Mensen schreeuwen al jaren door het feit dat de Call of Duty-games nog steeds op de engine van Modern Warfare draaien. Het mag wel eens vernieuwd worden volgens velen. Black Ops III zal ook wederom op deze engine draaien. Dit heeft ontwikkelaar TreyArch bevestigd. Wel benadrukte de ontwikkelaar dat de engine flink is aangepast. Zo is er een nieuwe render-techniek welke ervoor zorgt dat de game grafisch flink sterker is dan Black Ops II. Multiplayer director Dan Bunting:
Engines are funny things. People used to talk about game engines as if it was a singular product that the game’s built on. But engines are really collections of tech that have some very basic, fundamental architecture to them. The core architecture of the game is still based on the technologies that it’s been built off of, but most engines in the game industry, for large scale games, have all come from a lineage back to an earlier game engine.
Engines these days, especially for games of this kind of scope, are very varied, so that each component of the game has its own engine in a lot of ways. The engine itself, what the people refer to the as the engine, is the technology the studio develops along the way.
