Luna Abyss Review

Fast movement, heavy pressure, and constant survival turn Luna Abyss into one of the more unusual sci-fi shooters recently.

Luna Abyss feels like the result of someone looking at classic bullet hell arcade games and asking what would happen if that style of chaos was pushed into a first-person shooter. Instead of staying close to the usual formula of modern FPS games where you slowly clear rooms from cover, the game builds itself around movement, survival, and constant pressure.

You are not hiding behind walls waiting for enemies to peek out. You are sliding, strafing, dashing, and squeezing through impossible spaces while entire rooms try to overwhelm you. The game constantly forces you to read the flow of each encounter in real time, because attacks rarely come one at a time and instead stack in overlapping waves.

Developer Bonsai Collective is clearly aiming for something different here. The game borrows ideas from old-school arcade shooters like Ikaruga while mixing them with modern movement shooters and atmospheric sci-fi storytelling. From the start of Luna Abyss, it is obvious that realism or military tactics are not the target. 

Luna Abyss already has a strong identity, even in its current state.

A lot of sci-fi shooters use the same old tropes of futuristic guns, dark hallways, and mysterious technology, but this game plays with those tropes in new ways. It’s not about power fantasy combat where you dominate everything around you. Instead, you are trapped within a dangerous place that keeps pushing back at you. 

You play as a prisoner named Fox, or Fess in different previews, who wakes up inside a giant structure buried beneath a mimic moon. The world around you is instantly wrong. You emerge from an open coffin with little understanding of where you are or what happened before you arrived.

The setting itself does a lot of the storytelling. Sorrow’s Canyon, one of the early areas shown, looks like a prison colony built from grimy metal halls, scaffolding, pipes, stone floors, and strange organic growths spreading across the environment. The architecture mixes industrial machinery with gothic horror in a way that feels closer to a nightmare than a functioning facility.

Some areas resemble giant machine cities filled with black stone, neon floodlights, and twisting mechanical structures. Everywhere you go, it feels abandoned, damaged, or corrupted, as if the entire place has been left to decay for so long that even the technology has started to rot, with broken pathways, unstable structures, and strange organic growths.

The game introduces a few characters that help add personality to the world but don’t fully explain it. All along the journey, you hear a guiding voice, Aylin, who sounds strangely casual considering the horrors around you. While most of the people trapped inside Luna sound defeated or broken, she sounds almost amused at times. 

Then there’s the Waif, a mysterious figure who talks in riddles and cryptic statements that only make the setting feel more unsettling. Luna Abyss is more interested in creating mystery and atmosphere than giving up direct answers, and that’s particularly effective for keeping tension as you go deeper into the abyss.

At its heart, Luna Abyss is a first-person shooter, but it plays very differently from most games in the genre. You still get through levels, collect weapons, kill enemies, and explore dangerous areas, but the game is constantly pushing you to keep moving. It's usually a mistake to stand still too long, because enemy attacks quickly fill entire arenas with bullets, lasers, and explosive projectiles.

Movement is a big part of the experience.

You spend a lot of time strafing around enemies, sliding between attacks, jumping across gaps, and using vertical spaces to stay alive. In later sections, you will learn skills like double jumps and air dashes that make your movement much faster and fluid. Some stages have floating platforms and open spaces that encourage you to push forward boldly.

The aiming system is one of the more unique mechanics. Instead of demanding perfect precision, Luna Abyss uses an auto-lock feature that targets enemies closest to your crosshair. At first, that might sound like it removes skill from the combat, but the game quickly proves otherwise.

Because aiming becomes easier, your attention shifts almost entirely toward movement and survival. You are no longer worried about lining up perfect shots while dodging projectiles. Instead, you concentrate on positioning, timing, and reading the enemy’s attack before the room becomes too dangerous to move around.

Weapons also play a major role in how encounters play out. You find a standard firearm early on with an overheating mechanic instead of traditional ammo limits. As the game progresses, new weapons add more depth to combat. A shotgun is particularly effective for breaking some enemy shields, while a long-range rifle does heavy damage but overheats fast.

As you progress, the game keeps adding mechanics. Some parts introduce environmental movement tools, like boost gates that send you careening through levels if you dash through them. Occasionally, you get to control strange floating creatures, giving you the ability to see areas from all sorts of viewpoints. 

There's a sequence where you control a giant monster with a minigun that can shred enemies with ease. These mechanics stave off repetitive gameplay by constantly introducing new ideas along with combat. It also helps break up the pacing, so each section feels a little different from the last.

The game's structure also balances action with exploration and platforming.

One minute you’re in a frantic arena with bullets flying; the next, you’re exploring strange architecture or dodging environmental hazards. That pacing prevents Luna Abyss from becoming a non-stop shooting gallery. The quieter moments allow the world to breathe before you are thrown back into another intense fight.

Combat in Luna Abyss is kind of a hybrid of a movement shooter and a traditional bullet hell game. Enemies attack in patterns rather than in realistic firefights. Floating drones chase you around arenas, eyeball creatures fire giant lasers from elevated positions, and explosive enemies force you to keep moving before they corner you.

Boss fights enhance these mechanics. One of the big fights shown in the previews features a giant floating eyeball that stays at the center of the arena, flooding the room with waves of bullets and lasers. The safe spaces are always moving because the attacks are layered and you have to be aware of everything around you. 

In some phases, the boss becomes invulnerable, and you need to destroy power sources or survive waves of enemies before you can damage them again. These encounters feel more like arcade shooters or games like Returnal rather than traditional FPS boss battles. Hence, this makes the gaming experience more enjoyable.

What Luna Abyss does best is how well its combat mechanics mesh with its atmosphere. The great pressure of enemy attacks supports the idea that you are in a dangerous place, struggling to survive impossible odds. When the game throws in extra movement options and more challenging enemy combinations, the combat gets a lot more interesting. 

The biggest concern is readability. Some fights fill the screen with bullets, effects, lasers, and enemy attacks so quickly that things risk becoming visually overwhelming. If enemy patterns become too chaotic later in the game, frustration could replace excitement. Still, the demos suggest the developers understand that balance fairly well so far.

Luna Abyss does not appear to focus heavily on traditional XP grinding or RPG progression systems.

Progression comes from unlocking new weapons, acquiring movement abilities, and understanding how different enemies behave. There is a feeling that the game is challenging due to the players' skill and adaptability rather than leveling up stats. That fits the overall design, because the satisfaction comes from mastering movement and surviving increasingly difficult encounters.

Luna Abyss has a very specific visual style. Nearly every environment utilizes dark black, red, and white color schemes, neon lighting, and industrial textures. The world is always cold, mechanical, and oppressive. Some are like abandoned prison complexes; others are like giant cities of machines buried underground.

Effective use of scale and verticality also helps the game make locations feel more expansive. The floating platforms, giant structures, distant landscapes, and endless industrial machinery all help sell the idea that Luna is massive and ancient. Even the quieter exploration segments feel tense, with the environments themselves appearing hostile.

Sound design is important in maintaining that atmosphere. Combat is loud and chaotic, with projectiles, lasers, explosions, and weapon effects piling on top of one another. Throughout the lulls, strange ambient sounds and disturbing dialogue maintain the tension. Fights are fiercer when they erupt due to the contrast between silence and the deafening din of battle.

Luna Abyss is already distinct from most modern sci-fi shooters by fully committing to its movement-heavy bullet hell identity. 

Rather than using arcade mechanics as a gimmick, the game bases its entire combat system on surviving overwhelming attacks in motion. The auto-lock aiming system may seem simple at first glance, but it actually helps to shift focus to positioning, movement, and awareness, which is where the real challenge is.

The atmosphere of the game helps too. Luna Abyss has its own identity that sets it apart from more generic shooters with its mysterious world, strange characters, oppressive environments, and constant sense of danger. It never feels like a standard military FPS with a sci-fi skin layered on top.

There are still things the full release needs to prove. Enemy readability, long-term combat variety, and storytelling depth will matter a lot over the course of a complete game. But based on the footage and demos shown so far, Luna Abyss looks like a creative and confident attempt to merge first-person shooting with arcade-style survival mechanics.
