Large and and small asteroids and alien "borg" spaceships are threatening the human species! As astro- or cosmonauts players are part of an intergalactic demolition squad. During four levels they have to blast away all threats to life on mother earth. The more enemy targets you hit, the higher your score and ranking become - from a private soldier up to a 4-star general. At the end of every round there's either a grand salvation ceremony or a scenario of utter destruction depending on whether the earth was saved or destroyed.

In addition, viewers and players can chat with other space pilots via text chat.
