Steam may have just thrown its weight behind bullet heaven, but last week’s standout game was a one-of-a-kind bullet hell FPS

Steam has officially recognized the “bullet heaven” genre with a new store tag, categorizing games similar to Vampire Survivors. However, the standout release last week wasn’t a bullet heaven game, but rather Luna Abyss, a unique bullet hell FPS.

Luna Abyss transforms the bullet hell genre into a 3D first-person experience, following the model established by Returnal. Rather than traditional 2D dodging mechanics, Luna Abyss presents hundreds of brightly colored projectiles in three-dimensional space that players must navigate.

This represents a notable distinction in gaming genres. Bullet heaven games emphasize survival-focused, casual gameplay loops like Vampire Survivors, while Luna Abyss maintains the skill-demanding, pattern-intensive design of traditional bullet hell shooters, adapted to modern 3D graphics and first-person perspective.

The timing highlights an interesting contrast: as Steam formalizes one emerging genre category with an official tag, developers continue pushing genre boundaries with innovative approaches like Luna Abyss’s 3D interpretation of bullet hell gameplay.
