The game is described as a "story driven, episodic single player adventure." It's very different from the original Primal Carnage, which was a class-based shooter of humans vs. dinosaurs.
The game is currently expected for PlayStation 4 and PC.
Update: "We're going to shoot for being a launch title," said Ashton Anderson, founder and lead designer at Lukewarm Media mentioned at the event. "We're definitely going to be a launch title." He tells us the game will launch on PS4 first, with the PC version showing up two to three months later.
