From Worms Knowledge Base
A standard mine in every way except that when it explodes, another 3-second fuse time mine flies out of the wreckage and is primed instantly. This happens as a chain reaction with mine after mine until the nth mine is the last one and explodes without any further malicious mine mayhem.
Shouldn't be too hard to make new mines just 'appear' in the game.
Not much strategy in this one, it just has a good chaos potential. Useful for a group of enemy worms, but any decent cluster weapon could achieve the same carnage.
A humorous weapon for sure, no one will predict where the next mine will go and it all comes down to luck when used. Good as a super weapon but has little or no tactical use.
