"Did you bring your gambling money? Well $60 is all you need for an enriched content filled game!"
Pro: New weapons and equipment are always a plus, AI enemy is pretty smart, and have dialogues, the AI enemy also have some cool intimidating masks, storyline was great once again, turrets are an awesome addition both single player and multiplayer, your mouth moves when you talk both in single and multiplayer modes, and the several different ways to enter a room or go about doing your buisness is uncountable.
Cons: Friendly AI is still dumb as dirt and they die way too much, and the glitch to get unlimated XP in the first mission is really really really....well (lets be sensitive) cheat oriented.
Overall: Buy it. If your a fan of the serious, or first timer, I recommend it. You will have plenty to do, a solid pretty long single player campaign, and a never ending fun, uprgrading multiplayer are at your disposal. So go spend your money on Rainbow SIx Vegas 2, not crack kids!
