This must be entered in the host server for
LAN gaming before other players enter your map. 

Hit the chat screen while in the map 
(~ by default) and enter impulse (1-1000) then 
press + reload before letting other players into
your map. 

impulse 101 is for full credits
impulse 102 is for chickens instead of blood. 

To enter bind "g" or any other key to the cheat 
is useful as it saves time during gameplay.
