Luna Abyss Review: Bullet Hell Brilliance Trapped in a Flawed Cosmic Descent

Released on May 21, 2026, by UK studio Kwalee Labs (with development roots in Bonsai Collective), Luna Abyss is a bold first-person action-adventure that throws players into a derelict megastructure beneath a mimic moon. You play as Fawkes, a prisoner forced to descend into this haunting abyss filled with cosmic horrors, surreal architecture, and relentless enemy waves. Blending high-mobility FPS gunplay with bullet hell dodging, fluid platforming, and a cryptic sci-fi narrative, it aims to carve its own identity in a crowded genre. It mostly succeeds — delivering exhilarating moments that echo Doom Eternal and Returnal — but stumbles with readability issues and repetition that prevent it from reaching masterpiece status.

At its core, Luna Abyss is a movement shooter. You dash, double-jump, and wall-run through crumbling industrial ruins and dreamlike voids while fending off swarms of biomechanical enemies. Combat revolves around heat-based weapons rather than traditional ammo — encouraging constant cycling between firearms to avoid overheating. This creates a rhythmic flow: shoot, dodge dense projectile patterns, reposition with graceful traversal, and execute weakened foes for energy pickups in a Doom Eternal-style glory kill system.

The bullet hell elements shine brightest in boss fights and arena encounters. Screen-filling patterns demand precision and spatial awareness. One memorable mid-game boss forces you to weave through rotating laser grids while platforming across collapsing structures — a thrilling hybrid of shmup intensity and FPS mobility. Early levels feel a bit sluggish, but once momentum builds (around the 2-3 hour mark), the game hits a glorious stride.

Platforming is another highlight. Fluid movement mechanics make traversal satisfying, whether you’re leaping across chasms or scaling towering ruins. However, some sections suffer from imprecise collision detection or frustrating camera angles, leading to cheap deaths that break the flow.

Luna Abyss excels in creating an oppressive, surreal atmosphere. The derelict megastructure feels alive with gothic sci-fi horror — think BioShock meets Yoko Taro weirdness. Red-lit corridors, floating debris, and grotesque organic machinery paint a haunting picture of a failed colonial experiment. Environmental storytelling through logs, visions, and architecture reveals a compelling mystery about identity, sacrifice, and the cost of exploration.

The visual style is striking, especially on higher-end hardware. Surreal lighting, particle effects during bullet hell sequences, and a consistent red-black palette create memorable tableaus. That said, performance can dip during chaotic fights, and some textures look muddy on console — a common complaint in reviews.

flow

You descend as Fawkes, uncovering the moon’s dark secrets through fragmented memories and enigmatic NPCs. The narrative starts slow but builds to surprising revelations with strong themes of isolation and humanity. It won’t win awards for depth, but it’s more engaging than many shooters in the genre. Voice acting is serviceable, though some deliveries feel flat.

fin

Luna Abyss is an ambitious indie effort that captures the chaotic joy of dodging bullet patterns while sprinting through stunning sci-fi ruins. It channels Doom Eternal’s aggression and Returnal’s intensity but never quite masters either fully. For fans of stylish, story-driven shooters willing to overlook some rough edges, it’s a rewarding descent into the unknown.

Score: 7.8/10 — A stylish, chaotic bullet hell shooter that almost hits its targets. Worth playing, especially on Game Pass, but not without its flaws.
