Here is a random vid. This is not there first one, but this is definitely by far the best one. Its from the series Arby & and Chief made by Machinima. If you would like to see more just look at similar vids. The only real one's are made by Machinima. There are a bunch of random and try to imitate them. So watch out for those noobs.
Arby & the Chief
Here is one of the most well developed Halo 3 montage that I have ever seen. I think this kid should get recon armour or at least a cookie for this cause this kids rape.
This video is AMAZING!!
