Games : What are all of the possible endings in Indiana Jones and the Fate of Atlantis?

So far I have managed to pull off the following endings:

1. Trick the scientist into experimenting on himself - where you escape with Sofia


2. Trick the scientist into experimenting on himself but have Sofia intervene - you escape alone


3. Turn yourself into a god - obviously a bad ending

From what I can tell, having Sofia in the room with you or not gives the same outcome for the third ending listed above.

Are these the only endings?

Have I missed any?
