Players take turns controlling their team of worms with the ultimate goal of taking out the opposing team(s). The player must act within a time limit before the turn ends. During turns the player may move around and use one item. Items can either deal damage, increase mobility, or help protect the player. The landscape is fully destructible.
The game is largely based upon Worms 2: Armageddon (released on Xbox Live Arcade in 2009), but is said to be an 'extended edition of the console versions of late.'
