About this mod Author’s original text

Heart Attack

But configurable

Please let me know of any issues or feature requests on the LC modding discord.

This mod adds in a slim chance (default 5%) for the player to instantly die upon getting scared, and a slightly bigger chance (default 13%) for the player to suffer 'tremble' effects instead. Additionally, there is now a chance (default 15%) for an 'Adrenaline' rush.

The heart attack and other effects can be individually modified by config.

Trembling causes lower movement speed for a short period of time. It also drains stamina, even while walking or standing still.

Adrenaline rush causes increased movement speed for a short period of time, and can be configured to cause the tremble effects as it ends as a balance.

Also has compatibility with Coroner - simply have Coroner installed and the mod will add death messages if it can!

Roadmap:

  • [x] Change heart attack chance via config
  • [x] Chance tremble chance via config
  • [x] Change tremble move speed via config
  • Change heart attack from instant kill to just damage
  • Introduce extra effects for both heart attack and tremble
  • [x] Use a specific cause of death that works with Coroner
  • [x] Add in a chance for an adrenaline rush
  • Add in alternate affects
  • Play audio
  • Make it more obvious you died to a heart attack (even without Coroner)

The original mod was created by nono_t27.

I forked his project and updated the code to work with configuration files for the existing values,

and I plan to add more content in future.

ORIGINAL MOD DESCRIPTION:

Lethal Company Heart Attack

Adds in a heart attack difficulty tweak aka RNG.

Technologies:

  • C#
  • Unity
  • BepInEx (THIS IS REQUIRED FOR THE MOD TO WORK PROPERLY)

ALL CREDITS TO ORIGINAL MOD:

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.

Dependencies

Install these first, or the mod will not work:
