Fortnite – PC exclusive uses Unreal Engine 4, releases in 2013

Today at San Diego Comic-Con, Epic Games revealed the first look at its co-op sandbox survival game, Fortnite, which will be exclusive to PC and the first game to utilize Unreal Engine 4.
During its Comic Con panel, Epic announced the game will release in 2013, allowing players to “explore, forage, collaborate and build by day in their own dynamic and expanding world.”
At night, they’ll have to work together to defend their fortress “from the forces of darkness.”
Attendees at the panel also received a first look at Fortnite’s building system, which is designed so that “players can use scavenged materials to quickly build and renovate structures of varying materials and complexity.”
