Killzone Shadow Fall is a 2013 first-person shooter video game developed by Guerrilla Games and published by Sony Computer Entertainment for the PlayStation 4. It is the sixth game of the Killzone series and the fourth game of the series for home consoles. Killzone Shadow Fall was released on 15 November 2013 as a launch title for the PlayStation 4 in North America and 29 November 2013 in Europe. Taking place 30 years after the events of Killzone 3, Shadow Fall follows a new set of characters, putting players in the role of Lucas Kellan, a "Shadow Marshal", who is investigating a rising threat in the continuing war between Vekta and the Helghast.

As the first game in the series made for Sony's next-gen console, Killzone Shadow Fall received a number of changes to the series formula. The single-player campaign is more open-ended and stealth-based than its predecessors, and the multiplayer modes feature new customization options for weapons. The game also introduced a new proprietary in-house game engine called Decima.

The game received mixed reception overall; it received praise for its visuals and multiplayer modes, while criticism was directed towards the game's single-player mode and several gameplay features, although several critics appreciated the game's attempt to change direction from its predecessors, as well as its more open-ended level design. Critics also criticized the title's lack of innovation as one of the first eighth generation games. As of January 2014, the game has sold over 2.1 million copies, making it the first PlayStation 4 game to surpass the million copy mark and one of the best-selling PlayStation 4 games.
