I got all of the symbols done correctly from above and have all 4 doors opened inside the sealed cave that once was and reached the end. How do I get inside the Lab? Where do I look to get in to it as I've looked all up and down the cave and can't seem to find an entrance anywhere at all. Thank you and have a great day!!!

Hi,
Welcome to the forums. If you turned all the rocks to the right symbols on top of the hill, all the doors should be in the right position. The lab is right at the end of the last part of the cave.You should be able to walk right into it. Hope that helps somewhat. The rocks that I am talking about are the ones you rotate up on the hill to select the symbols.

Hi,

I see two possibilities here.

1- it is possible to get lost in this underground tunnel. (walking back toward the entrance).

2- or, at least one of the door has not been rotated properly. (wrong symbol used)

It is possible to open them one at the time using each symbol and going back in the tunnel to check until it has opened. That is the way I did use, but it took me a long time to succeed.

Yes, all of the symbols are turned the correct way and all 4 doors are opened in the cave, but when I get to the end I reach a dead end which is the cave bluish wall that's part of the cave itself. Is this part of my game that may be defective or do you have a patch that may solve this problem that I'm encountering. Please ask other experts what to do so that I can finally get past this once and for all! I'm going nuts!!! Please let me know and have a great day!!!

From my end, it is the first time I see this bug and I am not absolutely certain how to go about it.

Three suggestions.

1- try closing the last door, go check if you see it closed. If so, try reopening it again.

2- If ever it does not solve your problem, I would check a good walkthrough to confirm that you have the right symbols.

3- If none of the above solve the problem, I would start a new thread in the Myst 5 technical forum and ask Heimdall G. if he could help you.

P.S.
At this time, it does look like that Heimdall G., gnorke and me are the only ones left trying to help people with Myst 5.
