Metroman has left for a superhero convention and has left you his sidekick Vectorboy in charge of the city. In only a few hours after Metroman leaves for the convention the city is invaded by aliens and its up to you Vectorboy to save the city. Defend the city and stay alive by collecting powerups and increasing your combo meter in this action packed Defense/SHMUP.
Use the arrow keys to move M to mute Z to shoot and P to pause. The more enemies you kill the higher your combo meter increases, the better chances to get power ups, and the wider your laser gets.
