Half-Life: Opposing Force is an expansion pack for Valve Software's science fiction first-person shooter video game Half-Life. The game was developed by Gearbox Software and published by Sierra Entertainment on November 1, 1999. Opposing Force is the first expansion for Half-Life and was first announced in April 1999. Randy Pitchford, the lead designer on the game, later noted that he believed Gearbox was selected to develop Opposing Force because Valve wanted to concentrate on their future projects. Over the course of development, Gearbox brought in a variety of outside talent from other areas of the video games industry to help bolster various aspects of design. Opposing Force returns to the same setting as Half-Life, but instead portrays the events from the perspective of a U.S. Marine, one of the enemy characters in the original game. The player character, Adrian Shephard.

Hello again everyone.

This has all been so overwhelming, the reaction to my work has much more incredible than I could ever have anticipated.

My intention was to make something that would reflect what Half-Life meant to me - the horror, the comedy, the action, and the realism of the world around you. Half-Life and it's many community made mods have stuck with me my entire life since I was young and changed the way I looked at games. A lot of the feedback from you all so far seems to show that I might have made some other people remember the same feelings Half-Life brought us when it was first released.

You are all brilliant. All the feedback, videos, reviews, comments have all meant the world to me. Thank you. I dabbled in Half-Life level editing when I was a teenager (sometime around 2000/2001), and never went back to it, but I decided to try my hand at making something worthwhile to release, around five years ago - perhaps spurred on by a lack of Episode 3. A lot has happened in this time - and releasing this marks the end of a long journey for me. The reception I have received has definitely made it all worth while.

I have just released v1.2 - which I hope should fix the last few crashes. A couple of minor bugs may remain, but I no longer have any real time to spend on this aside from fixing issues that prevent it from working - but please do not hesitate to send any issues to me.

On a personal note - I have something to ask. A few months ago, I became a father to the most wonderful little boy in the world. However, when he was born, we found out moments later he had an un-diagnosed heart condition which meant he would not live without immediate open heart surgery. For my wife and I, this was the hardest and most difficult time of our lives, but thanks to the incredible team at the Royal Hospital for Children in Glasgow - he has made a full recovery after surgery and is expected to lead a normal healthy life. There is nothing that can prepare you for this kind of situation, and not everyone is as fortunate as we were.

I would like to ask - if you enjoyed my work and have the means or the inclination - please make a donation to the Glasgow Children's Hospital Charity to support these wonderful people who saved my son's life. Donations will help save, help and enrich the lives of other children.

Thank you, James
