Let me put it this way. if you liked the close-quarter combat and highly destructive nature of BC2, you'll like this. If you also liked the huge, sprawling maps with tons vehicles like classic battlefield games(e.g BF2, 1942, Vietnam...etc.), you'll like this too. It looks like DICE is combining all the good elements from previous Battlefield games to Battlefield 3 and to me that's effin awesome.

There are some changes also both new and old. You can go prone like in previous Battlefield games except BC series. The squad system have been reworked, you can only spawn to your squad leader this time instead of any member of the squad. There are no regenerative health(al least in multiplayer) so you have to rely entirely on medpacks. A suppresion system have been in added which basically means that if you shoot in the general direction of an enemy soldier, his screen will blur and shake heavily screwing up their aim. It also works even with somebody hiding behind cover(I'm not sure about this one, that's what I heard). The class system is the same as the BC2 with few changes. This time we have: Assault, Support, Engineer and Recon. The medic class have merged to the assault class so you don't have to worry about enemy medics with fuckin' M60s shootin your ass. Like in BC, There are different playstyles to each class like gong back to assault, he can be a combat medic helping his teamates or an explosive expert I presume.

DICE still haven't revealed everything about MP so I hope this helps.

That sounds very awesome indeed so far, I don't know whether to be happy or disappointed with the medic merge, now we'll have assault douches running around throwing medpacks and noobtubing all over the place, although I think the change might be for the better, those fucking LMG were so overpowered.

Also like the way the health regeneration is gone, so people actually have to work as a squad in order to play the game, but I see it panning out this way - everyone going assault, camping somewhere and just throwing medpacks on the floor, after all the assault weapons I found the most accurate ones.
