NEWWEST:
Pre-order skins
Halo 4 Pre-order skin coloring
I will try to get more videos out as more skins and armor are announced. I made several threads dedicated to all these seperate aspects of the game but I figured I would compile all of them into a single thread. If you guys and gals want to see more photoshop customization this is the thread that I will continue to update with skins and all of that fun jazz. Thanks for your time.
