It is much like its 3D predecessor Worms 3D, except that players can customize their worm's appearance (hats/helmets, glasses, facial hair, gloves/hands) as well as create their own unique weapons in a new feature called "The Weapon Factory".
É semellante ó seu predecesor en 3D Worms 3D, agás en que os xogadores poden personalizar a aparencia dos vermes (chapeus/cascos, lentes, cabelo, luvas/mans) así como crear armas únicas na "The Weapon Factory."
