This is a Steam Workshop mod for GM Forge (https://store.steampowered.com/app/842250/GM_Forge__Virtual_Tabletop/).

Alternatively, you can install it directly from this source, however it will not receive automatic updates so the Steam approach is the recommended option. You will need to extract this folder to the following location:
<YOUR_STEAM_LOCATION>\Steam\SteamApps\common\GM Forge - Virtual Tabletop\public\workshop.
I have decided to move on to a new challenge working on virtual tabletop related projects in my own independent space. I apologize to the GM Forge community who was looking forward to further work on Foundry Tactics, but I'm excited to tackle a new and more ambitious challenge with Foundry Virtual Tabletop (http://foundryvtt.com).
