An enthralling Genesis shoot-em-up, Earthion blends classic 16-bit charm with modern gameplay innovations.
Blast Off Into Earthion’s Retro-Futuristic World
If you’re a fan of retro shoot-em-ups, Earthion is bound to ignite your excitement. As soon as you strap in and pilot the YK-IIA spaceship, you’re whisked into a vibrant universe where aliens threaten Earth, and it’s up to our hero scientist Azusa Takanashi to save the day. This Genesis title from Ancient Corp is a loving homage to classics like Thunder Force III and Whip Rush while staking out its own unique territory.
The team behind this gem includes Makoto Wada, a talented artist and programmer, and the legendary composer Yuzo Koshiro – whose work on Ys and Streets of Rage speaks volumes. Their combined expertise shines through every pixel and note.
Classic Genesis Feel with a Modern Twist
The essence of Earthion is pure Genesis shoot-em-up magic. The controls have that tight, responsive feel you crave, but the game also introduces fresh mechanics that make it stand out. One such innovation is the regenerating shield system—a feature that was pretty rare for 16-bit shooters. Your shield can take two hits before you’re vulnerable, but if you dodge damage for a few seconds, it regenerates back to full strength.
This shield mechanic balances the game perfectly. Enemy fire is dense and relentless, pushing you to stay sharp. Quick reflexes are a must to dodge the barrage, but you also need a solid offense to thin out foes before they overwhelm you. The programmer’s talent really shows here—no flickering or slowdowns plague the action, despite the heavy on-screen chaos. That’s a rarity for the era and a pleasure to experience.
Loadout Flexibility Keeps Gameplay Fresh
Weaponry in Earthion is as flexible as it is fun. You always have a rapid-fire primary weapon, but the real excitement comes from the two subweapon slots you can fill throughout stages. These subweapons power up by collecting green gems, but beware—a hit will drain their strength, and lose them if it hits zero.
The game limits which subweapons appear in each level, but the diversity is impressive. You’ll find:
- Detonator: Bombs lobbed upward and downward simultaneously.
- V-Fire: Dual lasers firing above and beneath your ship.
- Pyro Cannon: A fiery flamethrower for close-range havoc.
- Hyper Missiles: Explosive shots that pack a punch.
- Targeting Cursor Weapon: An unusual and strategic bomb launcher that detonates where you aim.
Each weapon invites a different playstyle, letting you strategize how to tackle waves of enemies and bosses.
Upgrade Pods and Password System Empower Your Journey
Earthion introduces a special twist with adaptation pods found in every stage. These take up a subweapon slot but don’t do anything on their own. Reach the end of a stage with one intact, and you unlock a choice of upgrades. These might permanently boost your shield, expand your power gauge, increase subweapon levels, or grant an extra life.
What’s more, after a game over, you receive a password that lets you restart with all your upgrades intact. This system means the game is approachable for newcomers but can still challenge the hardcore player who opts to forego the boost and enjoy a pure arcade experience. With four difficulty levels and a smart password feature, Earthion balances accessibility and depth beautifully.
Stages Packed With Visual Flair and Varied Challenges
The level design in Earthion is a masterclass in blending the familiar with the fresh. The first stage kicks off in Earth’s orbit, featuring an elaborate boss fight where satellites orbit an enemy ship with early 3D effects. Luckily, these satellites won’t harm you—just dodge their targeting cursor and enemy fire.
The second stage’s cloudy skies flaunt gorgeous parallax scrolling, followed by a haunting ruined city in the third level, featuring a crushed Statue of Liberty—a classic post-apocalyptic sight for retro fans.
Stage four opens with a thrilling chase through tight tunnels, reminiscent of Life Force, where you clean up biological goo. The fifth stage moves underground into a fiery cavern, battling a massive MECHA with fierce claws and flame pillars.
The final three stages form a long, intense assault on the alien HQ. You start by circling its exterior, then zoom inside for a Gradius-style base invasion, and finish with a three-part showdown in outer space. Each level entrances with slick animations of the Earthion ship smoothly entering or exiting the screen, showcasing the game’s hefty 60-megabit ROM size—much larger than typical ’90s Genesis shooters.
Yuzo Koshiro’s Stellar Soundtrack Rockets the Experience
No Ancient Corp game would be complete without Yuzo Koshiro’s musical genius. The soundtrack is an exhilarating blend of orchestral hits reminiscent of Konami’s style and complex compositions that exceed typical 16-bit soundtracks.
The best tracks come near the end: the penultimate stage boasts a Gradius-inspired anthem, while the final battle rocks with a heavy metal tune that rivals classics like MUSHA and Thunder Force IV in showcasing the Genesis sound chip’s fury.
Bonus trivia: the OST includes a track called “Space Travel 2025,” inspired by an unused composition from ActRaiser made nearly 35 years earlier—talk about bridging gaming generations!
Multiple Versions, a Modern Launch, and Retro Faithfulness
Though made for the Genesis, Earthion debuted first as an emulated release on computers and modern consoles thanks to BitWave, known for reissuing classic arcade titles. It offers various display tweaks, including color adjustments that mimic CRT monitors on HD screens.
Unlike typical emulated games, there’s no save state or rewind functionality—because this is a new creation, not a retro port, and the developers wanted to preserve challenge integrity. The release package also includes prototypes showing the game’s evolution, like an early build where you pilot a mecha instead of a spaceship.
The original bullet design featured spinning triangles that were tricky to see, but a later update swapped them for round bullets—definitely easier on the eyes.
Earthion also made its way to the exA-Arcadia arcade platform, featuring alternate soundtrack versions and a revamped scoring and hyper system to suit the arcade scene. Unfortunately, that mode is exclusive to the arcade cabinet, which is a bit frustrating since it could have been a cool optional setting in the home release.
Why Earthion Stands Out Among Genesis Shooters
Comparing Earthion to ’90s Genesis shoot-em-ups might seem unfair—after all, it benefits from three decades of design evolution and isn’t hampered by the compromises of commercial releases. But more importantly, it’s the heartfelt work of two brilliant creators pouring passion into a game that feels both nostalgic and fresh.
Whether you’re a die-hard retro shooter fan or a newcomer curious about the Genesis library, Earthion delivers a thrilling space blast that’s hard to forget.
“The action doesn’t flicker and rarely slows down, alleviating a regular problem from the era.”
