1 Heart!
by belcher.jon
1 Heart! is a NeoForge economy-category mod for 1.21.8 that caps player health at a single heart, turning the standard survival game into a one-hit-away challenge.
What it does
Players start each run with the base maximum health set to exactly one heart, so a single unlucky hit, fall or creeper blast can end the run. The mod removes the usual safety net of the vanilla health cap, and the health bar drops to a single fragile heart from the start.
Golden Lifelines keeps natural red hearts locked to the same limit, so only Enchanted Golden Apples raise the cap as a saving resource, while regular Golden Apples and the God Apple still grant temporary Absorption hearts as a brief buffer. Survival, Adventure and Hardcore modes all work with it, and it is aimed at hardcore challenge packs.
The mod is server-side only, so players join a server running it without installing anything. It is published for NeoForge 1.21.8 as All rights reserved, not open source, and was first released on 2026-05-30 with its only file, version 1.0.0, on the alpha channel.
