Epic's Cliff Bleszinski announced at a Comic-Con panel today that Fortnite will be first title built with Unreal Engine 4 and will be a PC exclusive. Set for a 2013 release, Fortnite is a cooperative builder-shooter in which you'll build defenses while the sun shines and defend it at all costs when night falls.
"Next-gen's here. It's been here. It's a high-end PC," said Bleszinski, according to Joystiq .
The game's official site is live, and there's a batch of new screens below, as well as last year's trailer.
