Until Dawn developer Supermassive Games has trademarked something called Shattered State in Europe.
Right now all we have is a logo to go on (via ResetEra), although the timing is certainly spot on as Gamescom kicks off this week. Could an official reveal be on the cards?
One interesting thing to note is that Shattered State is owned by Supermassive Games itself, unlike Until Dawn, which is owned by Sony Interactive Entertainment. This basically means the mysterious title could appear on other formats besides PlayStation 4.
That's about all there is to go on right now, although hopefully we won't have to wait long to find out more info.
In the meantime, why not give Until Dawn a go? If you grew up with the likes of Scream and I Know What You Did Last Summer, then you're in for a right treat.
