently enrolled in the Express Training Program, so you must fight to complete your training before you're ready to confront any enemies. Arm yourself with powerful weapons and destroy the enemy scum to move on to the next level and save the Earth in this fun shooting game!
