Vampire Survivors sparked a wave of imitators, but the genre lacked an official name. Developers and players called it everything from "bullet heaven" to "reverse bullet hell" to "survival roguelike," creating confusion across Steam's storefront and gaming discourse.
Valve stepped in and established a standardized category. Steam now recognizes this specific subgenre with official tagging, giving players a consistent way to find games like Vampire Survivors, 20 Minutes Till Dawn, and Halls of Torment.

The gameplay feels chaotic yet manageable, accessible yet demanding.
