Info

LOOK ALIVE SOLDIER! AND STAY THAT WAY!

There's been an "incident" at a government lab, some God-forsaken place called Black Mesa. It is imperative to National Security that no one learns what has happened there.

You and your squad must infiltrate the lab, eliminate the hostiles, neutralize all resistance and secure the facility. This is no cakewalk. You'll have to rely on your training and trust your fellow soldiers if you want to survive this mission. No one knows what you'll find there, but expect the worst.

So pack your gear, the chopper leaves in 15 minutes.

• Opposing Force's advanced AI allows you to lead a squad of military specialists.

• Explore never before seen areas of the Black Mesa Research Facility.

• Opposing Force contains all the incredible technology that made Half-Life the Game of the Year.

How-to-play On-line

The digital version requires the proprietary Steam client, which is not available on most platforms. The multi-player there works, but is incompatible with any other version. You need to port-forward 27015 (UDP) in order to host a server.

The original disc release is not playable. Several alternatives to WON.net existed, but they're varying in quality, up-time and most importantly player count. They're only an option if you're playing with friends.
