DIESELFALL — twin-stick bunker roguelite for Android

The line

What it was for, and what was still running in it.

Recovered site survey

The line was built to run without people.

Weapons issue. Munitions. Transit. Power. And at the end of it, a command sanctum holding an autonomous defense core.

When containment failed, the core did not shut down. It executed the last instruction it still held.

Lockdown Protocol → Containment Failure → The Last Order

Your machine was not issued to you. It runs on what it takes off the floor — salvage between bunkers, and a dynamo that converts confirmed kills into armor.

And it runs on oil. Everything down here does.

Unaccounted for

Ashfall Yard The Breaker Yard · armored salvage and rail interdiction A sixth designation, on no campaign route. It turns up anyway.

The Command Echo Last Order · autonomous command and execution The core’s pattern, still answering in bunkers it was never installed in.

Warden Echoes

Every fifth bunker materialises an Echo, each with its own way of squeezing the arena.

Furnace Behemoth, a burning red-iron boss machine

Furnace Behemoth Warden Echo Grinds the range down and sweeps a slow, punishing arc.

Signal Seraph, a winged transmitter boss machine

Signal Seraph Warden Echo Reverses its orbit on every beat and jams the room from altitude.

Rail Tyrant, an armored rail-gun boss machine

Rail Tyrant Warden Echo Leads your movement and fires a rail line straight through it.

Aegis Revenant, a shielded duelist boss machine

Aegis Revenant Warden Echo A duelist, not a rusher. Its shield can be out-turned — never out-waited.

Also hunting the depths

Rivet Hound Tells laterally, then commits to a predictive pounce.

Siege Crawler, a walking mortar platform hostile

Siege Crawler Walks its mortar salvos across the floor in deterministic lines.

Six art kits — every floor and prop set is generated

Built to be played anywhere

The run you left is the run you come back to.

Every input

Touch, gamepad with rumble, or mouse and keyboard. Stick side, size, opacity, sensitivity and haptics all configurable.

Resume exactly

Autosaves every ten seconds and on pause, background or exit. Resume restores the arena, projectiles, hazards, timers and the RNG itself — not a rebuilt level.

Play offline

After the first launch the whole campaign runs offline, art kits included. Progress persists on the device and syncs when you sign in.

A ledger worth topping

Ranked Endless runs on server-issued seeds with per-wave receipts. The board never shows your account name — one of 6,400 callsigns instead, like Diesel-Warden-42.

Tune the pressure

Aim assist, deadzone, screen shake, flash intensity, reduced motion and an independent audio mix.

Read the run back

Every run closes with its build and combat metrics — and where it came apart.

The soundtrack

Thirteen tracks. Six bunker themes dealt in a different order every run.

Runtime49 minutes

Tracks13

Combat themesShuffled per run

Warden Time and Dieselfall never enter the shuffle — the Warden always sounds like the Warden.
