Backdoors & Breaches is now available as an official Workshop Mod for Tabletop Simulator!

Backdoors & Breaches (B&B) contains 52+ unique cards to help you conduct incident response tabletop exercises and learn attack tactics, tools, and methods. This post is a guide for getting a virtual B&B game going.

Note: New attack, defense. and inject cards will be added periodically.

This is a multi-step process, but it’s not difficult. Our mod is built with Tabletop Simulator (TTS) and is hosted on the TTS Workshop. TTS runs on the Steam Platform.

Note: this guide is designed for Windows users, but you can do the same on Mac or Linux. TTS and the B&B mod work on any platform.

How to install Steam

If you don’t already have Steam installed, that’s okay. It’s super easy to get and free to install. Head over to: https://store.steampowered.com/

Now click “Install Steam” in the upper right-hand corner:

On the next screen, click “Install Steam”:

Save the ‘SteamSetup.exe’ file, then run the installer. Select your language, choose an install location, and at the end click ‘Finish” to run Steam:

At this point either sign in with a previously made account or click ‘CREATE A NEW ACCOUNT…’ to make a new account. Once your account is set up and you’re logged into Steam, then proceed to the next step.

How to install Tabletop Simulator

From the main ‘Steam’ menu, search using the ‘search the store’ search box in the upper left for ‘Tabletop Simulator’. It should be the first result and will look like this:

From the ‘GAMES’ menu, we will then select ‘Workshop’:
