Call of Duty 4 Modern Warfare
Uses Omas' G-36 skin, all his. I used it as a base for the orange transparent magazine commonly found on most G-36's using a 30-round magazine.
Here's my favorite skin for the G36c to date - it's the same shade of gray as K&K's USC and UMP carbines, and as usual, has their logo. The clear mag was changed out for a solid one (real).
This skin makes the G36c to have white stripes.
Hibana's G36 Camo Skinpack, 15 different skins with pictures for each one included in download file.
This G36c has the same body color as the custom versions really available. It wouldn't be complete without H&K's logo right on the side in their shade of red.
