Worms 2: Armageddon

This does not need to be done in one turn, but must be done with the same worm. If the worm dies, then you'll have to start over with another one, so make sure that it is suitably protected after you have collected a few crates. I would recommend a similar strategy as mentioned in "Happy Shopper" for this one. An underground map on Crazy Crates is your best bet for this - remember that Ninja Rope is your friend here. Make sure that the round progresses a little before going for this, as there will be many more crates on the field, thus making it a little easier.
