Different in a good way, reviews saying the conrtols suck obviously have not played RE4.

When I first started this game i was expecting it to look crappy, play crappy nd sound crappy. But I was pleasantly suprised by the Hazy Atmosphere and the controls. This game does add a sort of "live: element to it with the game, the way it bobs behind the character, kind of reminds me of GRAW for 360, And it adds some realis. I also liked the RE4 Style controls. You have to take your time, and use cover, you cant just run in there like an idiot (another GRAW element) I also liked the way the enemies limp or react when you shoot them in certain places. If there are alarge group of guys coming after you, shoot them in the legs first to buy some time and then shoot them in the Head (another RE4 element). The drug trading too is also entertaining, Knowing when to buy, and when you buy Crack at $700 and sell it for $1000 each it feels good.

Overall the game seems to have a high quality atmosphere (except for the "Diee **** that gets repetitve. And if you enjoy shooting game in general it should be fun. If you've played RE4 the control scheme should be right at home for you.
