It's a blast. I rented it from Blockbuster a week ago. The fully destruct able environment makes for a really interesting raid, and it really is helpful when some noob is camping in a corner... just blow up the corner.
When you join a match you get put into a squad of 4, and you can spawn on anybody in your squad as long as they're alive. The problem is... you dont get to choose who you spawn onto, so the trick is to stick together and devise a plan... it really is helpful when attacking a base, to have a spawnpoint 2 feet away. There's another downfall though... alot of people in the game are lonewolves, and they just go wherever they want to, which is minus one person in the squad.
You can only talk to the people in your squad too, so if they dont have mic's, you're out of luck.
As far as the gameplay goes, there are plenty vehicles to drive around and blow stuff up in, including an artillery gun which can pretty much destroy a base in just a few minutes.
The great thing about the game, is that there are no "command posts" like in the other battlefield games. There is strictly one base with two targets in them... destroy the two targets and you capture that base, while the enemy gets a new one. You're either defending or attacking.
This leads to very intense battles, with EVERYBODY, not just a few people on a map that is miles long.
I loved the game, plus the campaign was hilarious.
