Overview

Cutthroat Caverns is a semi-cooperative card game where players form a party of adventurers fighting through a series of 9 encounters. The party must work together to survive each monster, but only the player who lands the killing blow earns the Prestige Points. The player with the most Prestige Points after defeating the final encounter wins. “Without teamwork, you’ll never survive. Without betrayal, you’ll never win.”

Components

Setup

  1. Shuffle Initiative cards equal to the number of players (remove highest-numbered cards first) and fan them face down on the table.
  2. Shuffle the remaining cards (Attack, Action, Item) and place them face down as the draw deck.
  3. Each player draws 7 cards as their starting hand.
  4. Shuffle the Encounter cards and deal 9 face down to form the Encounter deck.
  5. Each player takes a Character Sheet and places a green bead on 100 Life Points.
  6. Place the Monster Life Tracker on the table with yellow beads for creature LP and encounter number.

Turn Structure

Each encounter follows this sequence:

  1. Begin a New Encounter – Reveal the top Encounter card, read it aloud, set creature LP on the Monster Life Tracker based on player count. Players may use Potions. Draw Initiative cards.
  2. Combat Round – Set Attack cards, resolve Player Turns, Total Attack Damage, Creature Attacks, Draw Initiative for next round, Draw a card.
  3. End of Encounter – Award Prestige Points, discard/draw cards, advance to next encounter.

Actions

Set Attack Cards: Each player places 1 Attack card face down. Cards may be changed before the first is revealed but never after. If you have no Attack cards, set an Action card as a bluff (discarded without effect).

Player Turns: In Initiative order (starting with Player 1), each player flips their Attack card and inflicts damage or follows card instructions. Successfully played Attack cards go onto the damage stack beside the Encounter card.

Total Attack Damage: Sum all Attack card damage and adjust the creature’s LP. If the creature survives, it attacks according to the Encounter card’s rules.

Card Types:

Priority: If multiple players want to play a card simultaneously, the player with the Initiative card closest to 1 takes priority.
