The indie gaming scene on Steam has a new star: Megabonk, an action-roguelike developed by the solo developer vedinad. After its release on September 18th, the game became a massive hit. In fact, it achieved the remarkable milestone of selling over one million copies in just its first two weeks.
Megabonk is best described as an evolution of the popular Vampire Survivors format. It’s a title where players must fight off endless, massive waves of enemy attacks. Also, the game’s popularity has been steadily climbing since its release, culminating in significant concurrent player numbers.
According to data from SteamDB, the game’s peak online player count exceeded 88,500 users in the late hours of October 2nd to early October 3rd. This success places Megabonk in the top 25 most popular new releases of 2025 on Steam, managing to outperform other high-profile new titles in terms of simultaneous users, including games like inZOI, Sid Meier’s Civilization VII, and Dynasty Warriors: Origins.
The game’s reception from the player community has been overwhelmingly positive. As of the time of reporting, Megabonk holds a “Very Positive” rating on Steam, based on nearly 15,000 user reviews, with 94% of them being favorable. This strong critical and commercial performance solidifies Megabonk as one of the surprise success stories of the year for independent game developers.
