be available each time a game is played, and differing selections of weapons and tools can be saved into a "scheme" for easy selection in future games. Other scheme settings allow options such as deployment of reinforcement crates, from which additional weapons can be obtained, and sudden death where the game is rushed to a conclusion after a time limit expires. Some settings provide for the inclusion of objects such as land mines and explosive barrels. When most weapons are used, they cause explosions that deform the terrain, creating circular cavities. The types of playable terrains include "island" (terrain floating on a body of water), or "cave" (cave with water at the bottom and terrain at both top and bottom of the screen that certain weapons such as "Air Strike" cannot go through; this type is not available in 3D versions due to camera restrictions). If a worm is hit with a weapon, the amount of damage dealt to the worm will be removed from the worm's initial amount of health. The damage dealt to the attacked worm or worms after any player's turn is shown when all movement on the battlefield has ceased. Worms die when one of the following situations occurs: When a worm enters water (either by falling off the island, through a hole in the bottom of it, or by the waterline being raised above the worm during sudden death) When a worm is thrown off either side of the arena When a worm's health is reduced to zero Weapons and tools The Worms series is notable for its extensive variety of weapons. With each new game that is released, weapons are added, though many were removed in the 3D versions for gameplay reasons. As a result, the 2D series has accumulated 60 weapons, and the 3D series 40 weapons. The weapons available in the game range from a standard timed grenade and homing missiles to exploding sheep and the highly destructive Banana Bomb, both of which have appeared in every Worms game so far. The Worms series has seen weapons such as the iconic Holy Hand Grenade, the Priceless Ming Vase and the Inflatable Scouser. Some of the bizarre weapons in a particular game are based on topical subjects at the time of the game's release. The Mail Strike, for example, which consists of a flying postbox dropping explosive envelopes, is a reference to the
