A Weyland-Yutani research colony ceased contact in a remote South East archipelago chain, known only as the "Echo Region". Deemed unexpendable, the Company has sent in an elite search & rescue team from the U.S.C.M. They are to find and recover any and all remaining files and research documents, as well as rescue any of the remaining personnel... Noted, classified experimentations may have escaped containment, and must be exterminated.
