A Great game
The Graphics were smooth and even though there's a lot of enemies on-screen towards the end of objective it doesn't lag which is always a big plus.
i've noticed people complaining about the variety of the power-ups...did you even bother to pwoer all the way up...there is rockets there, they fire like the normal weapon but it's variety.
i think this is a good solid game, i would've liked to have seen more variety in the enemies (like that cell enemy).
For the first in it's series it's a brilliant game though.
