Prototype: Pain
by AdInVas
Prototype: Pain replaces the heart-based health bar with localized limb damage, so injuries to specific parts of the body matter in play.
What it does
Rather than watching a heart meter drain, players contend with bleeding, broken bones, joint dislocations, pain and infection. The mod describes its aim as a harder, grittier survival experience in which injury has lasting consequences. Core parts include localized damage, a bleeding and trauma system, a pain mechanic, a consciousness mechanic, a healing system and multiplayer support.
The mod is heavily inspired by the First Aid mod for Forge and the Casualties mod, and the author calls it a total rework of Minecraft's health damage system. It is in early development, so the author warns that bugs and missing features should be expected, and feedback is requested to shape the future of the mod.
Prototype: Pain is a Forge mod for 1.20.1 only, released under the MIT License and open source. Every player and the server need a copy of the mod. Serene Seasons and Simple Voice Chat are optional dependencies and can be added for extra integration.
Key features
Localized limb damage
Damage is tracked per body part, so an injury to one limb does not drain a shared health total.
Bleeding and fractures
Wounds can bleed and bones can fracture, each with its own effect on the player's condition.
Pain and consciousness
Pain and a consciousness mechanic reflect the player's state after an injury, with healing handled by a dedicated system.
Infection
Infection is part of the injury system, adding a longer-term threat after a wound is left untreated.

Use cases
