Slay the Demon Kings

Slay the Demon Kings is a single-player game that combines party-based RPG combat, deckbuilding, and roguelike elements.

Lead three amnesiac adventurers who share a hand and Action Points. Make your choices before enemy countdowns reach zero. Collect cards, legendary weapons, and treasures, venture deep into the remnants of the Demon King's domain, reclaim your lost power, and kill everything that stands in your way.

Choose three characters from a cast with radically different combat styles and assemble your own party.

Each character has unique stats, cards, and progression paths. Some excel at taking hits, some heal allies, while others rely on critical strikes, poison, control, or special status effects to end battles.

All three characters share one deck, one hand, and one pool of Action Points. How you spend limited resources, when you protect an ally, and when you concentrate your strength on offense will determine how far the party can go.

Each character has 13 class cards and 2 Masterstroke cards, which together form their unique combat system.

Every class card offers 3 distinct upgrade paths. Depending on your party composition and build strategy, the same card can evolve into dramatically different effects: becoming the core of a character's build, covering a party weakness, or creating new synergies with other characters.

The game also includes 41 neutral cards. They belong to no specific class and can be freely added to the party deck, providing new tools for an existing strategy or forming the foundation of an entirely new archetype.

Choose different cards and upgrade paths to build a combat system truly your own under the shared-hand and shared-Action-Point rules.

Cards are only one part of your build.

Find and forge different weapons, equip treasures with unique effects, and carry consumables capable of turning the tide. Attack, Spirit, Critical Rate, and many other combat stats all change with your equipment.

A legendary weapon can completely transform how a character fights, while an unassuming treasure may become the heart of an entire archetype. Combine cards, equipment, and treasures to create a different progression path on every journey.

Enemies will not stand quietly and wait for your turn to end.

Every action pushes their countdowns closer to zero. The moment a countdown reaches zero, that enemy acts immediately. Read enemy intentions, control the order of your actions, and kill, interrupt, or disable them before they can strike.

When an ally falls, they do not immediately leave the battle. That character's cards transform into rescue actions, forcing you to choose between pressing the attack and bringing your companion back.

Pass through unknown events, dangerous elites, and powerful enemies waiting at the end of the road.

Enter their territory. Leave none alive.
