Every lever that should widen a player pool was pulled for the Modern Warfare 4 Open Beta. It was free. It ran on PlayStation 5, Xbox Series X and S, Battle.net, Steam, Xbox on PC and Switch 2. It carried core 6v6, Ground War on Combat Outpost, Kill Block, a campaign mission and a Warzone map. No pre-order was required. On September 14 CharlieIntel posted what Circana's player tracker made of that weekend in the US, and the answer was modest: sixth place on PlayStation 5, fourth on Xbox Series X and S, with Black Ops 7 and Warzone inside the Call of Duty app still pulling a higher player count than the new game's beta.
Reported, not confirmed. The chart positions and the comparison come from a single CharlieIntel post reading Circana's player tracker, no raw numbers were published, and Activision has released no participation figures of its own. The direction is consistent with what the Steam peaks showed two weeks ago, but a chart position is a ranking, not a headcount.
What the tracker says
- PlayStation 5 The MW4 Open Beta peaked at number six in the US for the week of August 29 to September 5.
- Xbox Series X and S It peaked at number four over the same week, its better of the two console showings.
- Against the incumbent Black Ops 7 and Warzone, running inside the Call of Duty app, held a higher player count than the beta across that week.
- What is absent No raw player numbers, no breakdown by mode, and no statement of what the tracker counts. The post gives rankings and a relative comparison, nothing more.
This lands on top of the Steam half of the same story. Two weeks ago the counting that mattered was PC: the free Open Beta's concurrent peak came in a shade under the peak the pre-order gated Early Access weekend had set a week earlier, which is the wrong direction for a weekend that removed the paywall. That read had one honest weakness, and we said so at the time: Steam is one storefront, and the console numbers were not public. They are now, at least as a ranking, and they point the same way.
Why Hardcore SnD cares
Search and Destroy is the mode that breaks first when a population thins. It needs twelve committed players who want the same ruleset at the same moment, with no respawns to paper over a bad match. Hardcore variants sit one layer below that, which is why they show up late and get cut early in every Call of Duty life cycle. The MW4 beta never shipped a Hardcore playlist at all, so the only question that matters is whether the launch pool is deep enough to justify one.
- Console is the pool The overwhelming majority of Call of Duty SnD players are on PS5 and Xbox. A PC-only signal was a slice; a console signal is the thing itself.
- Queue times A shallower launch pool means longer searches for SnD specifically, and worse geographic matching inside the searches that do fill.
- Hardcore availability Hardcore playlists get merged or cut when the population cannot carry them. Fewer players at launch means a longer wait for a dedicated Hardcore SnD queue, if it arrives.
- Scrim partners Pickup games and practice lobbies come out of the same pool. A thinner ceiling means fewer teams to run on a weeknight.
A beta ranking is not a launch population. It is the second warning light on the same dashboard, and both are now lit.
What is not confirmed
Almost all of the detail. Circana has not published these figures in a form we could read, so the whole claim rests on one CharlieIntel post summarizing a tracker. The post does not say whether the player count it compares is concurrent players, daily players or weekly players, and those three measures tell very different stories about the same weekend. Activision has released no participation numbers for either beta weekend. The comparison is also not clean: a brand new beta is measured against two live games with a year of installed base behind them, on a chart that ranks rather than counts. Read it as a signal about interest, not a verdict on how many people will be queuing for SnD on October 23.
What would verify it
Three things would move this. Circana publishing the underlying tracker data, or a B tier outlet running its own accounting with the methodology stated, would turn one post into reporting. An Activision or Infinity Ward figure for beta participation would settle it outright and is the only thing that could make it confirmed. And the real test is the fortnight after October 23: if SnD and Hardcore searches on console fill fast and a dedicated Hardcore playlist lands early, the beta charts were noise. If they crawl, this was the signal.
