A neat cheat has been discovered that will allow you to play as the NOD faction in the recently released Command & Conquer 3: Tiberium Wars demo.
While the standard set up won't let you change the army you play as in a skirmish match, by following the directions below you'll be able to take charge of Kane's fanatical army and put the boot in to the goody-two-shoes GDI for a change. Just point your eyes down for the vital info.
Select Skirmish mode from the main menu, then hover over the army column.
Open the drop-down-box, which displays the army options - then hover your cursor over 'NOD'.
Press 'n' on your keyboard and simultaneously click the left mouse button.
Then, go to the computer's army selection box, and repeat the trick - only hovering over 'GDI' and pressing 'g' on your keyboard instead.
It may take a few tries, but it definitely works - and it's certainly worth it! Credit goes to the clever chaps on the Evil Avatar forum for uncovering such an excellent exploit.
