Don't know if I can believe it (We Deadly and Bloody were very 1999-topical),but Mac said in an interview in 1999 that he made WW3 BEFORE Shell Shocked...
I definitley believe it. He has verses from WWIII on some of his features from '97-'99. A whole song from WWIII appears on "I'm Bout It" with a different beat "Lockdown". His verse from "What Cha Mean" also appears on "Bloody", but with some changes.
