The post-apocalyptic setting of the game Fallout turns planet Earth into a radioactive wasteland, and therefore it is not surprising that the player repeatedly has to encounter bunkers and shelters, which can be very problematic to get into.
Instructions
Step 1
In the quest "The Velvet Curtain" you will need to get into the bunker from the Point Lookout add-on. You can get the quest at the Native House motel, in room 1D. You have to complete several instructions, which will be issued as intermediate missions (visiting the pier, opening a bank safe, searching for a spy, sinking a submarine) - upon completion you will return to the motel.
Step 2
Go to the restroom and search the toilet cistern - get cryptochromatic glasses. Travel to Calvert Manor and look for the greenhouse. Put on the glasses you found earlier, and you will see that several stripes are drawn on each vase in the greenhouse (in fact, these are Roman numerals). Find a terminal for entering a password in the room, according to the vases - this is 1323442.
Step 3
You can get to the shelter without going through additional tasks: it is enough to come to the estate and carefully examine all the cracks in the floor of the atrium. As soon as you go down to the underground location, the quest will automatically appear in your log as "completed".
Step 4
In order to go down to the Fort Constantine bunker, you first need to find this location. The marker will appear if some character tells you about the fort - otherwise you will have to look for a point on the map yourself. The hideout is located in the upper left corner of the map and looks like a regular gas station from the side. Go inside and go down to the basement - there you will see a metal door directly to the bunker.
Step 5
Find 5 holodisks scattered around the game world to get to the National Guard bunker. The first one is in a tent at the Anchorage Memorial location: be careful, a super mutant will be waiting for you inside. Number two you can pick up near the VAPL-58 Power Plant, behind a fence near one of the high-voltage line poles. The third is stored at the "Robercracker gas station". The fourth is located behind the Creepy Diner, and the fifth is in an abandoned church between the cemetery and the Germantown police station.
