If you got brood war then this is a good thing for you. Build alot od Lurkers and put the in the overloads. You must do this fast or you got no chance at this when they are in the overload go to the enemy base and drop them at the enemy minreals place and put them under ground and hope for the best.

CreepColony's Opinion: This won't work well against map hackers, because I tried it before! Also, if you are playing against someone good who puts defense near their minerals, this will not work either.
