They wanted to create "BOW's" or rather "Bio-Weapons." For what though? A new army? Maybe a terrorist attack to take over a country of their interest? What was the true meaning for these experiments? Whatever the reason was, it is long gone, and there is no turning back.

Only George Trevor, the architect of the Spencer Mansion, and Ozwell E. Spencer, owner of the mansion and creator of Umbrella Inc., knew about the traps and hidden areas of the estate. With Trevor out of the picture, only Spencer would know.

Trevor realized that there were areas that would not built by him or his crew. Something wasn't right... As well as his families disappearance, Trevor knew something was up.

However the T-Virus got loose was irrelevant now. The teams working in the Spencer Estate lab where now all infected. All experiments were loose and roaming the Arkly Mountains.

Was the outbreak due to S.T.A.R.S. ranking officer Albert Wesker? Quite possibly. He was the one who indeed wanted to create the BIO-WEAPON of them all, Tyrant.

Experience the horror for yourself.
