Bomb Farm is a free-to-play idle RPG in which a squadron of bombers gathers resources on its own. Players destroy rocks to collect materials and hunt for rare items, forge and upgrade equipment from +0 to +15, and develop their characters through a large skill tree. Squads are built from heroes of different rarities, each with its own set of upgradeable passive abilities. Progression spans five worlds and five difficulty levels across 600 stages. Items can be traded with other players through the Steam Community Market.
