The modern gaming landscape has made room for a wonderful resurgence of retro-style development, with few projects feeling as authentic as Earthion. This new side-scrolling shooter comes from Ancient Corporation, the Japanese studio founded and led by legendary composer Yuzo Koshiro.
His name alone signals a certain commitment to the 16-bit era, and this game is a direct product of that passion. The premise is pure pulp sci-fi. Long after humanity abandoned a depleted Earth for a new home on Mars, a mysterious alien force attacks the planet. You are Azusa Takanashi, an environmental researcher turned vengeful pilot.
From the cockpit of the YK-IIA, a powerful fighter built using captured enemy technology, you represent Earth’s last line of defense. The stage is set for a classic arcade battle, channeling the spirit of the games that defined a generation.
Familiar Skies, Forgiving Fights
At its heart, Earthion presents a gameplay loop immediately recognizable to anyone familiar with the shoot ’em up genre’s golden age. The fundamental experience is a direct descendant of classics like Konami’s Gradius or Irem’s R-Type, focusing on navigating intricate enemy patterns and screen-filling bosses from a horizontal perspective.
The developers show a clear understanding of what makes this format work, occasionally shifting the scrolling direction to vertical for certain sequences, which prevents stagnation and keeps the player’s spatial awareness engaged. The core of your offensive capability lies in the YK-IIA’s weapon systems.
Your primary fire begins as a simple forward-facing shot, but its power grows by collecting green “Solrium” crystals dropped by destroyed enemies. This creates a satisfying feedback loop where aggression is directly rewarded with increased firepower, a staple design choice that encourages continuous engagement over timid avoidance.
The sub-weapon system offers a layer of tactical choice. Unlike the linear upgrade path of the Gradius power-up bar, where players cycle through a set menu of enhancements, Earthion uses a direct pickup system. You can find and equip distinct secondary weapons, such as a spread shot for crowd control or a powerful laser for focused damage on armored targets.
Your ship has a limited number of inventory slots for these weapons, allowing you to stock a small arsenal and switch between them on the fly. This system demands strategic foresight; picking up a new weapon when your slots are full will replace the one you currently have selected, a situation that can be disastrous if you discard a crucial tool just before a boss fight.
Where Earthion diverges most notably from its Hard-as-nails predecessors is in its approach to player survivability. The game eschews the punishing one-hit-kill design that defined many arcade classics. Instead, your ship is protected by a regenerating shield, a design choice that makes the experience far more accessible to players who may not have lightning-fast reflexes.
The shield can absorb several hits before your ship is destroyed, and it will slowly recharge if you can avoid taking damage for a short time. This mechanic lowers the entry barrier significantly, but it does not remove the challenge. A crucial design element is that taking damage depletes not only your shield but also your primary weapon’s power level. This creates a risk of a “death spiral,” where a few mistakes can leave you with a peashooter against a screen full of enemies, making recovery a frantic and difficult process. This system ensures that even with a shield, every hit feels meaningful and every enemy bullet demands respect.
The simple, three-button control scheme is responsive and intuitive, with the dedicated button for firing both weapons at once being a welcome quality-of-life feature that saves players from holding down two buttons during intense firefights. The inclusion of multiple difficulty settings, from a manageable Easy to a punishing Beast mode, allows players to tailor the challenge to their exact skill level.
The Spoils of War
While the moment-to-moment action is the main attraction, Earthion incorporates a simple yet effective progression system that adds a compelling strategic layer across the entire campaign. This system revolves around a specific pickup called the “Adaptation Pod.” If you manage to pilot your ship over one of these pods, which typically appear once per stage, you gain the opportunity to purchase a permanent upgrade at the level’s conclusion.
These are not minor tweaks; they are significant enhancements that shape your capabilities for the rest of the game. You can choose to increase the number of sub-weapon slots, allowing for greater tactical flexibility. You might instead invest in improving your shield’s overall capacity, making your ship more resilient. A third option is to acquire an extra life, a classic upgrade that provides a safety net for difficult sections ahead.
This upgrade path introduces a fascinating element of risk versus reward that is central to strong arcade game design. The Adaptation Pod often appears in a dangerous part of the screen or during a chaotic enemy wave. Securing it might mean forgoing another useful item, like a powerful sub-weapon or a shield-restoring pickup.
This forces the player to make a split-second decision: do you take the immediate, temporary advantage, or do you risk your current life for a permanent, long-term gain? This choice gives each playthrough a unique feel and encourages players to develop different build strategies. One player might focus on creating a glass cannon with a wide array of weapons, while another might build a defensive tank designed to outlast the enemy.
The game’s structure is a throwback to its 16-bit inspirations, consisting of an eight-stage campaign. In a bold commitment to authenticity, Earthion forgoes modern save states and auto-saves in favor of a classic password system. After completing a stage, the game provides you with a code.
Entering this code later allows you to resume your game not from a checkpoint, but from the beginning of the next level with all of your acquired upgrades intact. For younger players, this might seem archaic, but for veterans, it is a nostalgic nod to a time when game progress was a hard-won prize. This design choice reinforces the feeling of playing a genuine relic from the past.
To add value beyond the main story, the game includes a “Challenge Mode” with four distinct scenarios. These are not throwaway extras; they are focused tests of specific skills. Two are score attack trials that challenge your ability to route through a level efficiently while maximizing destruction. The other two are time trials against bosses, demanding perfect pattern recognition and optimal damage output. These modes give skilled players a great reason to continue honing their abilities long after they have seen the credits roll.
A Gorgeous, Hazy Memory
From a visual standpoint, Earthion is a stunning love letter to the 16-bit aesthetic. The artists at Ancient Corporation have demonstrated a deep understanding of what made the top-tier games on the Sega Genesis and Mega Drive look so good.
The pixel art is exceptionally well-crafted, with detailed and imaginative enemy sprites, layered parallax scrolling backgrounds that create a sense of depth, and impressively fluid animations that give the on-screen action a tangible sense of impact.
The PC version is clearly not bound by the original hardware’s limitations, allowing for more sprites on screen and more complex special effects than would have been possible in the 1990s. The result is a game that looks like a pristine, idealized memory of a 16-bit classic. The color palette is intentionally bright and vibrant, a hallmark of many arcade shooters designed to catch the eye.
This commitment to a vibrant aesthetic, however, gives rise to the game’s most significant and frustrating design flaw: a lack of visual clarity. On certain stages, particularly the notoriously busy level 3, the screen becomes a whirlwind of colorful explosions, detailed backgrounds, and enemy ships. The issue is that enemy projectiles often share a similar color profile to the scenery behind them, making them incredibly difficult to discern in the heat of battle.
In a genre that demands precision and readability, having bullets blend into the background is a cardinal sin. This can lead to players taking damage from threats they simply could not see, which feels unfair and undermines the game’s otherwise tight design. This is a common pitfall for visually ambitious shooters, and it stands in contrast to games like certain titles in the Touhou Project series, which manage to fill the screen with projectiles while maintaining remarkable clarity through careful color choice and bullet design.
To the developer’s credit, the PC version of Earthion includes an extensive suite of visual customization options that cater directly to retro gaming purists. These features show a deep appreciation for the way these games were originally experienced. Players can apply a filter that perfectly mimics the screen curvature of an old CRT monitor, warping the flat image into a satisfyingly convex shape.
You can activate scanlines, those faint horizontal lines that were a characteristic of tube televisions, to add another layer of authenticity. There are options to adjust the aspect ratio to the classic 4:3, add custom bezels to the sides of the screen, and even apply filters that simulate different qualities of CRT monitors, from a sharp professional video monitor to a “bad” one with greenish, distorted tones. These options are a fantastic inclusion, allowing players to fine-tune the visual presentation to match their own nostalgic ideal.
An Authentic Echo
The sound design of Earthion is, without exaggeration, a monumental achievement and arguably the game’s single greatest strength. This is entirely thanks to the work of Yuzo Koshiro, whose iconic compositions for games like Streets of Rage have left an indelible mark on the industry. His soundtrack for Earthion is not merely good; it is a pitch-perfect embodiment of the 1990s arcade spirit. The score is packed with high-energy, melodic electronic tracks that drive the on-screen action relentlessly.
Koshiro’s mastery of FM synthesis is on full display, using the distinct, metallic tones that defined an entire generation of game music to create something that feels both nostalgic and timeless. The music is not just background noise; it is an active participant in the experience, its tempo and intensity rising and falling with the flow of battle.
The sound effects are crafted with the same dedication to authenticity. They were designed to replicate the output of the Yamaha YM2612 sound chip, the component responsible for the Sega Genesis’s signature sound. Every laser blast, explosion, and power-up chime sounds exactly as it should, completing the immersive retro experience.
This meticulous attention to sound makes the game a joy to listen to, but players on PC should be aware of a potential technical hiccup that could sour the experience. Several reports have indicated that the game has compatibility issues with certain controllers, with the Xbox Series controller being mentioned specifically. The problems range from unresponsive or missed inputs to strange, random disconnections during gameplay.
In a precision-based genre like a shmup, where a single, instantaneous dodge can be the difference between survival and failure, unreliable controls are simply unacceptable. A missed input is not an inconvenience; it is a guaranteed loss of a life or the end of a run. While these issues may not affect all players, and other controllers have been reported to work flawlessly, it is a significant caveat that potential buyers should be aware of before diving in.
