DARK FORCES LEVELS (GOB) New this month are DARK FORCES levels (also knows as GOB's). You have to follow a few simple steps to load these new levels. STEP 1: Copy the file to your Dark Forces directory on your hard drive. STEP 2: Once copied, go to your Dark Forces directory and type DARK followed by a dash (-), the letter U, and the name of the file. For example, if the filename is OPJUST.GOB, you would type: DARK -UOPJUST.GOB (note that the only space occurs between DARK and the dash). As with all add-on levels, updates, or patches make sure your original files are backed up. PC Gamer will not accept any responsibility for problems caused by these files.
