Pros: DX10 Graphics and EAX 5.0 sound. It sucks you in big time. Loads of atmosphere and the weapons to match. One of the best set of levels I have ever played, from a visual standpoint. You feel you want to keep playing because you want to understand this world. Good voices and music.
Cons: As an FPS it seems a bit gimmicky with the tricks and spells and what not, and it always feels like you have low ammo. I could not help but just resort to throwing objects and corpses at enemies by the game's end. Combat just feels so freaken random, I prefer FEAR in terms of combat. Last boss should have been more creative. In game physics only animates at 25 fps, so objects look like they move laggy even if your fps is 60.
Conclusion: If a game was released that contained FEAR's combat in Bioshock's levels, the game would be perfect 10 in my book. As it stands now I still recommend Bioshock because it's got good levels and story (with an insane plot twist involving 3 words), and that makes you forgive the somewhat disappointing combat.
