Those keen-eyed newshawks at VG247 have spotted seven minutes of Battlefield 3 footage posted on YouTube, via BF3Blog. It's a leak, and EA will surely stamp on it faster than an elephant doing a do-si-do, so look below as fast as your fingers can carry you.
Wow this game looks OMGx10. The first portion is the same level I played at E3 this year. But then goes beyond what we were allowed to see. It's worth noting that it would very much be in EA's interests to leave this seven minute advert online. It's not exactly going to do them any harm.
You can see approximately 80,000,000 screenshots from the footage over here.
