Hey can anyone clarify this one for me. I cleared the secret chamber and in the end there is this room with three "doors". In the map you can see that behind the one is the exit, but ALL of them are locked and it seems like there is nothing to be done.

 

Is there something I'm missing or is it a bug? I tried to find something about it and all I could find was something like: 'yea just take the door with the exit' ..

 

Thanks in advance.. I hate to be stuck

What planet?
