Somewhere between Slay the Spire and Into the Breach, Cards of the Abyss is a roguelike tactical deckbuilder set in the heart of an ancient Abyss.

Awaken in the depths of a forgotten world and descend ever deeper into the Abyss - a gigantic chasm carved out by a vanished civilization. Control a lone hero on a battle grid, dodge enemy attacks and chain card combos to survive... and reveal the secrets of a petrified past.

In Cards of the Abyss, cards control your movement as well as your attacks. Positioning, anticipation and sequencing are essential to triumph.

Enemies reveal their intentions in advance: it's up to you to adapt your strategy to avoid attacks, interact with objects on the ground, exploit opposing Tactical Zones triggered by movement... and unleash devastating combos at just the right moment.

Each run is divided into three acts, each with its own enemies, bosses, events and rewards. Each act is made up of procedurally generated nodes:

• Battles

• Elite

• Treasures

• Events with multiple choices

• Shops

• Campfires

• And of course... a Boss!

Special Mini-Biomes may appear, bringing unique modifiers to the environment: burning terrain, gold mines, plant invasions... as well as much more tempting rewards!

Choose from hundreds of cards, upgrade them, and evolve your deck as you fight. Find powerful synergies, unlock relics with profound effects, and experiment with multiple approaches for every situation.

Each playable character is different, offering a unique playing style and card pool. And through your runs, a persistent main quest will unlock new options, bonuses and mechanics over the long haul.

All the cards in the game feature an integrated GIF animation, which is triggered on hovering to visually illustrate their effect - making even the most obscure effects crystal clear.

The Abyss was once a refuge built by the Ancients to survive the Eruption. But their hope of one day awakening was shattered when the Clepsydra, the source of resurrection, was destroyed.

Since then, their people have been frozen, Crystallised forever.

Today, new creatures, altered by the magical energy of the place, haunt the depths. Guided by the telepathic voice of Nyssara, an ancestral dragon, you are the only one who can descend to the bottom of the abyss... and perhaps rekindle the Clepsydra.
