📋 About This Mod
This is my very first mod, so please leave feedback, I would love to hear your thoughts. I wanted to try the CK out, and decided to share the result here.
If you like the level, comments and endorsements are very welcome!
DESCRIPTION
Hidden beneath the ruins of Concord lies a forgotten Vault-Tec regional office, long since abandoned after the bombs fell. Now the crumbling halls and collapsed cubicles have become home to a ruthless raider gang, turning the once-pristine corporate bunker into a stronghold of scavenged defences, makeshift camps, and bloodstained secrets. Explore a detailed interior of loot, enemies, and a new slice of wasteland history buried beneath the Commonwealth.
The entrance can be found just past the Red Rocket, heading towards Concord. Turn left on the road where the dead Brahmin is, and the Vault-Tec office is just on the left.
INSTALLATION
Download and install using your mod manager of choice, or manually download and extract into Fallout 4's Data folder [.. Steam\Steamapps\Common\Fallout4\Data]
REQUIREMENTS
Fallout 4 base game
COMPATIBILITY
It should be compatible with everything. I've tested, and I'm hoping the entrance doesn't interfere with any other mods based in Concord.
If you're using Fort Ivicic, then you may see some spare tyres outside the Vault-Tec office front door.
If you're using Beantown Interiors Project, please load it after this or you may have occlusion issues.
Some things might look out of place if you're using mods like Clean Water, Illuminated Billboards, or Regrowth Overhaul.
KNOWN ISSUES
No known issues at the moment.
