I love the series, story, guns, and game play of the first 2 but this has almost nothing to do with them. Keeping away from spoilers, they kill too many story characters. It locked up on me once and the last battle had to be played twice because the AI died just before ending movie kicked in. Game play was ok but without all the stuff I love from the others, I was not impressed. All my favorite guns were taken out and you play as new characters.
Really that's all there is to say. Do you just want to shoot stuff then here ya go. The story and characters are bland, the aggro system is basically effectively gone, and you spend the whole game killing the same handful of generic dudes. Really there is not much else to say.
