What are all of the possible endings?

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?

Update

According to http://en.wikipedia.org/wiki/Indiana_Jones_and_the_Fate_of_Atlantis:

Three bad endings see one of the protagonists undergo the second transformation if Indiana could not convince Ubermann to use the machine instead, or if Sophia was not freed from her prison or Nur-Ab-Sal's influence. In the good ending, Atlantis succumbs to the eruption of the still active volcano as the duo flees from the city. The final scene depicts Indiana kissing Sophia on top of the escape submarine, to comfort himself for the lack of evidence for their discovery.

This doesn't really tally up with my experience/interpretation.
