It’s mostly things from other trailers, but still. The new Battlefield 3 trailer takes all of the gameplay moments from the previous Fault Line trailers and puts them together and adds in a few more parts to give you (slightly less than) twelve minutes of awesome, awesome gameplay.
The attention to detail they’ve put into it is insane. Two special crawling animations, cool alterations to the HUD when certain events happen, destructible environments (even better than Battlefield: Bad Company 2‘s), and even shells falling from machine guns, so many details that really add to the overall visual fidelity of the game are in there.
The trailer can be viewed at EA’s Battlefield 3 site here. It’s more than worth watching to the end. If you haven’t seen the last few trailers, it’ll blow you away.
