Alrighty, lets get some ideas for VC2 demo cheats on the go shall we. Now i cant play this remember so give me feedback if it works.
Anyway, extract vc2onlindemo.cbf and go to ini\players\mp and open whichever class you select.
In the ini file go to the line that sais
SpeedStand = 6.0 , 3.5 , 2.8 , 3.5
and edit 6.0 to say 20.0 and repack (tutorial on repacking in the retail section). You should now be able to run faster than any other player in the server when standing!
