Lethal Mystery (Alpha)

A murder mystery mod inspired by Among Us.

IMPORTANT NOTE: Because this is basically it's own gamemode, there's a high chance it may not work well with other mods.

If you want a place to play with other people, I've made this server:

I made a video summarizing my progress on the mod here:

Gameplay

Roles

At the start of the game you'll be given a special item if you have a unique role.

Note: I'm generally not a fan of having a ton of roles because I think it gets too distracting from the core gameplay so I may not add many others but a "Mimic" role is planned.

Employee

Objective

  • Reach the quota by carrying all the scrap you can find back to the ship
  • Vote out the monsters

Monster

Objective

  • Kill all the employees
  • Sabotage the crew to slow them down

Shop

Collecting scrap will give you credits which you can use to buy certain items in the shop

Meeting

When the round starts a horn will spawn. To call a meeting, you have to pull the lever.

Minimap

Your minimap will only allow you to see yourself and the actual environment around you.

You can scroll up and down to zoom in or out.

Important: During a meeting your minimap is automatically set to your last location. You can place a dot down somewhere on the map to let others know where you were. (This will also allow you to see other people's location)

Maps

To select a map, go to the terminal and type "moons" to see all your options (it automatically defaults to office).

To-Do

  • Hitting a vent with a shovel will force the monster out
  • Bomber role (probably). A monster type that can spawn a limited amount of landmines at a time

some other stuff too but Im not listing them all

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:
