Call of Duty Ghosts: not a new engine, but is upgraded says dev

Call of Duty: Ghosts was shown at Microsoft's Xbox One reveal on Tuesday, and with it, speculation of a new game engine followed. It's not an entirely new engine, Infinity Ward's animation lead Zach Volker has confirmed, but it has seen significant upgrades.

If you haven't seen the game running yet, you can check out our trailer coverage here first.

Speaking with OPM, Volker said of the Ghosts engine, "When we’re talking about a new engine we’re talking about upgrading significant systems within in that engine. We’re not talking about throwing it all away and saying we’re starting from the ground up".

Volker added that it would be “impossible to develop a new engine from the ground up in a two year cycle," and added, “What we do is we say, ‘okay what are the things that are significant and that we would say that are encompassing of the engine or its visual quality? Are those being upgraded in a significant way? Alright, then I think that warrants that we’ve got a new engine on our hands”.

So it's not new-new but new-enhanced. Do you see?

What do you make of the above? Did the Ghosts footage on Xbox One look good regardless of a totally new engine? Let us know below.
