Hey guys. So I'm trying to find my way back to the vault exit so I can initiate the sewer side missions, but I can't find the spot and there is no [censored] map in this game that I can find. Can anyone help me out? I'm trying to work my way back from the Hagar settlement.

Starting from the front gate take a right and head straight. Soon you'll see a tent set up and few items. Right next to that is a sewer. There will be a man there depending on how far you are in the game. Anyway not to far from that on the left you'll see the wasted garage, right past that there will be a very sharp left turn. Go down there and you'll see the garage, vault and sewer.

Basically take at right directly coming out of the Hagar main entrance. You can't miss it. You went too far if you come to a dead end where ghost hide out is.
Hope it helps.
