Welcome to The Vault.
Down the years there’s been a number of items from both Last Minute Continue and Sonic Wrecks that have, for one reason or another been lost to the passage of time or have been voluntarily removed. For example, there’s a lot of original content from Radio Redux and the old Shadow Depository that is no longer available. It would be kind of nice if it was available again. The Vault is a place for that content to be viewable, playable, watchable and downloadable once again.
Currently The Vault is a work in progress. As for what that content will end up being you’ll just have to wait and see.
