The old Hulkbusters headquarters. Originally a New Mexico base dedicated to the Hulk's capture and named Project Greenskin Base,^[1] it also could hold other gamma-powered superhumans. The base later relocated to Nevada, and was acquired by Operation: Zero Tolerance.

General Thaddeus E. "Thunderbolt" Ross was the orginal founder and leader of "Project Greenskin". The base was re-named Hulkbuster Base and Ross was eventually replaced by Colonel John J. Armbruster.^[2] Months later, Armbruster died in the line of duty. Hulkbuster Base was then given direction by S.H.I.E.L.D. and Clay Quartermain was assigned as its liason.^[3] Shortly thereafter, Hulkbuster Base was re-named Gamma Base.^[4]

Gamma Base became Ross' headquarters once more as the Red Hulk when he was recruited by Steve Rogers, who had replaced Norman Osborn. Gamma Base was staffed entirely by Life Model Decoys. One in particular, Annie, became very close to Ross.
