This becomes immediately evident as soon as you begin the single-player campaign. This story has allowed Guerrilla to explore different, more subtle themes, in turn letting the team flex its artistic muscles in ways it never had a chance to. It takes place decades after the catastrophic events at the end of Killzone 3, with the conflict between the two sides turning into a bona fide cold war as a result of once again living on the same planet. “I think at some point the disc image that we were generating was around 180 gigs,” said van der Leeuw, revealing that “if we would have put all the levels in, which we didn’t, because then the disc image generator broke, it would have been around 290 gigs of data.Play Killzone has always been a bleak-looking game, a product of its equally bleak story surrounding two factions of warring humans, the Vektans and the Helghast, but Shadow Fall one makes a welcome turn for the colorful. If they had taken that approach with Shadow Fall, then the file size would have been colossal. This file size is after optimisation too – there’s been a lot of compression, as even Killzone 3 was bigger at 41.5GB on Blu-ray, due to duplicate textures and large video files in a multitude of languages. He also says that due to the more open nature of the game, the surface area is five to ten times bigger than that of Killzone 3.

The reason it’s around 40GB is because, well, it’s a next generation title, and that means next-gen textures: “The bulk of it is textures,” Michiel van der Leeuw told Eurogamer, continuing “”I think we’re probably a lot larger than the other cross-generation games, because we have no assets that have been made to a lower spec.”

Sony’s new PlayGo system will allow PS4 games to be played well before the hefty download has finished, with Killzone Shadow Fall ready to play after just 7.5GB of the 39.7GB download is complete – that’s less than 20% of the total file size.
