After being a commercial and critical success in digital stores, Ziggurat is heading now for Retail!
Specific dates may vary depending on platform/country, but it should be available on most european countries by next week, for all platforms (Steam/PS4/Xbox One). United States will have to wait a bit longer.
By the way, we’re aware of an issue with the PS4 retail version, related with achievements (wrong achievements being unlocked). We’ll issue a patch as soon as possible to fix this issue. This issue is not present in the digital version.
