To surf through multiple scenarios in "The Fall of the Trident" campaign simultaneously, 
use the following trick. Pause game play, then press [Enter] to display the chat box. 
Enable the CHANNEL SURFING code. Highlight the text. Press [Ctrl] + C. Press [Enter] to 
enable the code, and then keep pressing [Enter] then [Ctrl] + V then [Enter] repeatedly 
to allow the game to initialize the loading of all the next scenarios in the campaign. 
Once you are finished duplicating, resume the game by pressing [Pause]. You should see 
the game loading the next scenario. Note: This will take awhile. The amount of time 
required to load depends on how many times you had duplicated.
