So far it’s just been announced that the first release will be Castlevania, which will be available at the San Diego Comic-Con in July. This likely means that a release for the general public will be available online shortly after (which is what they did with their The Last Of Us release).
But this is not today’s only announcement. iam8bit also announced that they will be releasing Petri Alanko’s Quantum Break soundtrack on vinyl. The release will be on 180g white with colored splatter vinyl and will feature new artwork by Christina Mrozik.
The release is limited to 3000 copies and is set for a Q3 2016 release.
