i used the faq but i am just too stupid to do it right. help? it's the halo mod if that helps

Make a seperate folder called "Soldat 2" or "Soldat Backup" and copy your entire current soldat folder to it.

Then

Run the winzip/winrar file (the one that you downloaded for the Halo mod). Unzip the files to your original "Soldat" folder. You should now be able to run the game with the mod. If it's the Halo 3.0 mod, there might be an installer of it's own, or perhaps a shortcut link automatically made.

which halo mod? i remember that halo 3.0 mod was packed in an .exe file
