You know how there are floating spots on the sides where the gaps in the ledge are? There is a simple of an angel on the ground there? Well there are two more towards teh middle along the other walls' ledges. Look on the ground for angels and look at the roof for blue crystals. That is your key. One of them will just put up up on a ledge...one will put yuo right at a new door that opened up...but be careful out there!
Thank you for answering.
I've tried what you said but there isn't any way out. Where exactly should the door open ?
In the celing? I float up (I've tried all four crystals) but no way out (no door opened). HELP!
Yes, I did, before I've got the problems with a lot of bugs. For example after the jeep trekk i've lost all my weapons and medicins. I had to start all over again (once again). I really like the game so I can't stop playing it.
