Sources: 62. Developments: 8. The Call of Duty: Modern Warfare 4 multiplayer beta will run in two phases in August 2026. Early‑access runs from 21 to 25 August for players who pre‑order the digital Standard or Vault editions on PC, PlayStation 5 and Xbox Series X|S, followed by an open beta from 28 August to 1 September that includes Nintendo Switch 2 with no pre‑order requirement. The beta will feature 19 weapons, classic modes such as 3‑vs‑3 Gunfight and 6‑vs‑6 Ground War, a Training Mobility Course, and the new “Kill Block” arena with over 500 layout configurations supporting 3‑vs‑3 and 10‑vs‑10 matches. Pre‑order customers receive the Gilded Pearl camouflage pack and a special Black Ops 7 challenge that can unlock the uniquely numbered “Gilded Ruin” skin for the first 100,000 players. New details regarding the single-player campaign reveal a narrative set against a large‑scale conflict triggered by a North Korean invasion of the Korean peninsula. The story features series veteran Captain Price and the return of character Valeria Garza, who will form an alliance with Price during a mission in Paris as they hunt for Makarov and an artillery system known as “Archer”. In multiplayer development, an alpha build of the “Kill Block” mode was showcased at Fanatics Fest, highlighting its modular building blocks. Developers noted that early testing has helped identify technical bugs, including issues involving smoke grenades and DMRs. The full game is slated for worldwide release on 23 October 2026 across PC, PS5, Xbox Series X|S and Switch 2. Pre-order customers will also receive seven days of early access to story content. ## Timeline ### 2026-08-11: Call of Duty: Modern Warfare 4 reveals campaign teaser and Kill Block mode Activision reveals campaign details and the new “Kill Block” multiplayer mode for Call of Duty: Modern Warfare 4, scheduled for release in October 2026. 9 sources. https://clstr.news/cluster/call-of-duty-modern-warfare-4-reveals-campaign-teaser-and-kill-block-mode ### 2026-08-07: Activision schedules Call of Duty NEXT 2026 livestream for August 21 Activision set the Call of Duty NEXT 2026 livestream for 21 August, revealing Modern Warfare 4 gameplay and outlining beta and release dates. 6 sources. https://clstr.news/cluster/activision-schedules-call-of-duty-next-2026-livestream-for-august-21 ### 2026-08-05: Call of Duty: Modern Warfare 4 trailer released and Monster Energy promotion announced Infinity Ward unveiled a Modern Warfare 4 campaign trailer, and Monster Energy will sell branded cans with QR codes for in‑game rewards ahead of the October 23, 2026 release. 2 sources. https://clstr.news/cluster/call-of-duty-modern-warfare-4-trailer-released-and-monster-energy-promotion-announced ### 2026-07-28: Discord Nitro Early Access Beta for Call of Duty: Modern Warfare 4 Rumored A leak suggests Discord Nitro subscribers could get early‑access beta codes and an exclusive weapon blueprint for Call of Duty: Modern Warfare 4, though neither Activision nor Discord has confirmed the claim. 2 sources. https://clstr.news/cluster/discord-nitro-early-access-beta-for-call-of-duty-modern-warfare-4-rumored ### 2026-07-25: Activision Announces Modern Warfare 4 Beta Dates and Pre‑order Bonus Activision set Modern Warfare 4 beta dates (Aug 21‑25 early access, Aug 28‑Sep 1 open) and announced a pre‑order camouflage bonus, with the beta launching right after the Aug 21 Call of Duty: NEXT livestream. 2 sources. https://clstr.news/cluster/activision-announces-modern-warfare-4-beta-dates-and-preorder-bonus ### 2026-07-23: Call of Duty Modern Warfare 4 beta dates announced, featuring new Kill Block mode Modern Warfare 4 beta dates set: early access Aug 21‑25 for pre‑orders, open beta Aug 28‑Sep 1, new Kill Block map mode, no Game Pass benefits. 3 sources. https://clstr.news/cluster/call-of-duty-announces-modern-warfare-4-beta-dates-and-black-ops-7-matchmaking-overhaul ### 2026-07-20: Call of Duty: Modern Warfare 4 beta dates set for August 2026 Call of Duty: Modern Warfare 4's beta runs 21‑25 Aug for pre‑orderers and 28 Aug‑1 Sept open to all, including Nintendo Switch 2, ahead of its 23 Oct release. 43 sources. https://clstr.news/cluster/activision-sets-open-beta-dates-for-call-of-duty-modern-warfare-4 ### 2026-06-30: Xbox confirms Call of Duty Modern Warfare 4 will not be on Game Pass Xbox announces Call of Duty: Modern Warfare 4 (Oct 23) will not launch on Game Pass, reflecting a policy shift under CEO Asha Sharma to protect full‑price sales and pause third‑party deals. 2 sources. https://clstr.news/cluster/xbox-confirms-call-of-duty-modern-warfare-4-will-not-be-on-game-pass --- Cite as: Call of Duty MW4 beta and campaign details updated.
