Demigod Specific
How do I unlock all of the Demigods? Some appear to be locked.
Go to the Demigod Start Menu icon, right-click on it, and select 'Run as Administrator'. Log into Multiplayer, and that should activate the new demigods. You should only need to do this once. If that does not work, you may need to host a Multiplayer game for it to register properly.
Can't log into Demigod Multiplayer?
Try deleting the 'Game.prefs' file which is located here: YOUR USERNAME\My Documents\My Games\Gas Powered Games\Demigod
(Deleting this file will remove any user settings you've made to the game)
Then launch the game as Administrator from it's executable file located here:
Steam: C:\Program Files (x86)\Steam\steamapps\common\demigod\bin
Demigod manual
Right click on the game in the Steam library and choose 'View player manual'.
Alternately, there is a PDF manual available in the "bin" folder of the Demigod directory. By default, it is located here:
C:\Program Files\Steam\steamapps\common\Demigod\bin\DemigodManual.pdf
C:\Program Files\Stardock Games\Demigod\bin\DemigodManual.pdf
