Rats Mod

Warning: These arent your normal rats, they have evolved in order to survive the harsh moons of Lethal Company

Behavior

Spoilers

  • Rat Nest: A rat nest can spawn on any map as a map hazard which will spawn rats every x - x seconds.
  • Rat Types: Each rat will either defend the nest or scout the dungeon. If a player gets too close to the nest, they will damage the player.
  • Colony Threat System: Each time a rat sees a player or enemy, they will add 1 to a threat counter. When that reaches a threshold (100 for players and 50 for enemies by default) they will start swarming the threat.
  • Rat Food: If a rat finds a player corpse it will attempt to drag the corpse back to the nest. They will rip food off of enemies depending on the enemies HP. By default, player corpses give 30 food and enemies give 10 * enemyHP food. For every 10 food brought back to the nest, it will spawn a rat.
  • Infestation: Each time you leave a moon, the infestation level (amount of rats) will be saved. This means when you land on the same moon later, it will spawn that many rats again.
  • Rat Control: You can control the rat population with traps and poison.

Items and scrap

  • Box Of Snap Traps: Buyable equipment. Allows you to place snap traps to kill rats. Killing rats this way does not increase the threat counter.
  • Glue Traps: Buyable equipment. Allows you to place Glue Boards to slow and kill rats. Each stuck rat increases the scrap value of the glue board and it can be picked up and sold for profit. Killing rats this way does not increase the threat counter.
  • Rat Poison: Buyable equipment. You can pour this into a rat nest to prevent them from spawning.

Planned features

  • An actual rat king (if you dont know what I mean, search up rat king on google if you arent squeamish)
  • Diseased rats that can make the player get sick, lowering stamina and making them cough, etc.
  • Outside rats: Chance for rat nests to spawn outside as vain shrouds. Keeping these under control will require weed killer or traps.
  • More rat types?
  • More configs for performance.
  • Achievements!
  • Mutated rats (cadaver rats)

NO RATS WERE HARMED IN THE MAKING OF THIS MOD

Rat Poison and Glue Traps just put the rats to sleep and Snap Traps just teleports the rats to New York and replaces them with a plushie:)

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.

Install these first, or the mod will not work:
