Hello! There will be one or two DLCs available on launch and they'll cost $4USD each, so between $8-12USD will be needed to get them all. But we're going to keep releasing more DLCs throughout the end of 2020 and into 2021. When we finally have the entire set of DLCs out, potentially by next summer, it'll be around $25USD to get every single one. Thank you very much for the interest :)
