Challenges

[M4573RxB0x]

I've got up to challenge 16 as of last night (I think) and failed at it like 4 times and couldn't be bothered at it for a 5th time (I might continue today though).

I was wondering if anyone has made video guides for the levels. I know a lot of people say concentrate on defence and wait for sudden death, but I don't know how to concentrate on defence. I don't see how you can defend on Worms.

If anyone can link me to a good video guide. I would be very thankful.
