Anyone who likes Half-Life 2 and similar games would do well to try this game. If you like the movies(Pitch Black and Riddick), you'll definitely like this game.
I found it a refreshing game. I didn't like it as much as Half-Life 2, but I liked it better than F.E.A.R. and Doom 3 (even though it is a bit difficult to compare those games to each oterh).
Give it a try, you won't regret it.
I can wholeheartedly recommend it as well. Really enjoyed playing this one through.
Very atmospheric. Vin Diesel voicing the main character makes it feel like one of the movies.
I liked the way you could play it stealthily. Shoot out all the lights, and use your eye-shine (Riddick's see-in-the-dark ability) to creep up on unsuspecting victims and shiv them. :ph34r:
It kind of ends up playing like a cross between a full-on FPS and something like Splinter Cell.
