TBH: Task Bar Hero at rank 2 is the headline on Steam's most-played chart for June 18, 2026, with more than 460,000 concurrent players pushing it past Dota 2 and every other live-service title except Counter-Strike 2. Coverage of the May 27 launch credits a viral idle-RPG loop that runs in the taskbar and lets players sell earned items on the Steam Community Market, though Kotaku and Notebookcheck also flag botting allegations and mixed reviews. This is the first Steam most-played roundup in the Trends MCP daily archive, so there is no prior same-platform post to compare ranks against; the clearest shift versus a typical chart is an idle game cracking the top three alongside Valve's twin anchors.
Top trending games on Steam, June 18
-
Counter-Strike 2: Valve's free competitive FPS and perennial Steam chart leader. Coverage on June 18 points to its usual weekend-evening player surge rather than a new patch; SteamCharts data shows average concurrents sliding from roughly 1.08 million in February 2026 toward the low 930,000s by May, yet CS2 still clears every other title by a wide margin. Steam concurrent-player volume was flat over the past 7 days and down about 4% over 30 days per Trends MCP growth data.
-
TBH: Task Bar Hero: A free idle RPG from Tesseract Studio that launched May 27, 2026 and runs in a small taskbar window while heroes farm loot in the background. Notebookcheck on June 17 reported peaks above 500,000 concurrent players, driven by players chasing Steam Wallet credit from marketable drops; developers restricted tradable items after Valve flagged server load on May 31.
-
Dota 2: Valve's free MOBA and a fixture in Steam's top three for years. No major June 18 patch cycle was reported; the title holds its rank on baseline daily engagement from Southeast Asia and European evening peaks. Steam player volume was flat over 7 days and down less than 1% over 30 days per Trends MCP.
-
PUBG: BATTLEGROUNDS: Krafton's battle royale, still a top-ten Steam regular. PUBG's June 16 store update rolled out Black Market 2026 and a Double G-Coin promotion tied to the PNC 2026 esports event, giving lapsed squads a reason to log back in this week.
-
Bongo Cat: A free desktop pet idle game where keystrokes trigger bongo beats on the taskbar. GameGrin reported a 2026 Summer Event starting June 16 with 20 limited-time cosmetic drops running through July 14, which lines up with June player counts climbing about 9% month to date.
-
Path of Exile 2: Grinding Gear Games' early-access action RPG. Return of the Ancients launched May 29 with a free Steam weekend that pushed concurrent players above 421,000; three weeks later the title still rides that endgame expansion without a fresh June 18 patch.
-
Destiny 2: Bungie's live-service shooter. The June 9 Monument of Triumph final update drove Steam concurrents to 167,867, the highest figure in two years per PCGamesN, as players returned for tiered raid gear and a community "server slam" after support ended.
-
FiveM: A GTA V multiplayer modification framework popular for roleplay servers. FiveM has ranked in Steam's top 15 since its December 2025 Steam listing; June traffic reflects steady RP server populations rather than a single June 18 event.
-
Limbus Company: Project Moon's free-to-play turn-based RPG. The June 11 Chapter 9.5 Mnestic Experience update and ongoing hotfixes for Unity upgrade crashes kept the player base active through mid-June.
-
Wallpaper Engine: A desktop customization app for animated wallpapers. A Kaspersky report published June 16 flagged malware hidden in Steam Workshop application-type wallpapers, which drew security coverage but did not appear to dent the app's core concurrent-player floor.
-
Warframe: Digital Extremes' free sci-fi action RPG. Update 43: Jade Shadows: Constellations launched June 17 with the Sirius and Orion Warframe and a new story quest.
-
Marvel Rivals: NetEase's team-based hero shooter holding 70,000 to 90,000 Steam concurrents in June. No named seasonal event was reported for June 18.
-
Apex Legends™: Respawn's battle royale in Season 29: Overclocked. Ranked Ladder 6 ran June 18 through June 21 alongside a Diamond solo-queue matchmaking test through June 23.
-
Slay the Spire 2: Mega Crit's early-access deckbuilder. Beta patch v0.107.0 on June 4 buffed Monarch's Gaze and fixed stability bugs, keeping six-figure concurrents alive.
-
Dead by Daylight: Behaviour Interactive's asymmetric horror game. A free Steam week started June 16 alongside a Jason Voorhees chapter tied to the June 14 tenth-anniversary event.
-
Rust: Facepunch's survival sandbox. The June 4 Built Different force wipe added a new player model, M16A2 rifle, and Ballistic Armour set.
-
Overwatch®: Blizzard's team shooter on Steam via Battle.net. February 2026's Reign of Talon relaunch still props up mid-five-figure June concurrents without a June 18 patch.
-
Delta Force: TiMi Studio Group's free tactical shooter. The DFI Warfare World Championship ran in Wuhan June 17 through June 21 ahead of Season Meltdown on June 30.
-
Tom Clancy's Rainbow Six Siege: Ubisoft's tactical shooter. Operation System Override launched June 2 with the Calypso Casino map and a Ranked 3.0 overhaul.
-
EA SPORTS FC™ 26: Electronic Arts' soccer sim with a 48-team World Cup tournament mode. An 80% Steam discount to $13.99 runs through June 25, timed to the June 11 World Cup kickoff.
-
Stardew Valley: ConcernedApe's farming sim. No June content drop was reported; the title holds a steady player floor ahead of the June 25 Steam Summer Sale.
-
Don't Starve Together: Klei Entertainment's co-op survival game. Cursed Confrontation Part 1 arrived June 11 during Klei Fest 2026 with new boss content and free anniversary skins.
-
VRChat: A social VR and desktop avatar platform. June concurrents near 45,000 on Steam reflect routine world-hopping rather than a patch cycle.
-
Forza Horizon 6: Playground Games' Japan-set racer, released May 18, 2026. VGChartz ranked it second on Steam weekly top sellers for the week ending June 16.
-
Grand Theft Auto V Legacy: Rockstar's original PC GTA V build, renamed after the March 2025 Enhanced release. Mod and FiveM players keep daily peaks above 50,000 without a June 18 patch.

What today's Steam chart reveals
Idle and taskbar games separate June 18 from a normal Steam leaderboard. TBH: Task Bar Hero and Bongo Cat hold two of the top six slots. TBH launched May 27 and already ranks above Dota 2 and PUBG, driven by market-farming curiosity per coverage on June 17.
Timed events explain several mid-chart movers. Destiny 2's June 9 finale patch, Dead by Daylight's free week, Warframe's June 17 expansion, and Rust's June 4 wipe each added a dated trigger within two weeks. Counter-Strike 2 and Dota 2 show no June patch cycle and remain recurring fixtures whose ranks shift with time-of-day concurrency.
