How to install mods for Fallout 3 and New Vegas (NMM)


With my guide, you will be able to mod Fallout 3 and New Vegas (Including Skyrim and Oblivion.) This will be quick, so don’t worry about losing precious time. Post in the comments the things I missed!!!! I lied, this might take some time.

Step #1: Download Mod Manager

To start this off, you will need to go to this website: Nexus NV[www.nexusmods.com] or Nexus F3[www.nexusmods.com]. You are then going to click on the top right corner, you will see a link named MOD MANAGER, download it and start it up. It will need to scan some games it uses, so click on the green check mark to verify that game is on your computer, click the red “X” to pretty much say, “That’s not on mah computer!!!” The Mod Manager is up and loaded.

Step #2: Mod Spree!!!

Since you have the manager downloaded, you can go to the normal site for New Vegas Nexus[www.nexusmods.com] or F3 Nexus[www.nexusmods.com]
You can either search or go to files and find some pretty cool mods. WARNING!: You need to sign up to download big mods (Example: The Rockwell Pursuit, New Vegas) there’s the basic account type (Free User) and then there’s Premium Membership, which you have to cost money for and re-new (like Playstation Plus and XBOX LIVE.) Since you found your mod, you can download it. If you want to download it through NMM, then click on: DOWNLOAD (Manager) If you want to do a manual install, click on: DOWNLOAD (Manual).

NOTE: Some mods require New Vegas Script Extender (NVSE). Please make sure you read the description of mods, as you might have to download other things.

Final Step: Activate mods

Open the Nexus Mod Manager and click on the game you are modding. After it is done loading up, go over to the tab named Mods and click on it. You will be brought to the list (which is empty) and you click on the square with the green arrow and drop down menu button (Top Square.) The file explorer will come up, go to downloads and find your file(s), after you click OPEN, it will be put on the list. Double click on the file (if it doesn’t have a green check mark by it) and it will enable it. Certain mods WILL require the program(for New Vegas) NVSE, which stands for New Vegas Script Extender. In the description of the mod, it will say the requirements for that mod. After the mod is activated, test it out by playing the game (if being played while you do this guide, than restart the game.) If your mod works, than congradulations, you can easly mod certain Bethesda games and others!!!

As a user has pointed out in the comments, NMM isn’t always supported by mods. Big mods, like Tale of Two Wastelands, simply won’t install. Any mod around 2 GB just won’t work and will cause many issues, such as NMM crashing or it will ruin files. Please be careful and research in the description of mods if NMM is supported as an installation alternative to manual! Even though NMM came out a few years ago, it is still in beta, so don’t expect it to do everything like it’s God’s gift to the modding community.
