Cheats

 While in the detachment selection screen, hold down the control key and
 type

 Paladin.

 This enables you to use Knight Paladin units.

 During the battle, hold down the control key and type:

 EYEOFTERROR    - To be able to see all enemy units
 HERETIC        - Completes the mission
 CLEANSINGFIRE  - Your hit probability is increased to 100%
 WHITEDWARF     - Makes all your units invulnerable to ranged weapon
                  fire, not close combat

 P.S Control makes the selected unit fire so try to select a unit that
 has fired or it cannot fire.
