Gunpowder is a one-of-a-kind physics-based puzzle game set in a wacky rendition of the Wild West, in which players go head-to-head against the greedy wolf, Boss Grimshaw. Players take on the role of Incendio, a friendly fox inspired by the noble deeds of Robin Hood, to reclaim stolen riches for the people, using a series of carefully choreographed explosions ignited by gunpowder lines. Barrels and numerous environmental objects – flaming wagons, Gatling guns, chandeliers, cannons, mine carts and more - aid or hamper the effort! Gunpowder can be played many times over, as players seek to find the fastest and best way to solve each puzzle.
