These are alternate skins for the warthog and cyborg. 
To install, Use HMT (Halo Map tool) to exchange with the existing skins.
I used the Program GIMP to make the skins. Its Kinda like a free version of Photo Shop
You may chanage/alter them if you would like.
Note: the cyborg was made mostly by someone else, I just altered the body a bit.

If u want some more skins or any questions, you can email me at:
