Modders are kind of the best. Case in point: this amazing New Vegas mod which adds another joinable faction in the game. And not just any faction, mind you — it's the Enclave.
The mod — called "For The Enclave" — was made by Otellino and CNC. It took three years to make, and you can tell just by looking at what it offers:
This mod is designed to add the Enclave as a joinable faction within Fallout: New Vegas, complete with unique, fully voice-acted characters, various side quests and a storyline.
After the numerous defeats across all remaining fronts, the Enclave has splintered into their own factions with their own ideologies. Two factions are about to go head to head in the Mojave Wasteland, and General Jamison is turning to the Courier for help. Will he join the Enclave, or leave them to their fate?
For The Enclave consists of:
A joinable Enclave. (Henderson Bunker Enclave forces)
A fully fleshed-out 5 part series main quest - The third resulting in a large scale assault and the fifth a dramatic and explosive conclusion to the story.
A potential companion when enough progress is made in the mod.
Four side quests.
Full-fledged random encounters, with various possibilities depending on choices made during quests and progress throughout the main mission.
Re-implemented & fully functioning Chinese Stealth Armour.*
Various new interiors, exteriors and a brand new world space.
An Enclave Radio Station, courtesy of GCRust.
Fully lip-synced and voice-acted characters with all-new dialogue.
*The Chinese Stealth Armour in it's entirety was in the New Vegas game files and was NOT ported from Fallout 3.
Sounds amazing, right? After all, one of the best aspects of New Vegas is all the different factions you can interact with/join.
If you'd like, you can download the mod here. Here are the requirements necessary to play it, if you're curious:
You must have the latest version of Fallout: New Vegas on Steam. Illegitimate versions of Fallout: New Vegas will not be supported under any circumstances.
In order to join the Enclave, the player must be at least level 15 and have interacted with Benny from Fallout: New Vegas' main questline.
You will then be approached during your travels, assuming you do not use Fast Travel. If you do use fast travel, head to one of the three locations indicated in the Spoilers section at the end of the page.
And here are a few screenshots, showcasing what this looks like in action:
I might just have to return to New Vegas soon...
