Call of Duty: Ghosts AI development slowed by lack of final PS4, Xbox One hardware

Development of AI for Call of Duty: Ghosts is taking longer than the game's graphics because Infinity Ward has yet to receive finalized versions of the PlayStation 4 and Xbox One hardware, executive producer Mark Rubin told Official PlayStation Magazine.

Rubin said work on AI is "slower than some of the graphics" because the studio lacks the final hardware, noting the delay has caused Infinity Ward to be more cautious with the scope of the game at this point in time.

"Obviously we are in crazy early development and we will have to see how the consoles play out," Rubin said.

According to Rubin, AI enemies in Ghosts will react differently to certain events in the environment, as well as other dynamic instances such as Riley attacking.

"They might behave differently to the dog, or behave a little differently compared to the events that are happening in the level," Rubin said. "They take some of the environment cues and pay attention to them. A lot of times they just kind of ignore the environment, they are just like, ‘OK this guy is supposed to be here I'm shooting, but the building is falling all over me... No, I'm still shooting you.' So sort of doing stuff like that. It is subtle, really subtle. AI in general is one of those things [where] the subtle things are often easy to notice when it is bad."

Rubin added Infinity Ward is making "big strides" in development but can't push things further with Ghosts' AI until they know exactly what they are working with for the PS4 and Xbox One.

"We need some hardware, some finished hardware, before we can really expand," he said.

Call of Duty: Ghosts will launch on Nov. 5 for PlayStation 3, Xbox 360, Windows PC and Wii U. The game will be a launch title for the Xbox One and PlayStation 4.
