As with the codes I posted for Heroes of Might and Magic III, I don't take credit for these so I do not know if they work once you update your version.

First, start the game with the command line parameter of beatrix. You may do this by modifying your shortcut to the game. Your game directories may vary from the example. (ie: "C:\Age of Wonders\aow.exe" beatrix)

Then you may press [CTRL] + [SHIFT] + C (you should hear a PING noise)
