God of War's hovedfokus har været historien i spillet, hvilket også betyder at spillet er meget nemt at lække. Derfor skal udvikleren også være påpasselig med hvad der vises frem før udgivelsen, da det potentielt kan vise for meget af historien.
Ifølge spillets director Cory Barlog har det været direkte ulideligt at skulle være så hemmelighedsfuld omkring spillets udvikling samt historie, og det er også tydeligt at høre at det har taget hårdt på ham:
"Yeah, that nearly killed me. There is a lot of stress in trying to get people on board with concepts and ideas, and pitching and convincing and trying to keep everyone on target, and that's really hard, right? But then in the end, for the last year and a half, I had to ensure that everyone across the world aligned with what we were doing, and didn't let any information out on an incident in the game. Wow. I have never experienced that much stress. It is a wonder that nothing got out- actually, I think it did get out, some information leaked, but fortunately it didn't permeate too far out into the ether for everyone to catch on to it.
We were able to keep on top of it. But it was very stressful, trying to ensure that everyone could get the same experience, and it required a lot of great collaboration between the marketing and PR groups to be flexible, when I would have a fit of some sort, and realize "Oh my god, we have to get this out now, we have to do this, our plan was to do this, but let's just go!" Or something might be getting leaked, and just getting on top of that as quickly as possible, even though the information was there, it went away fast enough that nobody caught it."
