they all look different becasue they have aged. and i have heard many theories about how to get the DG2. like shooting the car batteries in the main spawn with the 90sec death machines etc... i just think it would be cool if there was a way to get it only through an easter egg, to reward us for all the work we do to find all the eggs, lol. and i find it strange that: Tank is holding the DG2, Richtofen is holding the Thunder Gun, Takeo is holding Winters Howl, and Nikolai is holding the Ray Gun. You would of figured that each person would have the weapon that their home country developed. USA- winters howl Japan- ray gun? GER- DG-2
Russia- Thundergun.
