it's pretty fun. i went in the game not knowing what to expect (i didn't know it was based on a comic book until i read the review). but the review intrigued me, so i got it.
the storyline is good, it really drew me in nicely at the beginning.
the darkness powers seem a little overpowered to me. i tend to rely on them more than actual weapons, which could be the reason for their strength. but the powers aren't too overpowering where they make the game ridiculously easy, which is nice.
the thing that grabbed me the most is the graphics. the environments look really nice. it's pretty neat to be able to go by a tv and change the channel. i think i read somewhere that there are actual movies playing on tv, not just the clips of movies. haven't taken the time to check yet.
the loading screens are a nice change from other games too. they're comprised of the main character talking a little bit about his past and himself.
if you're a fan of first person shooters blended with some sci-fi, i think you'll enjoy it.
