Do Not Eject is a retro handheld-inspired bullet heaven roguelite. Enter corrupted game cartridges with a digital partner, stack projectile-changing Modules and Patches, defeat corrupted guardians, and turn every run into permanent progress.
BOOT THE CARTRIDGE. CHOOSE YOUR PARTNER. DO NOT EJECT.
Do Not Eject is a retro handheld-inspired bullet heaven roguelite where corrupted game cartridges have trapped living digital creatures inside.
Choose your partner, insert a cartridge, and fight through waves of corrupted programs as your attacks evolve from a handful of projectiles into ridiculous combinations of ricochets, orbiting weapons, explosions, piercing shots, and chain reactions.
Defeat the corrupted guardian waiting at the end of each cartridge, restore it to the console, and unlock it as your next playable partner.
BUILD SOMETHING ABSURD
Every run starts small.
As you survive, you’ll install powerful Modules that fundamentally change how your attacks behave, stack Patches that strengthen your build, and equip Auxiliary Chips that add entirely new elemental interactions before the run even begins.
No two runs need to play the same.
A simple projectile can evolve into a screen-filling storm of bouncing, piercing, homing, exploding, and orbiting attacks. Automatic stat growth keeps the pacing fast, letting you focus on movement, positioning, and choosing the upgrades that create your next broken build.
RESCUE YOUR DIGITAL PARTNERS
Every cartridge hides a corrupted creature waiting to be restored.
Defeat its guardian to purify the cartridge and add that partner permanently to your collection.
Each playable partner features:
A unique weapon and combat style
A defining passive ability
Exclusive Modules
A permanent Memory Tree
New interactions with every Auxiliary Chip
The planned full game features ten elemental cartridges, each introducing a new partner, enemy roster, boss, and set of build possibilities.
EVERY RUN MOVES YOU FORWARD
Even failed runs matter.
Collect Data Bits, Core Shards, and Creature Mastery during every attempt, then return to upgrade your console, unlock new Auxiliary Chips, and permanently strengthen your favorite partners through their Memory Trees.
Failure isn’t a reset.
It’s another step toward rebuilding the console.
THE CORRUPTION NEVER STOPS GROWING
Restoring a cartridge is only the beginning.
Increase its Corruption Level to face faster enemies, tougher bosses, and increasingly dangerous encounters that push every build to its limit.
How much corruption can your favorite partner survive?
A CONSOLE WORTH SAVING
The console itself is your home.
Manage restored partners inside the Habitat, browse your discoveries in the Archive, improve your hardware through the Kernel Terminal, and slowly bring the abandoned system back to life one repaired cartridge at a time.
