MeatSlicer: A Butcher's Descent

Clear, harvest, descend.

MeatSlicer is an endless top-down arena roguelite. You are the Butcher, descending floor by floor through an infinite meat-locker hell: clear rooms of flesh-hungry horrors, draft mutations, stack grotesque passive items into a broken build, kill the boss, take the stairs. The descent never ends — the only question is how deep you get before you're butchered, and whether your score becomes the new best cut.

Debug console

An in-game cheat/inspection panel is available in dev builds. Launch with the dev flag — MeatSlicer.exe --dev, npm start -- --dev, or play-dev.bat / http://localhost:8123/?dev=1 in a browser — then press the backtick ` key in play or pause. Eight tabs cover health, weapons, items, perks, pressure, spawning enemies/bosses, timescale, visualizers, and a live stats readout. Using mutating actions voids the run's best score. See Debug Console.

The fantasy in one paragraph

Rooms lock behind you. The meat waves come in threes. Elites gleam gold and drop the good stuff. Set the Pressure Dial before you descend — the gauge climbs the longer you stay flawless, and every point of score rides it. Every boss — saw, crown, mother, flenser, choir, father, auger, scald — cycles back around, deeper and meaner, until the meat finally wins. Take the meat. Take the stairs.
