Half Heart Mod is a hardcore mod for Minecraft 1.8.9 that leaves the player with only half a heart (1 HP).
=The /hpone command activates a survival mode with permanent 1 HP even if the player dies in the world.
=The mod completely disables all health regeneration, works even on Peaceful difficulty, and adds cool activation messages on screen with a reference to a famous movie series.
=The mod works on Forge for Minecraft 1.8.9.
=There may be updates for newer versions up to 1.20.5, where Mojang added the ability to set 1 HP using commands.
✔The command currently requires cheats enabled or LAN mode!!
Stay tuned for updates :)
