What's in the mod?
- Upon loading the quest will start. Read the strange letter in your inventory to embark on a (brief) journey to unlock the new robot options and collect a new armour set.
New options include:
- 2 x new robot workbench options ('Occult' and 'Corrupted') - Available under 'SPECIAL' in settlement builder after completing the quest.
- New 'Corrupted' Protectron options (which will be familiar to those of you who played Vault 117!)
- New 'Fungal' Assaultron options.
- New 'Homunculus' Sentry Bot Torso.
- New 'Geist' Mr Handy Torso.
F. A. Q
- Requirements - Automatron, Far Harbor and Nuka World DLC
- Mal-eh-f....what? - Mechanism Maleficarum (pronounced "mah-leh-fi-KAH-rum") - Literally meaning "Device of Evil Intentions".
- My robot workbench doesn't have candles and flames and stuff - That's because I decorated mine using vanilla settlement objects, plus some items from this mod: https://www.nexusmods.com/fallout4/mods/10075
