This is a new fangled version of the classic asteroids game... well sort of. Ur mission is simple, shoot the beep out of any asteroids and alien space craft that gets near to u. If u dont, they will certainly want to destroy u... so best take them out first.
U have an auto fire laser canon that will be shooting like there is no tomorrow. But u also have some Plasma missiles u can launch during times of desperation. Watch out for power ups, they will come in handy and help u survive a little bit longer.
