Yes! They’ll work with any VTT site or software that allows the upload of .JPEGs. Each map is less than 5MB, which works great with a free Roll20 account (we personally love FoundryVTT and recommend buying it as one of the best applications). Sadly, we haven't yet added walls, lighting, sound, etc. to all our maps directly for those platforms. But, if you grab our Quarantine Bundle with over 520 maps, it's now FoundryVTT ready with walls, lighting, sounds, and some animations! If you'd like to have a look at how to install them, you can find our instructions here. Plus, if you want to try running one of the FoundryVTT ready maps, download and try a free module here!
