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.
There is also an optional 3.5 beta update hidden around the internet that is well worth the trouble finding it and the updated .fgd's for the games you want to map for..
Here's a link to a download on cstrike-planet.com. It requires Hammer 3.4 of course installed beforehand, as it is a patch.

It SHOULD work.
Why are you using a picture of Source Hammer?
this is a cool map creator
Doesn't install. The file is over a dozen years old. Good luck getting it running.
Huh. It works, which is cool, because I need it to work with Opposing Force, but... what the ****. What a downgrade from Source hammer. So many things that are way more complicated with GoldSrc hammer (like "what do you mean I can't scale the entity properties window?"-complicated). I'm glad it works, though.
Does this work with Half Life: Source? Reply as soon as possible please!
noooooooooooooooooooooo.
