Worms 4: Mayhem is a 3D artillery game in the Worms series developed by Team17. It is much like its 3D predecessor, 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 an added feature called "The Weapon Factory." The game also contains a shop where users can buy various items, using points won by completing story missions, activities or unlocking trophies. Shop items include new maps, new accessories and attire, personality banks (voices) and game styles. There are several new weapons included in the new game such as Bubble Trouble, Icarus Potion, Poison Arrow, Sniper Rifle, Inflatable Scouser, Tail Nail and Starburst. You can even create your own weapons, teams, and game styles, and customize how your team's worms look! [source:wikipedia]
