17TH SEPTEMBER 20–
MESSAGE FOR: AGENT SHEPHERD, ADRIAN
WE AT THE UNIT ARE GLAD YOU DECIDED TO JOIN US, RATHER THEN SPENT A FEW MORE MONTHS IN CONFINMENT. YOUR MISSION, WHICH YOU WILL ACCEPT, IS TO INFILTRATE THE BASE OF THE TERRORIST ORGANIZATION KNOWN AS ‘DOUBLE HELIX’.

THEY HAVE BEEN LINKED TO A NUMBER OF RECENT THEFTS AND SABOTAGE OPERATIONS IN SCIENTIFIC ESTABLISHMENTS ACROSS AMERICA. MOST RECENTLY, THE ORGANIZATION KIDNAPPED 5 OF THE WORLDS TOP GENETIC RESEARCHERS. YOU MUST RETRIEVE THESE SCIENTISTS WITH DUE HASTE.

BE WARNED, THE ORGANIZATION IS A VERITABLE ARMY THAT BEEN RECEIVING FUNDING FROM SOME UNKNOWN BENEFACTOR FOR SOME TIME NOW. FURTHERMORE, WE BELIEVE THE GROUP HAVE BEEN CONDUCTING A NUMBER OF ILLEGAL GENETIC MUTATION EXPERIMENTS. YOU MUST STOP THESE IF YOU CAN.

AFTER YOU HAVE INFILTRATED THE FACILITY, BACKUP FORCES WILL ENTER THE REAR ENTRANCE OF THE BASE AND RENDEZVOUS WITH YOU. GOOD LUCK, YOU’LL NEED IT.

OFFICE OF THE ADMINISTRATOR,
THE OMEGA UNIT

Is this mod's story supposed to be independent from Opposing Force and Half-Life?
