PEAK Player Count Against Other Co-Op Titles
The same Valve snapshot places PEAK beside the games it is most often compared with. R.E.P.O. sat three places above it at 20,783.
Every bar below is a concurrent Steam player count from that single chart reading, so the comparison holds at one moment rather than across a month. Readers tracking the same metric elsewhere can check how Helldivers 2 player numbers moved over the same period.

PEAK Monthly Player Count Since Launch
PEAK average players fell through the first half of 2026, bottoming at 13,181.72 in June. The Final Ascent update on August 11, 2026 reversed that inside a week.
Average players measures the mean concurrent count across the month. Peak players is the single highest concurrent reading in that month. The two are not interchangeable, and Steam Charts publishes them as separate columns.
| Month | Average players | Peak players |
|---|---|---|
| June 2025 | 62,045.26 | 113,290 |
| July 2025 | 52,400.99 | 113,552 |
| August 2025 | 64,798.07 | 169,910 |
| September 2025 | 28,271.29 | 71,540 |
| October 2025 | 17,332.23 | 43,716 |
| November 2025 | 28,743.92 | 73,157 |
| December 2025 | 21,577.22 | 44,872 |
| January 2026 | 24,185.96 | 48,692 |
| February 2026 | 16,093.99 | 34,810 |

| June 2026 | 13,181.72 | 25,148 |
| July 2026 | 13,446.63 | 24,784 |
| August 2026 | 41,948.94 | 122,714 |

Is PEAK Losing Players?
Steam Charts put August 2026 average players up 211.97% on July 2026. The three months before that each sat below 19,000.
The same pattern followed the November 2025 Roots update, when average players rose 65.84% on October. Update-driven spikes of this shape also show up in the Lethal Company concurrent player history and in Phasmophobia activity levels.
When Did PEAK Peak?
August 2025 holds PEAK’s highest monthly reading. Steam Charts recorded 169,910 concurrent players that month, the highest in its dataset for the game.
Other trackers publish slightly different all-time figures from their own sampling of Steam’s API: tracker.gg lists 170,645 and Steambase lists 170,759 for August 17, 2025. Valve does not publish an all-time concurrent peak, so no single official number exists.
Alinea Analytics tied the record to a specific Sunday. The firm reported roughly 171,000 concurrent players and over 1.3 million daily active users on August 17, 2025, six days after the Mesa update and a discount from $7.99 to $4.95 both landed on August 11.
PEAK Peak Player Count By Update Month
Each of PEAK’s three major content updates produced a monthly peak well above the months around it.
| Update | Release date | Monthly peak players |
|---|---|---|
| Mesa | August 11, 2025 | 169,910 |
| Roots | November 5, 2025 | 73,157 |
| The Final Ascent | August 11, 2026 | 122,714 |

How Many Copies Has PEAK Sold?
Aggro Crab reported 11 million copies sold in October 2025, the most recent figure either studio has given. The studio has 13 employees.
Copies sold and concurrent players measure different things. One buyer can stop playing entirely, and the 11 million figure says nothing about how many of them logged in this week.
| Milestone | Time from launch | Reported |
|---|---|---|
| 100,000 copies | 24 hours | June 2025 |
| 1 million copies | 6 days | June 22, 2025 |
| 11 million copies | About 4 months | October 2025 |

PEAK Revenue And Development Cost
Alinea Analytics put PEAK at 9.7 million copies and more than $55 million in revenue as of August 17, 2025. These are the firm’s own estimates from Steam data, not figures either studio published.
For June 2025 alone, Alinea reported 3.1 million copies and $17 million in revenue, making PEAK Steam’s best-selling game that month by copies.
Aggro Crab has said development cost under $200,000. The game was built in roughly four months, with the core of it assembled during a month-long game jam in Seoul. That budget sits several orders below a retail release such as Battlefield 6.
| Measure | Figure | Period |
|---|---|---|
| Copies sold | 9.7 million | To August 17, 2025 |
| Revenue | Over $55 million | To August 17, 2025 |
| Daily active users | Over 1.3 million | August 17, 2025 |

What Platforms Is PEAK On?
PEAK runs on Windows through Steam. Valve’s store page lists no Mac or Linux build.
Both studios confirmed at The Final Ascent announcement in August 2026 that PEAK is being ported to other platforms and will support cross-platform play when that happens. No platforms or dates have been named, and the studios ruled out Steam Workshop support for that reason. Games already running that way, such as Sea of Thieves and ARC Raiders, split their player counts across storefronts in a way PEAK currently does not.
The Final Ascent is the last major content update. Aggro Crab and Landfall have said PEAK was never built as a live-service game and that both teams are returning to separate projects, with bug fixes and maintenance continuing.
