# Nuclear Option

Thank you to KopterBuzz for creating a Tacview exporter for Nuclear Option!

The instructions below apply to Tacview 1.9.5 and above, and are adapted from the instructions on \[KopterBuzz's GitHub] (<https://github.com/KopterBuzz/NOBlackBox/blob/main/INSTALL.md>)

### Installation Instructions

Download the latest release of the mod, [NOBlackBox](https://github.com/KopterBuzz/NOBlackBox/releases) and unzip it anywhere.

Download and install the latest release of [BepInEx 5](https://github.com/BepInEx/BepInEx/releases/latest) for Nuclear Option. You need the latest `BepInEx_win_x64` release of `BepInEx 5`.

Extract the contents of the `BepInEx` archive into the game root directory. It may look something like: `C:\Program Files (x86)\Steam\steamapps\common\Nuclear Option\BepInEx\`

Run the game once so `BepInEx` can generate its default directory and file structure.

Exit the game and edit the following setting in `C:\Program Files (x86)\Steam\steamapps\common\Nuclear Option\BepInEx\config\BepInEx.cfg`:

```
[Chainloader]
HideManagerGameObject = true
```

Copy the `NOBlackBox` folder into the game's `BepInEx` plugins folder. It may look something like:

`C:\Program Files (x86)\Steam\steamapps\common\Nuclear Option\BepInEx\plugins\NOBlackBox\`

In Tacview, ensure that the Advanced Options add-on is activated in the Add-ons menu, and make sure Auto Terrain Switch is enabled. This will ensure the proper map is displayed depending on the mission.

Now each flight will be automatically recorded in `%USERPROFILE%\AppData\LocalLow\Shockfront\NuclearOption\Replays\`
