Squad Busters is a mobile party action game developed and published by Supercell, released globally on May 29, 2024. It serves as a crossover title featuring iconic characters from other Supercell games including Clash of Clans, Clash Royale, Brawl Stars, Hay Day, and Boom Beach.\n\nGameplay centers on fast-paced 4-minute matches where players build a squad of characters called Squaddies by collecting coins and opening chests on the map. Collecting duplicate Squaddies fuses them into powered-up versions, while the ultimate goal is to gather the most gems by defeating monsters, other players' squads, and looting the environment.\n\nSquaddies fall into distinct classes — Fighters, Hotshots, Suppliers, Healers, Speedsters, and Summoners — each filling a different tactical role. A later major update introduced Heroes, which are super-charged versions of beloved characters like Barbarian King and Archer Queen, adding deeper strategic choices to squad composition.\n\nNote: Supercell announced in October 2025 that Squad Busters would be sunset, with servers scheduled to shut down in the second half of 2026.
