When you report a bug in the comments section, please say what version you are using!!!

IMPORTANT!!!: If the manhole cover does not show up to you (Which it really should...) open the console with ` and type Coc N9Comm. This will teleport you inside as if you had activated the cover. Can someone who has this issue do this, then head back outside, and tell me if the manhole is there?

The Story

You stumble upon an old military bunker in the Mojave Wasteland. Inside the entrance, a mid-aged man resides. He mysteriously knows how to get inside, and invites you to take a look, being too scared to do it himself. You enter the bunker, and are pulled into a deep story that spans over 200 years! You are accidently sent back in time, and you must aid First Lieutenant Pierce Mitchell, while he fights to free his colleague from captivity, and save what is possibly America's only chance at winning the war. The Deimos.

How to start it.

At the Nipton Road Rest-Stop, South of Primm. There is a manhole in the middle of the parking lot. Enter that, and enjoy the mod.

IMPORTANT!!!: The laser barrier WILL kill followers that enter it. Please tell them to wait before doing so! I had to make a tough decision, but this is a no-follower quest mod. It allowed me FAR more freedom when it came to scripted cutscenes and story. There is no easy way to account for non-vanilla followers.

Note: If when you download the mod, you get a 'unexpected end of archive' type error and cannot open the rar, and it is less than 27mb, you can do one of two things: Either download from another server, or wait for the server to synchronize with an uncorrupt file. (Every hour or so) This is simply something that sometimes happens with the way the nexus servers work.


None! This mod only requires Fallout: New Vegas! No DLC, no NVSE, no AII. Just the base game.


- 1.5 to 3 hours of gameplay.
- Adds a brand new story to the Mojave Wasteland.
- Fully voice acted!
- 10 new interiors cells, and one exterior worldspace.
- 1 new weapon. (Altered off the Tesla Cannon)
- 1 new armor. (Altered off the Radiation Suit)

Please report any bugs you find! I did my best to make this bug free! I will be very agressively patching the mod for about a week, so report any bugs or incompatabilities!

Before saying you have a problem, please ensure that you have the latest version of the mod and use a clean save! I have had some bug reports solved because the person simply needed to update.


Extract all the files into the Fallout New Vegas/Data folder.

Thank you to the boys and girls over at the Bethesda Softworks Forums for all your support! I wouldn't have been able to do it without you.

If you liked this mod, have Fallout 3, and want to try playing my other mod, check it out at http://fallout3nexus.com/downloads/file.php?id=15513. It's my first mod ever, but overall people have loved it. It is much longer, and adds 3-6 hours of gameplay.
