Killzone Shadow Fall

Sony revealed the first details on Guerilla Games' Killzone: Shadow Fall at the PlayStation 4 reveal, and now Guerilla Games producer Steven Ter Heide confirms on PlayStation Blog that the game will be a launch title. There's no release date yet, for either the console or the game, but we'll no doubt hear more info on that count in the months to come.
Killzone: Shadow Fall picks up 30 years after the events of Killzone 3, with the world split up between the Helghast and Vektan factions, living side by side in a future city that is cut in half by a giant wall. You play as the Shadow Marshal, "the most special of special forces," as you're tasked with keeping the peace.
Based on Sony's brief look at the game during PlayStation Meeting 2013, you're not very good at your job. But hey! Shooting things!
