Half Heart Hardcore
by super4z
Half Heart Hardcore caps a player's maximum health at half a heart once a world has the datapack enabled, and a player who dies ends the run for everyone.
What it does
The mod is a datapack, so it changes a world rather than the game code. After it is enabled, each player has only half a heart of maximum health. The datapack is aimed at a 1 HP challenge and is meant for multiplayer: because one death affects every player, the group has to stay careful throughout. It can also be played in singleplayer, where it is a challenging run with no friends involved.
Totems of undying work in an altered way with this datapack. Two players can share a single totem, so one of them can be saved from death while the other keeps the totem, and a player holding a totem can be spared when a friend dies. The server needs the datapack, while a client may skip it, so the mod is a server-side install. Released under the MIT License, the code is open source and published for 1.20 – 26.2 across 23 release versions.
Key features
Half-heart maximum health
Once the datapack is enabled in a world, every player is limited to half a heart of maximum health.
Shared consequences
When one player dies, every other player dies too, so the whole group shares the risk.
Altered totems of undying
A totem can save one player from death, and a single totem can cover a friend who would otherwise die.
Multiplayer challenge
The datapack is designed for groups playing hardcore together, and it also works for a lone player.
