Four squads of worms face-off against each other during each game. Teams can be controlled by players or the computer. During battles, turns alternate with every player receiving 60 seconds to move each worm. Weapons available for use include: grenades, Uzis, missiles, bombs, dynamite, and bazookas. Most weapons must be aimed with a cursor.
Options allow players to: name their worm squad, choose between three difficulty settings, set the number of ammunition rounds per weapon, turn on unlimited ammunition, as well as switch to Banzai mode. Banzai mode causes all of the explosions to double their destructiveness.
