don't even bother with it
edit: it was brought to my attention that some feel my review unfair. i thought "y'know i was kinda harsh on it, i'll give it another shot" and to my credit i've played it twice more and both of those times were mostly filled with blinding fury at being shot through walls by virtually everything, not actually being able to go that many places "oh look i can surely climb that ladder... really? super awesome nano suit super soldier can't climb that ladder?" and being instaspotted the moment you uncloak. i guess my last complaint is the magically appearing soldiers. im not sure if the enemies are supposed to have nano suits like me, but if they are then that wasn't explained very well as i've had enemies pop directly in front of me.
long story short : i stand by my original score.
