Iron Descent is a classic roguelike dungeon crawler for your pocket. Every run drops you into a freshly generated labyrinth where one wrong step can end everything. Choose your hero. Descend into the dark. See how deep you can go. **CHOOSE YOUR CLASS** Three heroes, three ways to play: • Warrior - heavy armor, heavy hits. Wade into the fray and outlast anything. • Rogue - fast, deadly, and dripping with poison. Dual-wield your way through the horde. • Mage - bend the dungeon to your will with a spell book of destruction, restoring mana with every kill. **DESCEND 10 DEADLY FLOORS** The dungeon is never the same twice. Rooms, corridors, traps, and treasure are procedurally generated every run, so no two descents play alike. Explore by torchlight, reveal the map one tile at a time, and never trust an empty room. **FIGHT - OR DIE** Orcs, trolls, goblins, rats, and worse prowl the depths, each with its own behavior. Some hunt you the moment they catch your scent; others lie in wait. That chest in the corner? It might have teeth. Face down the Orc Warlord at the dungeon's midpoint and the Demon Lord waiting at the very bottom. **LOOT, GEAR, AND GLORY** Crack open chests, gather gold, and equip weapons, armor, and rings suited to your class. Sip potions, read scrolls, and pray at shrines for a blessing - or a curse. Every upgrade is another step toward surviving the descent. **RETURN TO TOWN** Between runs, regroup in town. Shop for fresh gear, pay the healer to patch your wounds, and take on quests from the board for extra gold and glory. Then it's back down into the dark. **CLAIM THE DARK CRYSTAL** Deep beneath the earth lies the Dark Crystal. Reach it, seize it, and carry it back to town alive to claim victory. Few will make it. Will you? **FEATURES** • Three distinct classes with unique playstyles • 10 procedurally generated floors - endless replayability • Two epic boss battles • Traps, mimics, shrines, and hidden loot • A hub town with a shop, healer, and quest board • Striking retro dungeon visuals and an atmospheric original soundtrack • Save and continue your run anytime • Fully playable offline Grab a torch. Draw your blade. The descent begins.
Aetherium Hearts
Read full descriptionHide full description
Raise adventurers in Selwyn, town of the Ash Marches, and send them down into the labyrinths. The expedition runs by itself — they walk, they fight, they gather, and sometimes they fall. Those who come back bring the whole of it with them, written up by an AI as a single tale. No two are ever the same. ◆ Three labyrinths The Ashen Corridor, the Frostcrystal Archive, the Ember Crucible. Each runs to a different depth and a different danger, and at the bottom of each an Aetherium Heart lies sleeping. ◆ It runs on its own Once they are down there, they walk and fight on their own feet. The descent continues while the app is closed. ◆ Tales The record of a returning expedition is woven into prose by an AI. Send it straight to X, Threads, Bluesky or Discord. ◆ The town and your company An armoury, a general store, a forge, the guild, a temple, a shrine — Selwyn holds nine places to go. You can also go looking for an adventurer who has gone missing. ◆ Standings Set the Aetherium Hearts you have offered at the Shrine of Astel against every adventurer in every town. Japanese and English, switching with your device. Free to play, with no in-app purchases.
