The sound track is solid but no where near as good as the previous game and the sound effects seem to be recycled from the last game as well.
Pretty much exactly the same as the last game, Which is disappointing considering it was released over a year later. The visuals are a bit more defined in this game but it's nothing to go crazy about. Far less bugs and glitches though, That's a plus.
Simplified and far less complicated than the previous game, Which is a huge plus in my opinion. Vehicle controls still suck.
Shorter campaign. Not much in terms of exploration in this game. No replay value. Collectibles require a lot more effort to get and that's very annoying. Far more fun to play with a friend then by yourself. Too straight forward, I really wish they had offer the same amount of exploration they did in the first game in this game.
Slightly improved due to the more defined graphics and simplified game play. However, It really lacks content and replay value and that really sucks because that's what made the first game so like-able.
