To access the cheats in Krossfire, you must do two things:

     1.The  game  must be run with the command line option '-badnews'.

     To do this you should make a shortcut to the kknd2.exe file. Next
you  need  to  edit the properties of the shortcut ([ALT]+[ENTER]). In
the  target  field,  add  '-badnews' to the end of the line. It should
look something like this:

C:\Games\KKND Krossfire\Kknd2.exe -badnews

     2.To  activate  the cheats in the game, you must press [CTRL] and
[TAB]  together  at  exactly  the  same time. It may take you a little
while  to  hit them together. When you do, a message will be displayed
saying 'Cheats Enabled'.

These are the cheats:

[CTRL]+M                2Extra money.
[CTRL]+C                Win level.
[CTRL]+F                Lose level.
[CTRL]+W                Turn on waypoint information.
[CTRL]+E                Turn off waypoint information.
[CTRL]+T                Turn off the fog of war - 
                        this may activate enemy units on the map.

     To  use  a  custom  unit  configuration file in the single player
missions,  run  the  game  with  the  command  line parameter '-stats'
followed by the name of the configuration file. For example:

C:\Games\KKND Krossfire\Kknd2.exe -badnews -stats justybear
