Worms Armageddon is an artillery strategy game developed by Team17 and part of the Worms series. During a single turn, a team can only move one of its worms . When hit with a weapon, the worm will lose health depending on the power of the weapon and the directness of the hit. The game includes a wide variety of weapons, including melee, projectile, and explosive weapons, as well as airstrike-based attacks. In a normal match, all teams begin with the same weapons, based on the chosen weapon set. In addition to normal weapons, each team chooses a special weapon which becomes available to them after a certain number of turns.
