Worms 4: Mayhem is as infectious and accessible as the classic Worms
  offerings! The multiplayer mayhem and single-player shenanigans are spread
  over five themed zones - Jurassic, Camelot, Arabian, Construction and
  Wild West and, throughout the enlarged landscapes, the entirely destructible
  scenery works with even greater effect, along with the much-loved worms
  armoury - now with an even bigger choices of weapons and fun along the way.
  In single-player modes there’s even more beyond the day-to-day business of
  destroying worms. Through the 25 missions, you’re also charged with
  objectives such as recovering items or smashing scenery. All the
  single-player maps are available to play in multiplayer mode, along with a
  further set of 20 multiplayer-specific maps.  With bold levels, an improved
  3D camera and animation system, a stunning arsenal delivering comedy
  kabooms, the loveable, customisable, yet entirely destructible, worms are
  back in force with Worms 4: Mayhem.
