Greenbullet’s hack-and-slash action game Ghost Eater is opening a public playtest during September 2026, giving players a hands-on look at its black-and-white, manga-styled combat. The playtest sign-up runs through Steam, and the build shown off covers aerial combos, a post-battle scoring screen, an upgrade shop, parkour traversal, new enemies, and a boss fight.
Quick answer: Open the Ghost Eater Steam page, click Request Access under “Join the GHOST EATER Playtest,” and you’ll be notified when the developer opens more participant slots.
How to join the Ghost Eater playtest on Steam
Access is handled entirely through the game’s Steam store listing. There’s no key to redeem and no separate launcher. You request a slot, then wait for the developer to invite you in waves.
You’ll know the request went through when the button switches to a pending or granted state on the store page. Actual play access arrives later through the Steam notification once a new wave opens.
A full release date has not been set. The store listing lists the launch as “To be announced,” so the playtest is currently the only way to try the game.
What the playtest build includes
The playtest leans on fast ground-and-air combat that blends sword combos with firearm shots. The whole game is rendered in a monochrome, high-contrast style that mimics printed manga, complete with screentones, crosshatching, speed lines, and sound-effect lettering.
Air combat and combos
You can knock crates and enemies into the air, follow them upward, and chain airborne juggles before finishing with a slam. A combo counter tracks your hits and flags them with cues like “CRITICAL!”, “MIXUP,” and “FINAL STRIKE.” Basic controls map attacks to X, jumps to A, and skills to holding LT while pressing X.
Traversal and traps
Between fights, the protagonist sprints, wall-runs, vaults over structures, and mantles ledges through a training facility. Arenas also hold interactive hazards you can trigger to fling enemies into the air and continue a combo.
New enemies and a boss
Encounters mix scripted and randomized arena battles against mechanical foes, including quadrupeds, turrets, and large airborne drones. The build also shows a boss labeled the APP SEC COMPLIANCE DAEMON, with a health bar reading 1817 / 4200. The full game is planned to feature 24 distinct enemy types and 6 bosses.
Battle scoring and the S rank
Finishing an encounter opens a results screen that grades your performance and awards a letter rank. The demonstrated run scored a RANK S with a total of 768 points. Scores draw from several categories shown on the breakdown.
| Metric | Sample value |
|---|---|
| Completed in | 01:24 38 |
| Damage taken | 0 (200) |
| Damage dealt | 11400 (227) |
| Highest combo | 15 (75) |
| Squibs collected | 806 |
| Perfect dodges | 3 (45) |
| Environment kills | 1 (25) |
| Battery spikes | 1 (8) |
| No heals bonus | 150 |
| Total | 768 (Rank S) |
Clean runs are rewarded twice over. Dodging perfectly, using the environment to kill, and clearing without healing all feed the score, so aggressive play with no damage taken pushes you toward the top rank.
Weapons in Ghost Eater
Combat is built around one main weapon class supported by three secondaries. The main blade carries a five-hit combo with slot-able combo enders and other contextual moves, while each secondary class runs a three-hit combo and its own weapon skill.
| Weapon type | Role | Combo |
|---|---|---|
| Single-edge blade | Main weapon | 5-hit, slot-able enders |
| Dual blades / daggers | Secondary | 3-hit, fast slashes |
| Two-handed greatsword | Secondary | 3-hit, heavy hits |
The developer notes the combat avoids “dial a combo” inputs, so strings come from timing and mixups rather than long memorized sequences.
Upgrades at the F.F.F.FABBIT terminal
Credits you collect in combat are spent at a store called F.F.F.FABBIT, split into Skill and Ranged tabs. Purchases cover ammunition caches, offensive modules, and abilities. Some modules also draw on a battery charge to fire.
| Item | Cost (credits) | Battery |
|---|---|---|
| SpinStrike | 1200 | — |
| Ammo 10 / 20 / 40 | 200 / 340 / 500 | — |
| Burst | 400 | 2 |
| Satellites_A | 1320 | — |
| Missiles | 3000 | 4 |
Burst deals 60 Plasma damage in the immediate area, while Missiles launch a burst of seeking projectiles. Because battery-powered skills compete for the same charge, you choose which modules to trigger during a fight.
PC system requirements
Ghost Eater is a Windows title with full controller support, and the playtest build is single-player. Here is what the store listing states for hardware.
| Spec | Minimum | Recommended |
|---|---|---|
| OS | Windows 10+ | Windows 10+ |
| CPU | Core i5-3570K / FX-8310 | Core i7-8700K / Ryzen 5 3600X |
| RAM | 8 GB | 8 GB |
| GPU | GTX 780 / RX 470 | GTX 1070 8GB / RX Vega 56 8GB |
| Storage | 2 GB | 3 GB |
The game requires DirectX 11 and a Windows-compatible audio device. Blood and profanity are present, and the blood can be toggled off in the options.
Story and what to expect from the playtest
Story beats play out through 2D illustrated manga panels rather than long cutscenes or voice-over. You control a fixed female protagonist with short dark spiky hair, a white collared shirt, and dark trousers, armed with both a sword and a firearm. Dialogue introduces characters such as Mako, alongside a wheeled monitor robot.
The narrative is described as a branching story tied directly to the combat, so choices carry into how encounters play out. Clearing a fight ends with a “CLEAR” banner, confirming the encounter is complete and your score is locked in.
If you want in during the September 2026 window, requesting access on the Steam page is the only step required. Once the developer opens more slots, the invite lands in your Steam notifications and the build shows up in your library ready to install.
