📋 About This Mod
The Master's Army returns to dominate humanity. Can you bring an end to their reign of terror, or will you die at the hands of the Super Mutants?
This is a new world and set of quests allowing you to travel to Mariposa military base, the source of the Master's super mutant army (from Fallout 1). There are a couple optional quests to either join the Unity or Lost Hills Brotherhood chapter (Added in 3. 0)
This is NOT a fallout 1 remake mod. It is based off fallout 1 and there is a lot of consistency, but I took liberties to make everything 'better' for new vegas. This is a fairly balanced mod, but it is challenging for even 30+ level players. You can get to the base by traveling to a passage to the north east (Map marker is automatically revealed like other dlcs)
Look out for easter eggs!

Q: Is this mod compatible with X mod?
A: I have no idea
Q: Can you make this mod compatible with X/Y/Z mod(s)?
A: I could, but I won't out of principle. (Making this mod compatible with a variety of modded worldspaces is beyond what I hoped to achieve with this mod. I'm sorry if this is disappointing but please respect my boundaries as a developer)
Q: Any plans to make this mod a full on remake of fo1/add more fo1 features?
A: as of 25/04/29 I'm working on a fallout 1 remake made in fo4 ck. My plan is to have all locations and major quests/npcs available in this mod. I've made good progress so far. Not 100% when it will be done but maybe by 2026 sometime...
I chose not to do it in fnv or fo3 bc I wanted to take advantage of the nice features of fo4 engine.
I chose to do it solo bc I didnt want anyone slowing me down or creating conflict with my ideals for this mod (getting something out there is my top priority, not immersion, completeness, or fancy voice acting/animations/3d objects etc...)
