Million Depth is a side-scrolling action-strategy roguelike from Cyber Space Biotope that enters Early Access on Steam on November 12, 2025, published by PLAYISM. Players control Moma, an outer-space visitor searching for her friend in the million-floor-deep underground world of Naraka Akasha, using a biotope jammer to freeze time for strategic combat and crafting. The game features modular weapon building, bartering systems, and multiple timeline-based endings, with a demo available since September for the first route.
