DROP64 3D

A downwell roguelite, born on the Commodore 64, rebuilt in 3D.

Fall. Shoot. Stomp. Don't stop. Play the demo above, free.

Watch: C64 vs 3D, side by side

You drop down a haunted mine shaft with gunboots strapped to your feet: fire jumps you off the ground, and in the air it shoots straight down, slowing your fall. Stomp critters, blast through rock, chain kills without landing, and grab the glimmer, the shards of the Lantern Stone that once lit the town of Lowmarrow, all the way down to whatever smashed it.

What's in it

The same game, frame for frame (the C64's code was traced to make sure), drawn in low-poly 3D with a camera that follows the fall.

• Everything the C64 Cartridge Edition has: eighteen worlds, 136 creatures, six bosses, the power stomp, the camp, the story and the ending.
• Three modes: EXPEDITION (all eighteen), CLASSIC (the C64's six) and the DAILY DESCENT: today's shafts, the same for everyone, one try.
• A death replay, an attract mode, keyboard, gamepad (with rumble) and touch controls.
• Every world its own light, weather and set pieces; the songs still come from an emulated SID.

Downloads: Windows and Mac; its own manual. Free demo: the first two depths: play it right here in your browser, or download it for Windows and Mac.

Made with Claude Opus 5.5

DROP64 3D was produced by Claude Opus 5.5, Anthropic's AI model, working in Claude Code. I gave the direction, played every build and reported what looked, sounded or felt wrong; Claude wrote all the code, the graphics, the music and the tools, and the tests that check the 3D game against the C64 original.
