📋 About This Mod
Description
This mod adds two quests to the game where you are encouraged to explore Vault 112 thoroughly. Don't expect keys and passwords to be where you remember they were. I know I wouldn't leave the key to the room where I lay dormant just laying there, in the armory. Makes no sense. Specially for someone as intelligent and paranoid as Dr. Braun. I've also tried to make exploration more rewarding. Vault 112 is not a big place but now if you visit the clinic, you can expect to find Aid kits and stuff that you would generally keep in a clinic. Don't expect old vanilla notes to say exactly what you remember they said. Don't take anything for granted...
Ever wondered how your Dad traveled the Wasteland with just a magnum? Doesn't make more sense to snipe your enemies from the distance if you travel alone? This mod also covers that.
There's also an explanation to why your father could manage to get into the Tranquility Lounger without wearing a Vault 112 suit. And I also fleshed out Dr. Braun's backstory with notes and enviromental storytelling. Now the FailSafe is not trial and error minigame. Instead, it makes sense and you can find hints of what the code is and why. And... to top it off you have the option to kill Braun...

Like many Fallout 3 players, I felt a bit dissapointed when I got into the Overseer's office and found... nothing. Nothing that mattered in any case. The whole Vault 112 and Tranquility Lane's quests felt a tad wasted and rushed so I decided to flesh out this part of the main quest a bit more. It feels like an important moment in the game. You finally find your father and you need to free him from a lunatic. Only it felt flat, un
