Cardboard Conquest is a roguelite deckbuilder where your cards muster, march, flank, and die gloriously on a living battlefield. Draft themed packs, plan your deployment, slam End Turn, and watch the clash auto-resolve. Climb a branching war map, break seven act bosses, and take the crown. Solo, or in online co-op with up to four warlords.

You drop each card straight onto the battlefield, and a squad of soldiers, a spell, a trap, or a siege engine springs to life right where it lands. Wall a chokepoint, flank the line, screen your archers, and let the battle play out in real time.

Spells and statuses turn a losing clash. Rain meteors on a packed line, then stack Poison, Bleed, Fragile, and Charm until the enemy melts before your commander ever takes a hit. 275 relics and a 33-potion belt bend the rules further, every run.

Every run opens with a draft: themed card packs — armored legions, spider broods, walking bombs, con artists, love sorcery, splitting slimes, rising ghosts — and together they become your entire card pool. Even your commander is assembled from the packs you pick, so no two runs look or play the same.

Every act boss hides a signature phase that flips the fight. Cut Rex Mortifer to half health and the dead rise; strike Verdy B. Queen and the whole garden erupts. Seven bosses across three acts stand between you and the crown, and forty-two named lords bar the road to them: slime tides and spider broods, con artists and brass colossi, banshee choirs and the Pale Rider. Each one fields its own army, fights its own way, and packs its own dirty trick.

March as a war council of two to four. Every warlord drafts their own packs and plays their own hand, but you share one battlefield, one map, and one fate. Vote your route, suggest picks in a friend's draft, scrawl battle plans straight onto the field, and hold the line together: the clash begins when every crown is ready.

The road between battles bites back. 124 hand-written events — haunted shrines, crooked gamblers, going-away gifts from Uncle Jim, and a wheel of fate that can crown you or curse you. Read the room, weigh the odds, and decide what your army is willing to pay.
