    Meilleure citation de Call of Duty: Building the War Machine - History of the IW Engine

    “

    The franchise has transitioned from a historical 'composite impression' of war to a 'symbolic dog whistle' for modern heroism. Early on, it was about the collective courage of ordinary men; now, it’s about the hyper-competence of the individual.

    Foire aux questions

    The initial Call of Duty was a calculated reaction to a market filled with generic World War II shooters. Instead of following the popular 'lone wolf' design where the player is the only relevant entity, the game focused on a 'No Soldier Fights Alone' philosophy. This approach aimed to portray war as a collective experience and a massive push rather than a solo power fantasy, which dictated the technical requirements for the game's development.

    The lineage of the Call of Duty engine began with a modified version of id Tech 3, the same technology used for Quake III Arena. However, a major shift occurred with the development of Call of Duty 2 in 2005. Infinity Ward rewrote significant portions of the codebase, including the rendering, lighting, and tools. According to Mark Rubin, the studio eventually reached a point where almost none of the original Quake code remained in their proprietary engine.

    Call of Duty 2 was the pivotal moment where the IW engine truly diverged from its id Tech 3 origins to become its own proprietary beast. To support the vision of dozens of soldiers on screen without performance issues, Infinity Ward heavily modified the engine's core systems. This technical evolution allowed the developers to move away from the limitations of existing tech and build a custom engine tailored specifically for the scale of the Call of Duty franchise.
