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 ESTABLISIHMENTS 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 RECIEVING 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

Mod not working?
An update by Valve to some Source engines has caused a number of mods to stop working properly and give errors. Please visit my Get Mods Working post for more details.

    Just unzip the pack into opposing force folder (gearbox if i remenber right) then the mod should appear when opening custom mod. I played this one without the upgrade of opposing force ( back in 2004) and after 2/3 of the mod, i got stuck in front of a door that wouldn’t open (perhaps it’s working with the latest patch (i asked the author back then but he could help me since i was the only to report this bug)

    It was a fearly enjoyable pack

    Maybe?

    OK, got it working.
    Average mod. Fairly easy. Not much in the way of textures or interesting environments. Mostly grunts to kill, a few aliens. Grunts spawning in illogical places, and where they’re not needed. Good firefight at the end that you can prolong, before you escape. About 15-45 mins on skill 3. Worth the download.
