Wondering what the creator of Thomas Was Alone has been doing? He's been making Volume.
It's a stealth-oriented, narrative centric stealth puzzler, where the player inserts themselves into the Volume "to halt the corruption of Gisborne Industries". Mike Bithell, the game's creator, describes it as a "reimagining of the Robin Hood legend".
It's available for US$18 on Steam. It's got some interesting talent in there, with Andy Serkis (the voice of Gollum) paired alongside YouTube star Charlie McDonnell, while the Thomas Was Alone narrator Danny Wallace has a role as well.
Volume's launching on the PS4 and PS Vita (although the Vita version will be delayed by a few weeks), but there's no listing on the Australian PS Store at the time of writing. Chances are it'll probably be around $20-25, but when a listing goes up (or the developer confirms with me) I'll update this post and let you all know.
