The modes of the game are Puzzle, Campaign, Laboratory (DS only), and Training. Puzzle mode consists of over twenty challenges that require the player to complete a specific task, such as reaching an exit point or killing hard-to-reach enemy worms, with limited resources. The campaign is a series of thirty typical gameplay missions (plus 5 buyable missions in the in-game shop) with a basic story. The campaign introduces and moves through each of the landscape environments. Laboratory is unique to the DS. This has four different sets of mini-games which utilize unique characteristics of the DS - one mini-game type has the player flying a worm through a cavern, blowing into the microphone to raise the worm's parachute to clear obstacles. Training consists of a series of three missions designed to familiarize players with the gameplay and control scheme, as well as several "shooting range" levels which give the player unlimited access to every weapon, and allow the player to spawn targets to test the weapons on.
