Mine

The Land Mines are weapons that are dropped onto the terrain, in the hope that later, some unfortunate worm will trigger it and damage itself.

Usage

 * After you have placed the mine, remember to retreat or the mine will explode after your turn ends.
 * The Mines are generally used more as a deterrent than an actual weapon, and are considered part of the 'Dark Side' style of play.

Mega Mine
A Mega mine is just the same as a land mine, and can be used exactly the same. Either plant it next to somebody, or plant it somewhere where your enemy is most likely to walk. Mega mine does more damage.

Trivia

 * Some worms players have taken to planting land mines on the heads of their opponents so they look like a cap, as a type of bizarre humour.
