Fallout Immersion Project - RobCo
"Automation for a brighter tomorrow - even if there's no one left to see it."
[Open Beta] This mod is under active development - updates and patches may drop anytime.
Your feedback directly shapes development!
Features
- Adds a large Fallout robot roster to Biotech mechanitor gameplay, including Eyebots, Protectrons, Mister Handy variants, Robobrains, Assaultrons, Sentry Bots, Securitrons, Liberty Prime, and more.
- Rethemes core Mechanitor progression by patching mech buildings, implants, apparel, weight classes, and subcore-related content into RobCo and General Atomics flavor.
- Expands robot progression with custom gestator recipes, dedicated boss groups, signal items, and research-gated encounters tied to Fallout-style scrap recovery.
- Works as an additive robotics overhaul on top of Biotech; pair it with Donaustahl if you want a cleaner removal of more vanilla immersion breakers.
Requirements
- Biotech DLC - Required (core mechanitor and mech systems)
Recommended
- FIP - Donaustahl - Optional (removes more vanilla leftovers for a cleaner Fallout conversion)
Development Notes
- This module is in open beta. Balance passes, naming cleanup, and compatibility refinements are still ongoing, so targeted feedback is useful.
- This mod is part of the Fallout Immersion Project (FIP) - a complete modular overhaul inspired by Fallout's lore. FIP is not affiliated with the Fallout Collaboration Project (FCP), but it is designed to complement FCP and other Fallout-friendly RimWorld mods.
