Live action game trailers are nothing new. It's an easy way for developers to tease their upcoming titles without having to reveal any actual graphics or gameplay. Recent examples of this include Resident Evil 5 and Halo 3: ODST.
So there's a new trailer out for Need for Speed: Hot Pursuit, the latest in the NFS series and the third Hot Pursuit title. However, this trailer comes with something special: a spectacular live action realisation of the chase from the E3 reveal trailer.
In the original trailer, we see an epic chase whereby a Koenigsegg CCX, Pagani Zonda Cinque and McLaren MP4-12C are pursued by two Ford Shelby GT500s, a Bugatti Veyron, a Lamborghini Murciélago and a Bell 206 helicopter. This is all realized (presumably) with the in-game engine and is pretty sweet in itself.
