The co-developers behind the hit indie co-op game PEAK recently made headlines by addressing a controversial Roblox clone. Aggro Crab, one of the creators, took to X on August 4, 2025, to express their disapproval of the clone, urging fans to pirate their game rather than playing what they termed a “microtransaction-riddled Roblox slop ripoff.” Their partner, Landfall Games, echoed this sentiment with a simple “Cosigned.”
The clone, called Cliff, has made waves with its similarity to PEAK in character design, game mechanics, and even promotional materials. The developers of Cliff admitted their game was “inspired” by both PEAK and another game, Mountain Climbing. However, the similarities go beyond mere inspiration. Cliff mirrors PEAK’s gameplay, including third-person hubs and first-person climbing zones, but it introduces aggressive microtransactions like a $2 pickaxe and a $1.29 golden apple.
Despite these practices, Cliff has achieved significant traction on Roblox, with over 4.8 million visits and 7,000 active players. This issue isn’t isolated to Cliff; Roblox is rife with clones of popular games, many targeting younger players with aggressive monetization.
There is a positive twist to this story, though. In response to the outcry from Aggro Crab, PewStudio, the developers of Cliff, announced on their Discord server that they would shut down the game at PEAK’s request. Nonetheless, many PEAK-inspired clones persist, underscoring the popularity of this emerging sub-genre.
PEAK itself is a runaway success, launching on the Steam Store on June 16, 2025, and selling 5 million copies within its first month. By July 6, it achieved a peak of 114,492 concurrent players and maintains a steady daily average of 60,000 to 70,000 players. With a 93.05% user score and over 77,713 positive reviews, PEAK holds a “Very Positive” status on Steam, cementing its place as a favorite among gamers.
