What is Lethal Cards?

Lethal Cards adds collectible trading cards to Lethal Company. Search facilities for booster packs and booster boxes, rip them open, hunt for rare cards and variants, build a persistent collection, and send your best pulls off for grading at the Company Building.

Lethal Cards is designed for multiplayer, and all players in the lobby should have Lethal Cards installed for everything to function correctly.

How It Works

  • Find booster packs and booster boxes inside facilities.
  • Rip booster boxes or booster packs to reveal four booster pack objects or three collectible cards respectively.
  • Collect cards across multiple rarity tiers and variants.
  • Grade valuable pulls at the Company Building. By default, grading takes 3 in-game days.
  • Build your collection and use the terminal's collection command to see what you've obtained.
  • Check submitted cards using the grading command and pick up completed graded cards once they're ready.

Features

33 Collectible Cards

Lethal Cards v1.0.0 includes a full 33-card Set 1, featuring creatures and characters from across Lethal Company.

Cards are divided into five rarity tiers:

  • Common
  • Uncommon
  • Rare
  • Ultra Rare
  • Secret Rare

Card Variants

Every card can appear as one of four variants:

  • Standard
  • Foil
  • Alternate Art
  • Misprint

Variants increase the value of a card, with rarer variants providing larger value multipliers.

Booster Packs

Every booster pack contains 3 cards.

Light Booster Pack

The standard booster pack, with mostly Common and Uncommon pulls while still offering chances at higher rarities.

Heavy Booster Pack

A more valuable booster pack with significantly improved Rare and Ultra Rare odds, plus a chance at Secret Rare cards.

Heavy Booster Packs also have a chance to become special high-rarity God Packs.

Booster Boxes

Standard Booster Box

Contains 4 booster packs.

Each pack has a chance to be either:

  • Light Booster Pack
  • Heavy Booster Pack

Golden Booster Box

Contains 4 guaranteed Heavy Booster Packs.

Grading System

Take valuable cards to the Company Building and submit them to the grading machine.

Cards receive a grade from 1 through 10.

Higher grades can significantly increase a card's final value.

By default:

  • Grading costs $10 per card
  • Grading takes 3 in-game days
  • Completed cards can be picked up from the grading return station

Graded cards are returned inside a collectible slab displaying information such as:

  • Card name
  • Variant
  • Set number
  • Grade
  • Grade descriptor
  • Final graded value

Persistent Collection

Your card collection persists between sessions.

Use the terminal to:

  • Browse collected cards
  • Search for specific cards
  • View collected variants
  • Navigate collection pages
  • Check grading status

Multiplayer Support

Lethal Cards supports multiplayer and synchronizes booster packs, booster boxes, pack opening, card rewards, collection updates, grading, and related gameplay across players.

All players should have Lethal Cards installed.

Configuratio

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:
