Extracting files for GTK to function
Extract the textures supplied with the game by opening the textures0.pk3 using winzip. The pk3 file can be found in the C:\Program Files soldier of Fortune II - Double Helix-GOLD base folder. Be sure that when you unzip it, You use folder names and that WinZip is in classic mode. Choosing Actions > Extract. Enter the path to your base directory, My path would be C:\Program files soldier or fortune double helix\base. Now go ahead and check the box to use folder names. Click the extract button. Extract the shaders that are used by the textures the same as you did the textures above. The shaders are located in the therest.pk3. This will create a large number of folders in your base folder which is normal. Also you should extract the models located in the models.pk3 again the same way as you did above. You are now all set to start making some MP maps for sof2 once you have watched the tutorial videos.
