I have a problem.

The main game worked fine and I've finished the campaign, but the expansion packs Spearhead and Breakthrough refuse to launch.

The startup text screen is filled with text like usual, but eventually it is halted:

As I try to launch Spearhead I get an error message on the startup text screen, "...WGL_3DFX_gamma_control not found"


and when I try to launch Breakthrough I get the same error message as mentioned above, but also the error message, "...GL_DOT3_RGBA_EXT not found"


Is there any way to correct this and get the game working?

You should state your system specifications and your OS. Also posting the whole log could help us helping you.

Generally I'd say it could be a driver issue, but it's strange considering that the original game runs fine.

It's Windows 8.1 with Nvidia geforce gtx (860M).

If you want to play any of the expansions you have to rename the Mohaa.exe file (which is in the installation folder) to Mohaa.exe.old then rename the executable of the expansion to Mohaa.exe
For example if you wanna play spearhead you have to rename moh_spearhead.exe to Mohaa.exe

It works! Thank you very much

You're welcome
