# Marvin - Chest screen

## Preparation <a href="#preparation" id="preparation"></a>

In this guide you will have to edit vmt files. I would recommend you to use the software [VTFEdit](https://noskill.gitbook.io/titanfall2/how-to-start-modding/modding-tools) to edit them. You can use text editor for that such as Atom, NotePad++, VIM and many other ones would work fine.

Locate your game folder and find this folder if you are on Origin:

> Origin Games\Titanfall2\vpk\\

Or this folder if you are on Steam:

> Steam\steamapps\common\Titanfall2\vpk\\

Copy these files and paste them in a backup folder somewhere else:

* `englishclient_mp_common.bsp.pak000_dir.vpk`
* `client_mp_common.bsp.pak000_000.vpk`

You will need the Titanfall VPK Tool, the program which will allow you to open and repack Titanfall VPK files. [Here](https://noskill.gitbook.io/titanfall2/how-to-start-modding/modding-tools)​

## Unpacking <a href="#unpacking" id="unpacking"></a>

Now that these files have been backed up and everything installed. Navigate to your game folder and open this file:

> Origin Games\Titanfall2\vpk\englishclient\_mp\_common.bsp.pak000\_dir.vpk

After following step by step the previous link

Rename `pak000_000.vpk` *to* `client_mp_common.bsp.pak000_000.vpk`

Rename `pak000_dir.vpk` *to* `englishclient_mp_common.bsp.pak000_dir.vpk`

Place both of the renamed files back into your game directory and then launch Titanfall 2. You should be able to see your changes!
