3. How do I add <insert WAD or SOC file here> into the game?
There are several ways to do this.

• Use the launcher in the files section and add them into the WAD Files section.
• Use the console and type "addfile filename.wad".
• Use a command prompt and type the parameter " -file filename.wad"

Generally, it’s easiest to use the launcher or the console, but use whatever method is the easiest for you.
