This mod fixes the Sandbox in Vault 88 so that it covers the entire Interior cells build areas, this includes the Pharmacy. Nav mesh has also been fixed and even added in spots it was missing in. The Pharmacy was fixed allowing the upstairs and new sub basement to be used also, Power an water source was added for easier building. The Water tunnels have been redone and made usable with a new huge building area located at the end of the other tunnel. In the Security room where you first come in at there are Respawning chests with armor for your Vault 88 settlers, these are set up just like the Vault suit one is. The new Vault 88 security armor has new custom #88 Textures to match them better with your new Vault, Helm is also provided in the chests along with the Lab coat and the Police Sunglasses. The exit load doors have been changed except the Pharmacy and Main door by the Quarry. The new load doors lead to safer places such as Jamaica Plains, The Atom Cats Garage, in the Roxbury Station building where there is cover from the Mutants, and the Glowing Sea outpost by the overpass (utility exit from old subway lines).There is also a new load door on top of the Pharmacy for Sniping and Sneaking purposes. The build bar was also increased to compensate for the new build areas added. You still have to enter and complete the quests for vault 88 like you normally would have to, and it is highly suggested you do so before building in the new areas.
