First up is a fun MW3 montage created by JT24418, titled Best Montage EU, ever.
The second video again is from JT24418, but this time it's the first of hopefully many commmentary videos based on Fallout: New Vegas.
Third and by no means least is a video showcasing how troll The Scrub can be whilst playing MW3. The title of this video is "Why won't the flags go down?" Which says all that needs to be said.
