I think it's one of the best games of last year. I played through it 4 or 5 times. The final section is manageable if you know what you're doing. I consider it the best choice of the bunch but... you know, whatever. I already have it.
I honestly don't think I had any other weapon besides the pistol when I played it. Maybe that helps. I learned from the first game. Choose your weapon purchases wisely, because it'll be taking ammo drops away from the weapons you actually use.
