The gap between MW3 and the shared Call of Duty launcher is wide. The launcher app, which now carries Warzone and the newer Black Ops titles, showed 15,356 players at the same check, and the Warzone concurrency figures come from that same combined listing.
MW3 Live Player Count By Month
Monthly averages fell for four straight months from August 2025 to a floor of 1,614.52 in December 2025. The line then turned, with small monthly gains through the first half of 2026.
July 2026 broke the pattern at 2,867.80, and August 2026 more than doubled again to 6,085.18. That month also produced a 14,444 peak, more than triple July’s 3,941.

What happened in August 2026
Three dated events fall inside that month. SteamDB logged the lowest Steam price ever recorded for the game, $17.49 at 75% off, on 11 August 2026.
Activision then ran the Modern Warfare 4 Early Access Beta from 21 August and the Open Beta from 28 August to 1 September, per the Call of Duty blog. The timing overlaps; none of these sources states that either event moved the MW3 count.
What The MW3 Player Count Leaves Out
Modern Warfare III sells on PlayStation 5, PlayStation 4, Xbox Series X|S, Xbox One and PC through Steam, Battle.net and the Microsoft Store. Sony, Microsoft and Activision publish no concurrent player counts for any of them.
Every figure on this page is Steam only. Steam counts client sessions, which is a different measurement from server population, and games that expose a server browser show the difference clearly, as the Battlefield 4 population readings demonstrate.
Steam concurrency also predates nothing here. MW3 sat inside the Call of Duty HQ launcher until 29 July 2025, so no separate Steam count exists for the game before that date. Publishers who report their own totals, such as Ubisoft in the Rainbow Six Siege active-player disclosures, give a fuller picture than any store counter can. Activision does not.
MW3 Player Data From Steam Achievements
Valve publishes the share of all tracked players who have unlocked each of the game’s 39 achievements. It is the only public dataset showing what MW3 owners on Steam actually do.
Reaching multiplayer level 55 sits at 55.7%, the highest mark on the list. Campaign completion trails it at 33.0%, and only 3.3% have finished the campaign on Veteran.
Zombies numbers thin out fast. A first successful Exfil reaches 39.9%, but completing Act III of Modern Warfare Zombies drops to 6.3%.
| Achievement | Requirement | Share of players |
|---|---|---|
| The First Step | Reach level 55 | 55.7% |
| Death Row | Kill 12 enemies in the panopticon descent | 43.2% |
| And So It Begins | Exfil successfully in MWZ | 39.9% |
| Never Bury Your Enemies Alive | Complete the campaign | 33.0% |
| Hired Gun | Complete 20 contracts in MWZ | 24.8% |
| Conqueror | Defeat a Warlord in MWZ | 13.1% |
| The End? | Complete Act III in MWZ | 6.3% |
| 141 Ready | Complete the campaign on Veteran | 3.3% |

MW3 2023 Player Count vs MW3 2011
Two different games share the MW3 name, and both still run on Steam. The 2011 Modern Warfare 3 multiplayer client held 51 players at the 7 September 2026 check, with a 222 peak over the prior 24 hours.
Its record stands at 55,900, set in September 2012. Comparing the same month across years strips out seasonality: August averages fell from 18,765.86 in 2012 to 86.33 in 2025, then edged up to 88.80 in August 2026.
| Reading | Concurrent Steam players |
|---|---|
| Players in game at check | 51 |
| 24-hour peak | 222 |
| August 2026 average | 88.80 |

A fifteen-year decline curve like this one is normal for premium shooters without a free entry point. Titles that went free-to-play, including Overwatch 2 across its Steam era and Apex Legends on its Steam listing, hold six-figure numbers far longer.
MW3 Statistics On Reviews, Price And Release Dates
Steam user reviews for the standalone MW3 app run 45.38% positive across roughly 20,000 reviews, as counted by SteamDB in September 2026. Steam records each review as either positive or negative, so the rest are negative.
Sledgehammer Games developed the title and Activision published it on 10 November 2023. Microsoft added it to Xbox Game Pass on console, PC and Ultimate on 24 July 2024, per Xbox Wire.
Circana’s US monthly market reports ranked Modern Warfare III the best-selling game of November 2023 in dollar sales and the second best-selling game of 2023 overall, behind Hogwarts Legacy. The next entry in the series, Modern Warfare 4, is dated 23 October 2026 on the Call of Duty blog.
Activision’s other current shooters are tracked separately, including the mobile branch covered in these Call of Duty Mobile download and player figures. Long-tail Steam behaviour of this kind also shows up in older multiplayer titles like Battlefield 2042 and Among Us.
