ULB: Mobile Edition

ULB: Mobile Edition is a faithful mobile port of Undertale: Last Breath (ULB) that bundles Legacy, Canon, Preview, Beta and Alpha builds into a single playable release. This edition is released with express permission from the current ULB owner and preserves the project’s art, music, writing and QoL improvements. Recommended: play UNDERTALE first for full context. Warning: the game contains flashing lights and fast-moving imagery—play at your own risk.

This release highlights community-driven development and credits the original creators, porters, coders, artists and testers behind the project. Join the active community for updates, support and testing via the project’s Telegram and Discord channels. ULB: Mobile Edition is designed for fans of pixel-art RPGs, narrative-driven indie games, and Undertale-inspired experiences on mobile devices.
