The Xbox 360 and PlayStation 3 versions will feature "most of the tech" offered by Call of Duty: Ghosts new, next-generation engine – but real-time lighting is still "beyond the capabilities of current-gen systems," Infinity Ward has claimed.
Discussing the differences between the current and next-gen versions of Call of Duty: Ghosts with IGN, executive producer Mark Rubin revealed that "most of the tech that we've put into the new engine will be available on current-gen.
"There's some obvious tech that isn't and can't be, like the Sub-D, the displacement mapping and the real-time lighting. That's stuff that is beyond the capabilities of curren-gen systems."
Rubin says that one of the big new features included in the current-gen version is Ghosts' new audio engine, initially created for Xbox One and PS4.
"We spent a lot of time trying to get some of the next-gen features that we were working on into current-gen," Rubin continued. "A good [example] for instance is audio. We created a brand new audio engine for next-gen. [It] has ADSR reverb in real-time so it's modelling your environment as you move through it; the locational battle chatter; the reactive emitters where, when I throw a grenade, basically the explosion causes other things in the world to move and shake and create noise. So you'll hear things rattling things behind you even if there was a grenade in front of you.
"All of that was built into a new engine that we made for next-gen systems, but once we had done it for next gen we went back and said we want to try and make this work for current-gen as well. We want to give current-gen players as much of the tech that we're putting in as we can, so I'm very happy that we actually - for the audio stuff especially – we were able to get that in the new engine for current-gen as well."
Call of Duty: Ghosts' multiplayer was revealed last night, along with confirmation that current-gen players will be able to transfer their online progress, unlocks and Season Pass downloads over to next-gen platforms.
The game launches on Xbox 360, PlayStation 3, PC and Wii U on November 5, 2013, with PS4 and Xbox One versions still to be dated.
