The mysterious new shooter from original Left 4 Dead developer Turtle Rock is powered by CryEngine 3, the studio has revealed.
"Yes, its all true. We are using CryEngine 3 for our next title, and yes, it's going to be awesome," read the message.
Very little is known about the THQ-published project, other than a planned 2013 release date.
"It's an incredible design," THQ core games boss Danny Bilson told Eurogamer earlier this year.
"I can't wait till we share the concepts of that game, because there is some gameplay in there I've never played before."
