I pulled all three levers and the door to go down to the next lvl is still locked. I didn't kill the 3 unarmed soldiers.
Killing the unarmed soldiers may annoy the Goddess a bit but it has nothing to do with going onward.
Isn't there another lever to pull (I'm going by old memory here)? Check the map of the level.
there are 3 levers and i have pulled them all plus if i kill them i freeze like something is going to happen but nothing does
So there are - mm memory is obviously failing.
Sounds like it could be a bug - if you don't get a better answer you might want to post it in the bugs section.
