-Can you replace a faction other than the Enclave?

No. As all other faction are either Vanilla/Official DLC, I won't be replacing them.

-Can you make a custom faction for me?

No. I have more than enough on my modding plate, and have neither the time nor desire to create a faction for you.

Check out FCOM 3. 0 Custom Faction Template , a template I made for creating your own faction.

🤖 AI-enhanced — based on mod data

FCOM 3.0 - UNSC Edition is a patch mod for Fallout 4 that replaces the Enclave faction with the UNSC from Halo, featuring ODST Battle Armor, Sierra 117 armor, Misriah Armory weapons, and new voice lines. It has 270 endorsements and was last updated in December 2019.

✨ Key Features

Replaces the Enclave faction with the UNSC
Uses ODST Battle Armor and Sierra 117 for armor
Uses Misriah Armory and MA37 & BR55 Service rifle for weapons
Adds new voice lines

📊 Pros & Cons

✅ Pros

  • Solid community support with 270 endorsements and over 12k downloads
  • Brings Halo flavor to Fallout 4, replacing a major faction for a fresh experience
  • Includes new voice lines, adding immersion beyond just visual changes

⚠️ Cons

  • Last updated in 2019, so it may not be compatible with the latest game patches or DLC
  • Requires external mods (ODST, Sierra 117, Misriah Armory) which adds setup complexity
  • Replacing the Enclave could break quests or storylines that depend on the original faction
🎯 Is This For You?
For Fallout 4 players who are Halo fans and want to fight the UNSC instead of the Enclave. If you're looking for a total conversion or gameplay overhaul, this isn't it—it's a faction reskin with new gear and voices. Skip if you prefer to keep the vanilla Enclave storyline intact.
📦 Install:Medium· 10-15 minutes

💡 Beginner Tips

  • Make sure you have all required mods installed and load FCOM after them in your load order.
  • Check the mod page for any compatibility patches if you use other Enclave overhaul mods.
  • Since this mod changes faction behavior, start a new game or use a save before meeting the Enclave to avoid conflicts.
