Pre-launch download size information for Call of Duty: Modern Warfare IV has emerged. Current platform listings show the Xbox version at approximately 194.32 GB and the Nintendo Switch 2 version at 77.304 GB. The game is scheduled to launch on PlayStation 5, Xbox Series X/S, Windows PC, and Nintendo Switch 2 on October 23, 2026.
These figures come from current listings for their respective platforms and cannot yet determine the full final download requirements for each mode. The Xbox version is expected to offer separate downloads for different parts of the game, similar to the PS5 version.
The PS5 platform lists a 28.702 GB base game, along with separate content packs for Campaign, Multiplayer, DMZ, and shared content. The Warzone content pack is listed at 42.033 GB, and the Campaign content pack at 42.171 GB. Available information does not clarify whether these content packs overlap or specify which packs are required for each mode, so the listed sizes cannot be simply added together to determine the exact installation requirements for PS5.
Most content packs in the list have version number 01.001.000; the base game is 01.109.000, and the Warzone content pack is 01.034.000. Although DMZ Content Pack 2 lists version 01.000.000, it currently has no download size.
PC system requirements specify an SSD and 115 GB of available space at launch; minimum RAM is 8 GB, with 16 GB recommended. Developed by Infinity Ward and published by Activision, the story involves a geopolitical crisis triggered by a full-scale invasion of the Korean Peninsula, covert operations, and returning characters drawn into international conflict.
