It would be a shame to build a game around an environmental destruction engine and then not put it to good use. Fortunately, if this trailer is any indication, that's exactly what Battlefield: Bad Company 2 is not doing.
The video you see above is the recently-unveiled trailer for Battlefield: Bad Company 2's "Squad Rush" mode, a gametype designed around short, sweet, and bloody matches, pitting two four-player squads against each other. Rounds of Squad Rush are intended to be fast and furious, as evidenced by the above video - which also happens to show lots and lots of wonderful environmental destruction. Mmm, environmental destruction.
The delicious blowing up of bunkers and huts and homes and anything else with walls and a roof isn't limited to Squad Rush alone, but the close-quarters combat really does seem to encourage it. It's a good thing, too, because Squad Rush will actually come as a timed GameStop preorder exclusive for the 360 and PS3 versions in North America - preorder the game, play Squad Rush a bit, wait a month before everyone else gets Squad Rush so you actually have a pool of players to play Squad Rush against. On the PC, though, it'll be unlocked from the start.
It seems slightly odd to be restricting an entire gametype to just people who preorder the game at a certain store, but that's what EA is doing. I liked the Battlefield 1943 method better myself, guys. Can't we go back to that?
