Modern Warfare 4 Open Beta Starts August 28 With Campaign and Warzone

The open weekend starts August 28

Call of Duty: Modern Warfare 4 will open its beta to all players on August 28 at 10 a.m. Pacific time. The test is scheduled to run through September 1 at 10 a.m. Pacific on PlayStation 5, Xbox Series consoles, Nintendo Switch 2, Steam, Battle.net, and Xbox on PC. Activision says no preorder is required for the open portion.

The public weekend follows an early-access period that ran from August 21 through August 25. That first test gave the developers a larger feedback sample before the doors open more widely. Official patch notes say the team is examining spawn behavior, time-to-kill, and movement, though further changes may continue beyond the beta.

Six 6v6 maps form the multiplayer core

The open beta includes six maps built for standard 6v6 play. The available playlists rotate through familiar Call of Duty structures alongside Kill Block, a mode that changes the value of each elimination by making dropped blocks part of the score. A Ground War option expands the scale for players who prefer vehicles and larger teams.

Activision is making 22 weapons available during the test, giving players enough room to compare categories and experiment with loadouts. Eight beta rewards can also be earned and carried into the full game. The progression ceiling and playlist rotation may shift during a live test, so players should treat the official beta page and in-game notices as the final schedule.

Campaign and Warzone are part of the sample

This beta is broader than a conventional multiplayer weekend. It includes Entrenched, a mission from the Modern Warfare 4 campaign, as well as a Warzone Resurgence experience called Zodiac. The structure lets Activision test three different parts of the Call of Duty ecosystem while giving players a clearer sense of what the October release contains.

Entrenched is especially useful for players who do not judge Call of Duty by competitive multiplayer alone. A campaign mission can reveal pacing, enemy behavior, visual clarity, and checkpoint design in ways that a small arena cannot. The Warzone playlist tests a different problem: how the new weapons and movement interact with a battle-royale ruleset and a much larger space.

What the beta can and cannot prove

A beta can expose server problems, dominant weapons, confusing spawns, and mechanical friction. It cannot provide a final performance verdict. Download size, shader compilation, driver maturity, network conditions, and platform-specific settings can all change before launch. Players troubleshooting hitches should separate connection instability from local frame-time stutter before drawing conclusions.

The same caution applies to balance. A weapon that dominates during one weekend may be adjusted rapidly, while a map that feels chaotic in a new-player lobby may settle once routes become familiar. The most valuable feedback will identify repeatable problems rather than assume every early frustration is permanent.

The beta tests all three modes

Modern Warfare 4’s open beta is unusually useful because it samples multiplayer, campaign, and Warzone instead of presenting one narrow slice. That makes the download more informative for players deciding whether the full package suits them, and it gives the developers several kinds of real-world load and balance data.

The test runs only through September 1, with the full game currently scheduled for October 23. Anyone interested should verify the start time in their region and expect live playlists or tuning to change during the weekend. The point is to test a moving build, not to treat it as a finished review copy.
