Word on the street was that the developer that has been working on Bloodlines 2 is The Chinese Room, a British development studio (owned by Sumo Digital, who are in turn owned by Tencent). They have previously developed Little Orpheus, Everybody's Gone To The Rapture and Amnesia: A Machine for Pigs, although the latter two those were quite a while ago and a lot of talent has moved around since then.
Just a rumour of course. It struck me as plausible because firstly the Sumo group and their subsidiaries are widely used work for hire studios with the sort of technical skills to take a mid scale game to the finishing line, and secondly because it's not some kind of obvious fantasy pick.
At some point I should probably get around to requesting a refund on my Blood Moon Steam Preorder and do something productive with that money until they show the game again, lol.
