Call of Duty MW4Credit: ActivisionThe beta for Call of Duty: Modern Warfare 4 arrives this week and it's coming with what feels like something close to the complete gaming experience. We'd already been treated to the preview of the single-player campaign. But on Wednesday the multiplayer trailer dropped with details about that portion of the beta experience. Let's talk Call of Duty.Modern Warfare 4 Beta Key FactsDetailInfoEarly access betaFriday, Aug. 21 through Aug. 25Early access requirementPre-orderEarly access platformsPlayStation 5, Xbox Series X and S, PCOpen betaFriday, Aug. 28 through Sept. 1Open beta requirementNoneOpen beta platformsAll, including Nintendo Switch 2Call of Duty: NEXTAug. 21, immediately before early access opensMultiplayer mapsRooftops, Silkworm, Transit 213, Cachette, Lithium, Kill BlockWarzoneZodiac, ResurgenceGround WarImjin Farmland, Wolves StadiumThe DreadnoughtAston Martin collaboration vehicleFull releaseFriday, Oct. 23, 2026One thing to know before Friday. The Aug. 21 weekend is early access and it requires a pre-order, on PlayStation 5, Xbox Series X and S, and PC. The genuinely open weekend runs Aug. 28 through Sept. 1, needs no pre-order, and is the first one that includes Nintendo Switch 2. Call of Duty: NEXT airs Friday immediately before the early access servers open.

The trailers look excellent and the expansive beta should go a long way toward building momentum toward the full release in October.The Dreadnought has me excited. Commanding a vehicle with that much power and style is an attractive concept that I can't wait to explore, even though I'm more of a Free-for-All guy. And I don't imagine the Dreadnought will be as fun to control in that mode.More Video Game CoverageGears Of War: E-Day Beta — How To Play EarlyCall Of Duty: Black Ops 7 Season 04 Reloaded Patch Notes: Nicolas Cage, New MapsEA UFC 6: Release Date, Pre-Order Info, Beta Details and New FeaturesEvery Map and Mode in the Modern Warfare 4 BetaPlay Puzzles & Games on ForbesContent list per Activision.TypeIncludedMapRooftopsMapSilkwormMapTransit 213MapCachetteMapLithiumMapKill BlockModeTeam DeathmatchModeDominationModeHardpointModeKill ConfirmedModeInflationModeSearch & DestroyModeGunfight, 3v3ModeKill Block, 10v10ModeMobility CourseModeHijackModeCombat OutpostWarzoneZodiac, ResurgenceGround WarImjin FarmlandGround WarWolves StadiumBe on the lookout for more details and info on CODMW4 once the beta drops and especially once the full release is here.
