📋 About This Mod
MECHANIST OMEGA
An Antagonist Quest Mod
The Antagonist quests are a planned series of mods (this being the first). Each containing new enemies, weapons and armor, all packed into a new dungeon, each with a unique boss at the end to be defeated and looted.
What's in the mod?
A secret Institute facility, a whole lot of robots and a power armor set with more attachments than the mind can comfortably comprehend.
Where do I start?
Behind the concrete building at the Robotics Disposal Grounds is a hatch (pictures up above if you're stuck).
What should I expect?
Violence, excessive terminal based lore and bad voice acting.
What level should I be?
The enemies inside are levelled to the player, but I would still recommend at least level 5, as the boss is fairly tough.
Where is my Turretbot companion?
Well he should be either in the Mechanist's Vault, OR in the main entrance once you've been through the dungeon.
MASSIVE thanks to pinedog (https://www.nexusmods.com/fallout4/users/51672261) for retexturing the power armor to beautiful heights in version 1. 2.
Also credit to SavrenX for elements of their robot textures (https://www.nexusmods.com/fallout4/users/55611457)
Things to note:
- This mod requires the Automatron and Nuka World DLC.
- I have never done level design before. Please be gentle.
- After looting the Power armor from the boss, sometimes the attachments will 'float'. Take it to the PA workbench, scroll through the torso mods a few times, that should set it right.
- When scrolling through power armor mods, the attachments may 'stack'. This is a vanilla issue as far as I can tell. The 'stacked' mods will disappear as soon as you enter the armor.
- This mod makes much use of the Mechanist armor from the DLC. I would recommend this high quality texture mod for use with this one: https://www.nexusmods.com/fallout4/mods/13053
