Here are the some Fallout Avatars you can use for your Profile Picture on NGU :p I know Wondoh had done this with Black Ops 2, but all credits to that guy. Had the idea first and I give him props. Since I don't know if he does it anymore. Here is the Fallout Avatars you can use for your Forum Avatar.
Special thanks to Tustin for making the BO3 Avatars as presets in the Avatar Section <3 !
Just released Advanced Warfare/BO3/Destiny Avatars as well! Go check them out if you would like to.
