It includes the release of Resonance: The Adventures of Atlas & Deacon Volume One. A nearly four hour compilation of the last 100 videos.
There's also the option to download the compilation in four different episodes of around one hour each. This is probably how I'll be re-watching!
The vault also includes a short intro and outro by Atlas that won't be available anywhere else. You should be able to easily stream or download all the files. Please let me know if you have any issues. I will be adding this to my links page and sharing it on various platforms.
