Hello folks, so I defeated the Master and already escaped from the vault, but I'm stuck in the last door, when you come out of the basemant. I can't unlock it and I don't have the level to lockpick it, and I don't know what to do becouse of the timer.

Wait why would the door be locked in the first place?

Which door can't you open? The secret bookshelf door or one of the ones you need a Children of the Cathedral key to open?

Since you already opened the doors to get to the Master they shouldn't be locked now.

I just went through the bit with the master and I can't see a locked door...

Go backwards open door head in the same direction go to the elevator on the other side then go to floor 1 then down entrance out the vault door go down the cave and head left to the wall with the bookcase click on the wall and then go to the staircase and then to the main floor of the cathedral.

I don't see a lock

You can go through the bookshelf door when a child of the cathedral walks through it without the need to unlock it. If you leave the map quick enough the door should stay open for you walk back though when your on your way out.

Thanks for the information, but I was playing just now and it was suddenly open, but yesterday wasn't, even I tried all the things said. But my next problem is that I can′t play Fallout 2, it says ''Error initializing video mode 640x480 '' And I don't know what to do
