Valve’s Deadlock Surpasses Team Fortress 2 Steam Player Peak
Valve Corporation’s unreleased multiplayer game Deadlock reached 262,145 concurrent players on Steam on October 9, 2026, passing the all-time concurrent player peak of Team Fortress 2, which stands at 253,997, according to Steam player data tracked by SteamDB and reported by outlets including ghacks.net and PC Gamer.
The Tech TL;DR:
- Deadlock hit an all-time peak of 262,145 concurrent players on Steam on October 9, 2026, eclipsing Team Fortress 2’s historical Steam peak of 253,997 set on July 13, 2023.
- The player surge coincided with the release of the “City Never Sleeps” update, which overhauled the Cursed Apple map and introduced new heroes, including the chess-themed character Solomon.
- Despite reaching these concurrency numbers, Deadlock remains in an invite-only closed playtest on PC via Steam and has no official public release date announced by Valve.
Map Overhauls and the Arrival of Solomon in the City Never Sleeps Update
The record-breaking concurrent player milestone arrived alongside Valve’s rollout of Solomon, one of six new heroes in the MOBA title’s “City Never Sleeps” update. PC Gamer noted that Solomon’s release on October 9 marked the third of six hero deployments arriving at a rate of two per week, following the Rat King on October 2 and Baba on October 6. The update also includes upcoming additions Deadman Danny, Nurse Harrow, and Violet.
Under the hood of the application, the update completely rebuilt the core map, known as the Cursed Apple, restructuring its layouts around an occult-themed 1950s New York setting. Broadway now serves as a neon-lit central district featuring a miniature version of 1950s Times Square, while Greenwich has transformed into a Central Park variant with an arboreal garden and university. York’s former walker arenas were repurposed into a stock exchange and factory grounds, accompanied by themed lane districts featuring specialized creeps and architectural assets.

Comparing Valve’s Concurrent Player Milestones Across SteamDB Metrics
While Deadlock’s 262,145 concurrent users surpassed Team Fortress 2’s peak of 253,997—a margin of 8,148 players—PC Gamer pointed out a crucial contextual caveat regarding historical numbers. Team Fortress 2’s record, set on July 13, 2023, reflects only its Steam client metrics and excludes historical console players from the Xbox 360 and PlayStation 3 versions released in The Orange Box. PC Gamer highlighted that Dota 2 and Counter-Strike 2 operate in substantially larger tiers within Valve's catalog, noting that Dota 2's all-time peak reached 1,295,114 on March 6, 2016, and Counter-Strike 2 peaked at 1,862,531 on April 12, 2025.
| Game Title | Development Status | All-Time Steam Peak | Peak Date |
|---|---|---|---|
| Counter-Strike 2 | Released, free-to-play | 1,862,531 | April 12, 2025 |
| Dota 2 | Released, free-to-play | 1,295,114 | March 6, 2016 |
| Deadlock | Invite-only closed test | 262,145 | October 9, 2026 |
| Team Fortress 2 | Released, free-to-play | 253,997 | July 13, 2023 |
Access Protocols and the Ongoing Closed Playtest Phase
Deadlock continues to operate as an invite-only closed test on PC through the Steam platform without a finalized retail price or public release schedule. Acquiring access requires receiving an invitation directly through Steam from an existing participant or obtaining invite links shared within community Discord servers. The ongoing playtest format has allowed the title to evolve continuously through developer iteration since initial gameplay leaks surfaced approximately two years ago, transitioning through aesthetic shifts from an early cyberpunk concept to the current noir architecture.

// Example initialization check for Steamworks API client invite state
SteamAPICall_t hSteamAPICall = SteamFriends()->JoinClanChatRoom(k_uSteamIDLobby);
if (hSteamAPICall == knumAPICallInvalid) {
// Handle closed playtest restriction or invalid invite token
}
The content deployed within the “City Never Sleeps” update incorporates major structural work leading toward the later stages of production polishing. Valve has not issued a formal press release or timeline regarding when the application will transition out of its invite-only testing phase.
