Top trending games on Steam: September 26
Counter-Strike 2: Valve’s competitive tactical shooter and successor to CS:GO. Thirty-day volume fell 3.28% to 1,331,274 concurrent players against a 1,420,896 baseline, with demand index 73.8 versus 76.3. No widely reported September 26, 2026 patch headline appeared in search; rank 1 reflects habitual weekend PC traffic.
Dota 2: MOBA from Valve with a deep esports calendar. Thirty-day volume rose 14.51% to 981,123 players versus an 860,019 baseline, index 86.0 vs 75.1, the strongest positive move among the top 3. No single Sept 26 news item was required to explain sustained MOBA concurrency.
PUBG: BATTLEGROUNDS: Battle royale shooter from Krafton. Thirty-day volume declined 2.02% to 771,621 vs 792,142 baseline, index 19.4 vs 19.8. No widely reported trigger identified for September 26, 2026.
WARDOGS: 100-player, three-team tactical warfare FPS from BULKHEAD and Team17, in Steam Early Access since September 10, 2026 at $39.99. Search coverage points to ongoing Early Access play rather than a Sept 26 launch event.
Bongo Cat: Free desktop companion game from Irox Games where keystrokes feed a taskbar cat. Rank 5 likely reflects meme status and multiplayer lobby features after 2026 content updates; no Sept 26-specific announcement surfaced.
Apex Legends: Respawn battle royale (listed without trademark symbols per house style). Rank improved from yesterday’s 8 to today’s 6. No widely reported September 26, 2026 balance patch dominated headlines in fetch results.
Valheim: Iron Gate survival co-op. Slid one rank from 6 to 7 with no widely reported trigger identified for September 26, 2026.
Delta Force: Team Jade tactical shooter that charted as high as rank 14 on September 23, 2026 with roughly 170,000 peak concurrent players in third-party Steam charts. Entering today’s top 10 at 8 replaces Marvel Rivals; September season updates kept the title in rotation.
FiveM: Grand Theft Auto V multiplayer modification framework. Dropped from 7 to 9. No widely reported trigger identified for September 26, 2026.
Aniimo: Pawprint Studio creature-catching open-world RPG, free to play on Steam from mid-September 2026 with mobile launch September 23. Rank 10 reflects launch-week curiosity after the September 16, 2026 global PC release.

What changed on Steam since yesterday
New entrant: Delta Force at rank 8. Drop-off: Marvel Rivals (was 10). Movers include Apex Legends 8 to 6, Valheim 6 to 7, FiveM 7 to 9, and Aniimo 9 to 10. Counter-Strike 2, Dota 2, PUBG, WARDOGS, and Bongo Cat held ranks 1 through 5. The board therefore mixes evergreen shooters, a mid-September Early Access FPS, a viral casual title, a returning tactical shooter, and a fresh RPG launch.
What today's Steam trends reveal
Steam’s September 26 list shows how launch windows stack against evergreen MOBA and shooter traffic. Dota 2’s 14.51% thirty-day volume gain contrasts with CS2’s 3.28% dip, yet both remain in the top 2 slots, which tells analytics teams that rank and momentum can diverge. WARDOGS at 4 proves a September 10 Early Access price point can keep a 100-player warfare title visible two weeks later. Delta Force’s return to public charts after a September 23 peak near 170,000 players explains its top-10 re-entry without a brand-new release date. Publishers tracking concurrency should log both rank and volume baselines via the Steam Most Played API. Mobile-first studios comparing PC legs can read the Sensor Tower alternatives roundup for cross-store context.
