AI-Usage Notice

AI was utilized to help build the code logic behind the mod. All card artwork itself was done by hand. AI was used to generate the booster box and booster pack art for those item assets themselves, but not the 33 individual cards.

Hunt for Packs. Rip Them. Collect Cards. Grade Them.

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

  1. Find booster packs and booster boxes inside facilities.
  2. Rip packs to reveal three collectible cards.
  3. Collect cards across multiple rarity tiers and variants.
  4. Grade valuable pulls at the Company Building. By default, grading takes 3 in-game days.
  5. Build your collection and use the terminal's collection command to see what you've obtained.
  6. 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.

Configuration

Lethal Cards includes configurable balance and spawn settings.

Configuration files are generated through BepInEx after launching the game with the mod installed.

Scrap Spawn Weights

Default v1.0.0 spawn weights:

  • LightBoosterWeight = 45
  • HeavyBoosterWeight = 25
  • BoosterBoxWeight = 20
  • GoldenBoosterBoxWeight = 10

These are relative spawn weights, not direct percentages.

Setting a spawn weight to 0 disables that item from naturally spawning as facility scrap.

Existing configuration files may preserve values from older versions, so check your config after updating.

A game restart is recommended after changing spawn settings.

For multiplayer, the host's gameplay configuration should be treated as authoritative.

Booster Values

Default booster and box values:

  • Light Booster Pack: $30
  • Heavy Booster Pack: $50
  • Standard Booster Box: $75
  • Golden Booster Box: $150

Grading Configuration

The grading system can be configured, including settings such as:

  • Grading cost
  • Grading turnaround time
  • Grade probabilities
  • Grade value multipliers

Default grading turnaround:

3 in-game days

Default grading cost:

$10

Variant Odds

Default card variant rates:

  • Standard: 69%
  • Foil: 25%
  • Alternate Art: 5%
  • Misprint: 1%

God Packs

Default Heavy Booster God Pack chance:

5%
