generic stereotype but what do u expect from dumb ass like chosen one
No. It's a specific title based on "scientically measurable principle."
In this case, FNG; Fucking New Guy. Probably less than a week playing. EVERYONE'S an FNG at one point. That's cool.
Noob; Someone, like the Khans for example, that never bothered to learn how to play. They just bot out in Redding, buy some shit condition armor/miniguns, then pop in on whatever eno they can find and blast bluesuited slavers, junkers, etc or camp out Klamath.
