Call of Duty NEXT takes place on 21 August with live Modern Warfare 4 multiplayer. The early-access beta begins after the broadcast and runs through 25 August. An open beta follows from 28 August through 1 September.
The first weekend supports Xbox Series consoles, PlayStation 5, and PC. Nintendo Switch 2 joins during the open weekend. The beta includes new operators, several modes, and as many as nineteen weapons.

NEXT shows complete Modern Warfare 4 multiplayer matches
Call of Duty NEXT will include live gameplay and developer explanations. The broadcast focuses on Modern Warfare 4 multiplayer before public testing begins. New maps, modes, and operators will appear during the presentation. A live demonstration provides more detail than a short trailer. Viewers examine movement, weapon handling, and objective rules. They also compare several matches rather than one edited sequence.
Developers plan to discuss the content available during the beta. That information helps players decide what to test first. It also separates launch content from features limited to the trial period. The beta begins immediately after the NEXT event on 21 August. This order moves players directly from the presentation into testing. Any final start time will depend on the announced regional schedule.
The first beta weekend supports three platforms. Weekend One runs from 21 through 25 August. It is available to eligible players on Xbox Series X or S, PlayStation 5, and PC. Access depends on a qualifying preorder or beta code. PC support covers Battle.net, Xbox on PC, and Steam. Each service requires the correct account connections. Download size and server demand may differ between platforms.
Early access gives the developers four days of active match data. Developers measure connection failures, movement across maps, and weapon use in many matches. Player reports also identify issues that statistics may not explain.
This weekend is not the complete public test. Some users will wait until 28 August. Results from early access may support minor changes before the open period begins.
The open beta also supports Nintendo Switch 2. Weekend Two begins on 28 August and ends on 1 September. It is open across supported platforms without a preorder requirement. Nintendo Switch 2 players join Modern Warfare 4 testing during this period. Switch 2 preorders begin on 26 August, two days before the open beta. Participation in the open weekend does not require that purchase. The test therefore allows players to examine performance first.
Cross-platform testing reveals differences in controls and network conditions. It also increases the number of available opponents. Matchmaking has a broader group during busy regional hours. The second weekend provides the widest test before the 23 October release. Problems found there still require development time. The launch build will not include every requested change.
| Stage | Dates | Access |
|---|---|---|
| Call of Duty NEXT | 21 August | Broadcast |
| Early-access beta | 21-25 August | Eligible players |
| Open beta | 28 August-1 September | All supported platforms |
| Game launch | 23 October | Paid release |
The beta includes small and large team modes
Modern Warfare 4 includes compact three-versus-three fights and larger tactical battles. Some large modes use vehicles, including tanks. The difference places separate demands on maps and equipment. Search and Destroy returns as a round-based objective mode. Kill Block joins as a new option with different scoring rules. A Training Mobility Course helps players learn basic movement before regular matches.
Up to nineteen weapons will be available during the beta. That number gives players several roles without revealing every launch weapon. Attachments and unlock speed will shape the early test. Small fights expose movement and close-range balance quickly.
Large battles test visibility, travel distance, and vehicle pressure. Both formats provide distinct information for the development team.
The full game launches in October. Modern Warfare 4 launches globally on 23 October 2026. The release covers Xbox Series consoles, PlayStation 5, PC, and Nintendo Switch 2. The beta occurs about two months before that date. A test build does not represent every final menu or balance value. Developers may change weapon damage, movement, and map details afterward. Confirmed launch features remain separate from temporary settings.
Progress from a beta does not always transfer into the full game. The published beta information explains any available rewards. Those terms determine whether time spent on unlocks carries forward. The launch date provides a fixed deadline for the current testing cycle. Later seasons and updates remain separate from the October product. The August beta focuses on multiplayer stability and balance.
The schedule includes early access and a public beta
Eligible early-access users begin after NEXT on 21 August. Everyone else joins the open weekend from 28 August. Nintendo Switch 2 appears only in the second window. These dates avoid a confusing claim that every platform starts together. They also distinguish the broadcast from the public test. NEXT shows the game before the first servers open.
Players use the Mobility Course before entering competitive modes. Testing several weapons also provides better evidence than repeating one loadout. Reports become more useful when they name a map, mode, and platform. Modern Warfare 4 still has two months before release after the open beta. The August sessions provide data rather than a final verdict. Their main value comes from actual matches across several systems.
