Before you can enter any of these cheats you need to enable the console commands option (you all probably know how to do this but just to make sure). In the main menu go to options then go into game options make sure "Developer Console" is set to yes.

When in game hit pause and then press (~) it is below the escape key (just to clairfy).

Ok now to the cheats, these are the ones that I use the most.

If you are using a custom map go to the mods section and click the mod you want to use (it has to be a map or custom map) then after clicking launch and it goes back to main menu open up the console (~) and type "devmap nazi_zombie_ (then the map name exactly how it is named) but I haven't found out how to do it with official UGX maps so sorry for that.

To enable the cheats you need to have a map launched and then you press the (~) key and type "sv_cheats 1"
