Half Heart mode

Once the mode is activated, the player's maximum health drops to a single point of health, and natural regeneration is switched off. The limit applies on Peaceful difficulty as well, so the restriction stays in place even where enemies cannot attack. A player who dies while the mode is active keeps the same one-point limit after respawning, so the challenge carries over from one life to the next.

Activation happens through a command. Survival mode with the permanent one-point limit is turned on with that command, and the server operator decides when it is used. The command requires cheats to be enabled, or LAN mode, so it is not available on a standard server without those settings. A messages screen shown during activation carries a reference to a well-known movie series.

Half Heart mode is published for Forge on 1.8.9 only, with a single file dated 2026-05-15. It is server-side only, so players join a server running the mode without installing anything. The mod is distributed under All rights reserved and is not open source, although a public link to its source code exists.
