basically its like the way qounqer works.....ive just used the same way but put the multiclient patch.......
Find the CO2 application (should be in your CO directory), it will be called Conquer.exe or just Conquer with application underneath it.
1. Create a shortcut to this application and put it wherever you want, on the desktop is best.
2. Right click the shortcut and select Properties
3. In the window that opens click the Shortcut tab at the top and locate this text "C:\Program Files\Conquer2.0\Conquer.exe"
4. Add the word blacknull to the end of this text like this "C:\Program Files\Conquer2.0\Conquer.exe" blacknull
Note that the quotation marks ARE REAL and there is a space between the last quotation mark and the blacknull (from qonquer site)
when u have created the shorcut then........
patch conquer till the newest patch.........
then get the multiclient Hacks (or tennie not sure) has made paste it into CO directory ()
then double click the shorcut on desktop (the one you made of the client application)
it should work works for me
this is the way i use the multi client if it helps some people
