Justin (Saber Scorpion) returns with a bevy of new custom minifigures from Fallout 3. I've posted his Brotherhood of Steel figures here, but he has several factions on display - Vault Dwellers, Raiders, and Super Mutants.
Justin utilizes his decals to great effect, decals that you can purchase at his store. If you would like to see all of the custom factions, you can find them on Flickr and his website.
