Personaly, i would rather have Halo...AND I DONT EVEN LIKE HALO
You start with a tazer stick thing, and some sort of machine gun (which has an awesome secondary fire) - for some reason you only start with one magazine for this weapon...what sort of soilder boards an enemy ship with one clip?!?!. Anyway, as you progress through the mission you have to perform little tsks such as jumping from crate to crate and crawling through vents, which isn to bad, but the fact that a dam shotgun at close range takes 2 shots to kill somebody is just plain annoying - also tells you how realistic it is.
The graphics are basic everyday xbox graphics, and the sound isnt anything mindblowing. There is good features to this game though, the amount of weapons you have to choose from is a pretty varied, all the weapons have secondary fires (i found all secondary fires entertaining - probably the best part of the game) and well, thats all i can think of.
the worst thing about this game has to be the dam control layout, having "y" as the action button is one thing, but having R3 for the crouch button is just sick, this is the first game ive ever come across where the crouch is R3 instead of L3, was the control layout guy working with a mirror or something?.
What im getting down to is that this is an ok sci-fi shooters, but i got bored with it very quickly. If your looking for a good sci-fi shooter look no further than halo, because this game only deserves to be rented, it shouldnt have the privilage of being bought (all that money spent on it is just a waste)
