Console and Cheat
Enable Console Browse to your C:\Documents and Settings\<username>Application Data\Gearbox Software\Earned In Blood\<profilename> folder

You may need to enable "view hidden files/folders" under tools in Explorer.

Open EiB.ini in notepad (allways backup EiB.ini first)

Search for Consolekey=0

change to Consolekey=147    (some sites say 192 didn't work for us)

search for bEnableDebugConsoleAndMenu=False

change to bEnableDebugConsoleAndMenu=True

save EiB.ini and exit

load game using that profile

now you will have a console if you press the @ key (UK keyboard) (US keyboard could be " key ?)   
(some sites say the tilde key ~ didn't work for us)

Now enter cheats  codes below in console when in the game.
