The upcoming Call of Duty: Modern Warfare 4 beta will feature a new matchmaking system designed to strike a better balance between connection quality, skill, and other lobby-building factors. Activision has also confirmed that open matchmaking playlists will run alongside the standard system so the studio can gather data from both approaches.
In a detailed clarification posted on the official Call of Duty social channels, the team addressed ongoing community debate about skill-based matchmaking. The statement emphasized that the beta’s system is not a return to the tighter skill matching seen in some recent titles. Connection quality remains a top priority. At the same time, the post noted that every Call of Duty game, including older entries such as Black Ops 1 and Black Ops 2, has considered skill to some degree when forming lobbies.
Matchmaking has never been a single switch, the team explained. Factors including player location, time of day, playlist selection, party size, platform, cross-play settings, and overall population all influence how matches are built. The new system aims to weigh these elements more effectively to produce consistently enjoyable games.
To help evaluate the changes, open matchmaking will be available during the beta. This dual approach allows Infinity Ward and Activision to compare player behavior, retention, and feedback between the revised standard system and fully open lobbies.
Activision also shared performance data from open matchmaking experiments in Black Ops 6. According to the company, for 80 percent of players from launch through Season 4, open matchmaking produced notably worse results than the standard system. Quit rates were 32.7 percent higher, kills per minute dropped 14.4 percent, win rates fell 5.3 percent, and "Not Fun" ratings rose 59.2 percent. On the popular Nuketown 24/7 playlist, quit rates jumped 141 percent, with the most competitive players leaving one in every three matches.
Lobby disbanding was another issue highlighted. Roughly half of players leave after the first match in open settings, and by the third game almost none of the original lobby remains. Backfilling then takes longer, whereas starting fresh can get players into a new match faster while still prioritizing ping.
The beta will give the studio a large volume of real-world data on how the new system performs under load and how players respond when given the choice between standard and open playlists. Feedback collected during the two beta weekends is expected to influence the final matchmaking settings at launch.
Matchmaking remains one of the most discussed topics in the Call of Duty community. By running both systems side by side and publishing some of the underlying data, Activision is attempting to move the conversation beyond simple preferences and toward measurable outcomes. How players actually behave in the Modern Warfare 4 beta will determine whether the new approach feels like a meaningful improvement or simply another iteration of the same long-running debate.
