Earth Atlantis Abyss Brings Roguelike Submarine Combat to Steam in Q1 2027

Earth Atlantis Abyss has been announced for PC via Steam, with Pixel Perfex, Eccentrix Studios and publisher Rising Tide Publishing planning a launch in Q1 2027. The newly revealed project returns to the submerged setting of the Earth Atlantis series, but reframes the action around roguelike runs, a configurable submarine, scarce illumination and a mystery beneath the waves.

At its core, Earth Atlantis Abyss is a shoot 'em up set in a drowned world. Players take command of a submarine and descend through a seven-layer abyss where visibility declines as the depth increases. That progression is not simply an atmospheric backdrop: the vessel's spotlight and its available light are designed as key survival considerations. Going deeper means facing a more hostile environment while attempting to uncover the fate of the protagonist's missing grandfather.

The game is built around a blend of bullet-hell encounters and ship-management decisions. Instead of treating upgrades as straightforward pickups, Earth Atlantis Abyss asks players to arrange equipment inside a limited onboard grid. Weapons, engines, drones and hull components all take up room, creating a packing-puzzle layer that can reshape a run as much as the player's ability to dodge incoming fire.

A new descent into the Earth Atlantis world

Earth Atlantis Abyss stars Pypher, a 17-year-old captain who sets out in her grandfather's aging submarine. Her goal is to investigate his disappearance. Three years before Pypher begins her journey, her grandfather descended into the same area and did not return. The narrative develops as she travels down through the abyss, with each layer revealing further pieces of the story.

The premise gives the game a personal thread amid its otherwise mechanical focus on fighting, navigation and scavenging. Rather than sending a nameless submarine into an abstract sequence of enemy waves, the descent has a specific motivation. Pypher is following an unfinished route in a vessel tied directly to the person she is trying to find.

That setup also fits the series' flooded setting. Earth Atlantis has established a world in which the sea has overtaken much of civilization, and Abyss leans further into the unnerving implications of exploring what remains below. The emphasis here is on darkness, pressure and the limited reach of a spotlight, giving the underwater setting a gameplay role beyond visual flavor.

Light is part of the loadout

One of the most distinctive systems described for Earth Atlantis Abyss is its treatment of light. The seven layers become darker as Pypher descends, and light is a resource that must be rationed. The submarine's spotlight determines how much of the surrounding danger, terrain and space can be seen.

That means the player's view is not necessarily a fixed advantage. A powerful lighting setup could improve awareness, but the game's broader resource pressures suggest that every useful function has to justify its place aboard the sub. In a shoot 'em up, being able to read projectile patterns and enemy movement is essential. Restricting visibility introduces another source of tension, especially when the game's bosses are designed around the bullet-hell identity associated with the series.

The concept has the potential to make preparation as important as reflexes. A run may hinge on whether a player commits enough space and resources to illumination, opts for more offense, or attempts to strike a balance that keeps the ship capable without leaving Pypher exposed in the dark. Earth Atlantis Abyss is presenting the descent as a journey into unknown territory in both story and systems terms.

Build a submarine one module at a time

Between combat sequences, the game shifts toward an inventory-management puzzle. Players will place submarine parts within a small internal grid, with every piece competing for limited room. The available equipment includes weapons, engines, drones and hull modules, allowing builds to alter both the ship's fighting profile and its underlying capabilities.

Placement is only part of the process. Components can be merged and fused to improve them or create hybrid results. One highlighted example involves a Dwarf Star obtained from a boss, which can be incorporated into this crafting and upgrade process. The system is intended to ensure that submarines develop differently from one run to the next rather than following an identical upgrade route every time.

As a roguelike, Earth Atlantis Abyss is therefore aiming for improvisation. Players will have to make choices based on the components they find, the grid configuration they can support and the challenges waiting below. A build that prioritizes drones might play very differently from one built around engine performance or an arrangement of high-powered weapons.

There is another limitation to consider: heat and power. Managing both is necessary to stop weapons from jamming. This adds a practical cost to loading the submarine with aggressive gear. A collection of powerful modules may not be useful if the ship cannot supply them reliably or if overheating turns a crucial firing system into a liability in the middle of a boss battle.

The result is a design where an upgrade is not automatically an improvement. Players need to account for size, positioning, compatibility, power demands and heat output. Those restrictions can make the decision-making more meaningful, especially within a run-based format where the ideal part may not appear and adapting to imperfect options is part of the challenge.

Seven layers, eight bosses and bullet-hell pressure

The abyss contains seven layers and eight bosses. Boss encounters will use bullet-hell combat, placing a heavy emphasis on navigating patterns while maintaining an effective offense. The extra boss beyond the number of layers suggests that the journey will not simply follow a one-layer, one-boss structure, though further details on how the fights are distributed have not been outlined.

Bullet-hell design is a natural match for the submarine theme when combined with the game's lighting mechanic. The player is not only weaving through large volumes of enemy fire but doing so in a world where darkness can obscure what lies beyond the spotlight's reach. Careful movement, a clear sense of positioning and a build that can keep firing without overheating will all matter when the screen becomes crowded.

The boss rewards may also feed directly into the roguelike build loop. The mention of a Dwarf Star taken from a boss indicates that major victories can supply unusual components for fusion or hybrid construction. This creates a useful connection between combat performance and the next stage of ship development: succeeding against a dangerous enemy can fundamentally change the options available for the rest of the descent.

Because no two runs are intended to create the same submarine, repeat attempts should not be solely about learning attack patterns. They will also involve discovering how different modules interact and how far a particular arrangement can be pushed before power, heat or grid capacity demands a change of plan.

Local and online co-op confirmed

Earth Atlantis Abyss will support cooperative play in two forms: local shared-screen co-op and online co-op. The announcement does not specify how duties will be divided between players, but the inclusion of both options gives players a chance to tackle the abyss alongside another captain whether they are playing in the same room or at a distance.

Co-op is especially interesting for a game built around tight combat and equipment management. Extra players can potentially make chaotic bullet patterns easier to survive through coordination, while the limited visibility and changing builds may require a more deliberate approach than simply overwhelming enemies with more firepower. The game's full details on progression and shared decision-making are still to come, but the confirmed modes provide flexibility for both solo roguelike fans and teams looking for a demanding underwater shooter.

Pixel art with a deep-sea focus

Visually, Earth Atlantis Abyss emphasizes detailed pixel art and a dark deep-sea mood. That approach complements its core themes: an old submarine, lost expeditions, dwindling light and a world that becomes less familiar with every layer. Pixel art can sharply define silhouettes and projectile patterns, an important quality in a shoot 'em up, while still leaving room for the murk and mystery needed for the abyssal setting.

The announcement positions Earth Atlantis Abyss as an evolution of the series' submerged action rather than a conventional sequel focused only on arcade shooting. Its combination of roguelike variety, grid-based submarine construction, resource management and story-driven descent gives the project several systems to balance. For players, the appeal may be in mastering all of them at once: building a vessel that fits the available space, keeping it powered and cool, illuminating the way forward, and surviving what waits in the darkness.

Earth Atlantis Abyss is currently planned for PC on Steam in Q1 2027. More details on the seven-layer expedition, the eight bosses and Pypher's search for her grandfather will be worth watching as the game moves toward release.
