Mob Drop Castle Previewed at BitSummit PUNCH
BattleBrew Productions showed its upcoming idle management game Mob Drop Castle at BitSummit PUNCH, held at Kyoto's Miyako Messe from May 22 to 24, 2026. The game combines monster raising with idle mechanics: players defeat invading enemies, collect resources, and unlock new monsters and characters. An interior decoration system lets players customize their castle, and certain furniture provides buffs when paired with specific monsters. Four secretary characters, each with illustrated portraits, can be recruited; they act as assistants, send reminders, and fight more powerfully than regular monsters. The player can also join battles by casting spells. The story is light-the player's demon lord wakes up in a castle to find noisy heroes invading and must drive them back with minions. A to-do list feature is planned to help the game serve as a companion for other tasks. Mob Drop Castle is scheduled for a 2026 release on PC.
