Deck Forge

About this game

Forge your deck. Carve your path.
Deck Forge is a single-player roguelike deckbuilder set in a hand-painted dark-fantasy world. Start with a humble starter deck, draft new cards after every fight, bolt on game-changing relics, and venture through a world that never plays out the same way twice. Lose, learn, and forge a sharper deck on the next run.
Four classes, four ways to kill
• Warrior — A scrappy fighter of might and steel. Strikes hard, blocks harder, and stacks Strength to land devastating blows.
• Plague Doctor — Patient and methodical. Stacks Poison that ticks at end of turn and bleeds straight through Block.
• Warlock — Binds a Succubus to his will, a demoness who strikes anew each turn. Empower her, feed on souls, and let her tear the enemy apart.
• Sorceress — Channels arcane Orbs — Storm, Frost, Shadow, and Aether — that surge each turn. Stack Focus to amplify them, then unleash.
Build something dangerous
• 500+ cards across the four classes — attacks, skills, powers, curses, and class-defining mechanics.
• Relics that rewrite the rules — passive engines, build enablers, and signature relics unique to each class.
• Potions for the moment that would otherwise end your run.
• Upgrade at rest sites, thin your deck at the shop, and gamble on mysterious events.
Brave the trail
Three distinct acts — the Black Forest, the Caves below, and the seething Beehive — each with its own enemies, hazards, and a rotating cast of bosses, so the gauntlet keeps surprising you. Branching maps mean every choice between fight, shop, rest, treasure, and the unknown is a gamble with the run on the line.
Ten levels deeper
Beaten the gauntlet? Ascension mode layers ten escalating modifiers — tougher elites, leaner gold, nastier bosses, and a starting curse — for players who want the journey to bite back.
Features
• Four fully distinct classes, each with its own cards, mechanics, and signature relic.
• Hundreds of cards, relics, and potions to discover and combine.
• Three themed acts with rotating bosses and dangerous elites.
• Ascension 1–10 for escalating challenge.
• Full controller support, built with Steam Deck in mind.
• An original dark-fantasy orchestral soundtrack.
A note on Early Access
Deck Forge is in Early Access. The full loop is here and playable end to end — four classes, three acts, hundreds of cards, ascension. Early Access is about tuning the journey with your feedback: balancing card and class power, sharpening encounters, and adding more content on top of a solid foundation.
