The peak number of players reached 117,336. The project was released on September 19, 2025, by Vedinad studio, essentially a pseudonym of a single developer, Danidev, in reverse. The author worked on the game for about a year, explaining in a YouTube video in February 2025 that he had been working on Megabonk for "already 4 months" at that point.
The developer noted that he was inspired by Vampire Survivor — a 2D game with similar mechanics. He decided to create an analogue, but in 3D, adding movement dynamics. As a result, Megabonk turned into a mix of Vampire Survivor, Risk of Rain, DmD, Halls of Torment, and other roguelike projects that the author enjoys.
