CMON has launched their Kickstarter campaign to add new digital assets like soundtracks and art books for some of their previous games. They're HATE, Zombicide: Green Horde, and Rising Sun. You can also pledge for those games as well. Well, you could've if they hadn't all sold out super-quickly, anyway. But you can still possibly sign up for the pledge manager and get some stuff there.
From the campaign:
The CMON Time Machine campaign is structured a bit differently than other campaigns. We're taking you to revisit past Kickstarters, Rising Sun, Zombicide: Green Horde, and HATE looking to fund brand new Soundtracks for them, as well as Digital Artbooks: The Kickstarter Exclusives from Rising Sun and HATE, and a brand new one for Zombicide: Green Horde and Black Plague.
With this also comes a new chance to pledge for those campaigns, acquiring these games along with many of their exclusives, as well access to a Time Vault (in the Pledge Manager) where many other leftover Exclusives from past campaigns (Arcadia Quest, The World of SMOG: Rise of Moloch, Zombicide: Black Plague, and Blood Rage, to name just a few) will be available.
The campaign funded almost immediately, but as it's a super-short campaign, there's only 3 days left.
