Sierra's Half-Life Site Counter-Strike - Opposing Force - Patches - Steam - Bots - Addons

Here are the official add-ons and patches for Half-Life, and a couple of bots. Note that you don't have to download patch files manually - you can use the Sierra Utilities shortcut installed with Half-Life to automatically update the game to the latest version.

To find out which version of Half-Life is installed, either check the console within the game, or the Version tab of the hl.exe file Properties. For reference, the original retail version was 1.0.0.5, and the 'Game of The Year' special edition was 1.0.1.1.

There's also a patch available for running Half-Life on PCX2-based cards - if that's your bag, check out the PowerVR page.

Steam

Steam is a broadband distributed file system which Valve will be using to distribute it's games. Game updates are automatic, and it also includes an instant-messaging client (which also works in-game) and a server browser. Whether Steam is going to take off isn't clear right now, but the idea looks promising...

Opposing Force Patches

File Date Description Info Size
of1108.exe 11.03.02 Patch to update the English Language version of Opposing Force to 1.1.0.8. This includes multiplayer fixes and a couple of extra maps. Note that the Opposing Force 1.1.0.9 update included in the Half-Life 1.1.1.0 update doesn't include the maps; consequently, you might be best advised to update Opposing Force to 1.1.0.8 before applying the Half-Life 1.1.1.0 update. If you've already applied Half-Life 1.1.1.0 but you don't have the new maps (look for op4cp_park.bsp in the gearbox/maps folder), you can apply the 1.1.0.8 Opposing Force update, then apply the OpForUp.exe update that came with the Half-Life 1.1.1.0 update (you'll find it in your Half-Life folder).
If Sierra release a seperate Opposing Force 1.1.0.9 patch, I'll post it here.
