YouTube user and gamer JackFrags put together this pretty cool video using in-game footage from Dice’s Battlefield 3. It should be noted that while this is in-game footage, the situation isn’t live, raw footage from a server battle.
All of the users that you see in the video are placed actors. They were set up there by Frags to make this video. Machinma style movies and videos are always interesting to see but JackFrags’ “The Run” is also interesting.
