October 2026

  1. Simpler class builder

    The builder shows one slot at a time with a row per slot, the stats of the build at a glance and an Undo button. Phones get a menu, and long pages fold their detail.

  2. Patch notes: Smaller update and DMZ cash rewards

    A smaller update with Multiplayer and DMZ fixes, the Infected Halloween mode and higher DMZ cash rewards for Side Ops and mission steps.

  3. Patch notes: Fixes and Possession mode

    Fixes for Multiplayer and DMZ, higher XP earn rates in several Multiplayer modes and higher DMZ cash rewards, with no values given, and the Possession Halloween mode.

  4. Bare address opens the MW4 builder

    The site address without a path now opens the MW4 class builder. The list of games moved to /games/.

  5. Community-reported weapon stats

    Base stats for every weapon (movement, handling, recoil, bullets, ammo) and the changes each attachment makes to them, read from CODMunity on 28 October 2026. They appear in the builder, on weapon pages and on popular builds. Community-reported and unverified; Activision has not published them.

  6. Popular builds

    A page of builds listed by CODMunity for Multiplayer and DMZ, with build codes, Multiplayer pick rates and an Open in the builder link for each build. Community-reported and unverified.

  7. More attachment names, with pictures

    The community-reported attachment list grew to 615 names from ggranked and CODMunity, 611 of them with a picture. Names and pictures are not published by Activision.

  8. Tier lists drawn as boards

    The two community tier lists are drawn as tier boards with a weapon card in each tier. The lists keep their own methods and dates.

  9. Patch notes: First weapon tuning update

    The first weapon tuning update. Infinity Ward says it focused on normalizing hit location damage and on SMG performance; the tables list every weapon changed, with Apex and attachment changes.

  10. Attachment names picked from cards

    In the builder, attachment names are chosen from cards instead of a text list.

  11. Each game has its own section

    The MW4 pages moved under /mw4/ and the site root became a list of games, so a later title can sit next to MW4. Old addresses redirect to the new ones.

  12. Analytics and privacy page

    One Google Analytics 4 tag was added to every page. The privacy page describes what it collects and how to turn it off.

  13. Patch notes: Fixes, gameplay adjustments and XP

    Fixes and gameplay adjustments, a rollback of the Search and Destroy bomb stretching fix, and XP for 1 kill raised from 100 to 300 in Search and Destroy and Collateral.

  14. Community tier lists

    Two community tier lists were added: a Multiplayer ranking by time to kill from ggranked and a DMZ PvP list from DMZ Radar. Weapon pages show the community tier on one line, and the builder shows a tier badge in the weapon picker.

  15. Attachment names and official artwork

    155 community-reported attachment names were added (the list was replaced by a larger one on 28 October). Every weapon, perk, tactical, lethal, field upgrade and killstreak got a picture cropped from Activision's launch blog post, and an icon credits page was added.

  16. COD Loadout opens

    The MW4 class builder, a page for each weapon with Activision's published fire rate, magazine, reserve and unlock level, the attachment types and Gunsmith rules, all Apex Attachments, and perks and equipment.

  17. Patch notes: Fixes and improvements

    Fixes and improvements for Multiplayer and DMZ, including Hijack spawns, Search and Destroy defusing and Gunsmith prestige resets.

  18. Patch notes: Launch day update

    Launch day fixes for stability, UI and DMZ, with new use counts for Parachutes and Gas Masks and a note that Apex Attachments from the Beta will return.

  19. Patch notes: Pre-launch update

    Pre-launch notes on weapon, perk, movement, spawn, Killstreak and equipment tuning since the Beta, with DMZ fixes made on October 20 and 21. UAV health goes from 100 to 150.
