Ex-Zodiac

The on-rails space shooter is a dead genre. Not niche — dead. Nintendo hasn’t shipped a proper Star Fox since 2016’s motion-control apology tour, Panzer Dragoon lives on as a remake nobody asked twice about, and the entire design language of forward is mandatory, sideways is strategy has been absorbed into boss-rush segments of other games. Into that vacuum walks Ex-Zodiac, credited to solo-scale developer MNKY, and it does something more interesting than mourn the genre. It plays like the genre never stopped.

You’re Kyuu, a pilot working through the Sanzaru Star System to break the grip of Zodiac, an intergalactic terrorist outfit whose lieutenants each anchor a stage as a set-piece duel. That’s the entire narrative apparatus, and it’s the right amount. This is a game about the twelve seconds between spotting an enemy formation and deciding whether to boost through it or brake and let it come to you.

Market positioning is unambiguous: this is a love letter, and it’s honest about it. Chunky untextured polygons, a disciplined retro palette, an original 16-bit soundtrack built from FM and wavetable synthesis. Player sentiment on Steam has been strongly positive, and the game is consistently described as the Star Fox 64 successor that never officially arrived.

The asterisk is large and it is structural. Ex-Zodiac has been in Early Access for years. The build offers 11 main levels plus 6 bonus levels. The branching routes and hidden areas — the exact features that gave Star Fox 64 its legendary replay value — are still listed as planned for 1.0. This is not a finished argument. It’s a very convincing first draft.

• Six-input flight model: Strafe, boost, brake, and barrel roll, layered over standard rail movement. The barrel roll deflects incoming fire — a defensive verb with real timing cost, not a cosmetic flourish.
• 17 stages across four biome types: Canyons, oceans, orbital stations, and asteroid fields, each terminating in a boss duel with distinct attack patterns and weak points.
• Authentic low-poly presentation: Untextured flat-shaded geometry and a restrained palette that reads as period-accurate rather than filtered-nostalgia-accurate.
• Original FM/wavetable soundtrack: Composed in genuine 16-bit idiom, and repeatedly singled out by players as a standout rather than set dressing.
• Full controller support: Xbox and PS4 pads with remappable inputs, plus keyboard and mouse.
• Broad localization: English, Japanese, Simplified and Traditional Chinese, Latin American Spanish, and Russian.
• Steam platform hooks: 28 achievements, Cloud saves, Family Sharing, and native builds for Windows, macOS, and Linux/SteamOS.

The Gameplay Loop

Rail shooters live or die on one question: does forward motion feel like pressure or like a conveyor belt? Ex-Zodiac gets this right in a way that’s difficult to overstate. The rail moves you, but boost and brake let you negotiate with it — pull ahead of a formation to hit it head-on, or drag behind to let a wall of fire pass and clean up the stragglers. That single pair of inputs converts a fixed path into a tempo instrument.

Strafing handles lateral positioning; barrel rolling handles the shots you couldn’t dodge. The critical design choice is that these overlap. A roll costs you aim recovery, so spamming it as a panic button degrades your damage output. Good play looks like restraint. That’s a real skill curve inside what appears, from the outside, to be a simple game.

Boss Design Is the Main Course

Every stage funnels into a Zodiac member with its own attack patterns and weak points, and this is where the game’s reputation was earned. Player consensus treats the bosses as the highlight, not the levels leading to them, and the structure supports that read: the run-up teaches a movement idiom, the boss demands it be performed under a stricter clock. It’s a tight instructional arc, executed 17 times.

The friction point that surfaces in player feedback is difficulty spikes. Not a difficulty level problem — a pacing problem. Individual encounters occasionally jump the established curve, which is survivable in a game with generous retries but corrosive in a genre built on flow. When the game teaches a pattern for five stages and then hands over one that punishes the read, it briefly stops feeling designed and starts feeling assembled.

Progression, or the Lack of It

Here is the honest structural critique, and it’s the one that matters most. Star Fox 64’s genius was never its stage count — it was the route map. Branching paths meant a second run was a different game, and a third was a different game again. A modest amount of content generated an enormous amount of play.

Ex-Zodiac ships the stages and not the map. Branching routes and hidden areas are 1.0 features. What’s left is a linear campaign of 17 levels, and once they’re cleared, the game’s answer to what now? is thin. There’s no robust score-attack scaffolding, no leaderboard-driven replay structure — something players consistently ask for in reviews. 28 achievements carry more load here than achievements should ever be asked to carry.

The result is a game with a strong minute-to-minute loop and an underdeveloped hour-to-hour one. The moment to moment is easy to love. The reason to return next month is harder to articulate.

The Early Access Problem

Early Access is a contract, and the currency of that contract is update cadence. Players in the review corpus aren’t complaining about Ex-Zodiac’s quality; they’re complaining about its clock. Several years in, with the defining structural features still pending, the sentiment has shifted from excited to patient, and patience is a depreciating asset. Positive sentiment is a vote of confidence in what exists. It should not be read as a vote of confidence in the roadmap.

If buying today, buy the current build on its own terms. If 1.0 lands with branching routes intact, that’s a bonus. Plan around it and disappointment is a reasonable outcome.

The art direction is the most confident thing here. Untextured flat-shaded polygons and a restrained palette — that restraint is the whole trick. Most retro throwbacks over-saturate and over-detail, chasing the memory of how old games looked rather than how they actually looked. Ex-Zodiac renders the real thing: readable silhouettes, hard color separation, geometry legible at speed.

That legibility pays a genuine gameplay dividend. Enemy projectiles pop against flat backgrounds with zero ambiguity, so deaths read as player error rather than the renderer’s. There’s a cost, though, and it’s worth naming: untextured surfaces are poor speed cues. Canyon walls without surface detail rob peripheral vision of the optical flow that sells velocity. In the ocean and asteroid stages, where the environment is inherently sparse, the sensation of speed leans almost entirely on the audio and the FOV rather than the visuals.

The soundtrack does heavy lifting to compensate. FM and wavetable synthesis, composed rather than pastiched, and it’s the element players cite most often after the controls. It’s period-correct without being a museum piece.

Technically, a 2D-and-low-poly game of this scope is light on hardware by design, and that headroom suits a genre where input latency is the entire experience.

Steam-exclusive, with native Windows, macOS, and Linux/SteamOS builds — the last of which matters more than the store page implies. A native SteamOS build plus short, self-contained stages makes this a natural fit for Steam Deck. Levels fit inside a bus ride. Cloud saves mean the Deck-to-desktop handoff should work cleanly.

Controller is the correct input, full stop. Analog strafing and boost/brake modulation want a stick and triggers. Keyboard and mouse work, and the game is playable that way, but it converts an analog design into binary inputs at a cost in precision. Remappable bindings are a welcome and non-trivial courtesy for a game with this many simultaneous verbs.

One practical note for buyers: the campaign is short enough that Steam’s refund window may cover a large share of the content. Evaluate quickly and deliberately — that cuts both ways.

Ex-Zodiac is a better rail shooter than the genre’s neglect would suggest is possible, and its reputation rests on feel alone. MNKY has reverse-engineered something the industry decided was obsolete and made a case that it wasn’t — it was just abandoned. The controls are precise. The bosses are well built. The soundtrack is a legitimate piece of work rather than nostalgia bait.

What it isn’t, yet, is finished — and the missing pieces aren’t cosmetic. Branching routes and hidden areas were the load-bearing structure of the game Ex-Zodiac is modeled on. Shipping the flight model without the map is like building a good engine and leaving the chassis for later. It flies well in a straight line. That’s the problem.

We rate it a solid recommendation for the right audience: buy it for what’s on the disc today, understand the roadmap has moved slowly, and expect a control scheme that stands among the better ones in recent indie releases. If 1.0 delivers on branching, this could become a genre touchstone. Right now it’s a good game holding a good idea in escrow.
