Heart Attack!

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Heart Attack!

Heart Attack! adds blood pressure, also referred to as "Fear Meter", that rises when the player is, well, scared. Or at least when you should feel scared.

If your blood pressure gets too high, you risk a heart attack, so be careful!

More versions

This mod is currently being ported by me to Forge 1.19 and Fabric 1.20.
