Good but not great.
The vehicles were a nice addition.
The action was deifinetly more intense.
The Single Player Campaign, while short, was better than previous installments.
The Cons: Your teammates are sometimes unresponsive to your orders. For example; your in the middle of a fire fight and order "Fire At Will" but Bravo team is swimming in the lake and can't find the shoreline.
The Single player mode was short and the difficulty doesn't pick up until the last few missions where I died more times than all the previous levels combined.
With the exception of the frustrating command responsiveness (or lack thereof) the game was alot of fun. But, unless you're getting it for the Multi-player option, I'd recommend renting it.
