(Capcom's primary storyline)
The Metal Industries Corporation (Metal Industries CO.) was a company which developed metallic materials for various commercial products. It was contracted by the Umbrella Corporation a number of times, and was an important-enough customer that samples of development material were offered for customer review.
In 1998, they succeeded in developing TG-01, a metal alloy that was designed to fool metal detectors. Intending to sell it as a successor material in weapons manufacture, its Development Planning Chief - Carl Redhill - had a sample transported to the Umbrella facilities on Rockfort Island for review.
