Hey guys, first messege XD
Anyways, It was about 2 years ago I think when I played this game at a friend's house, and I remember that he had all the super weapons, Mail Strike and MB Bomb and many more, But whne I play it on my computer, I never saw these weapons, How can I get those?

Thanks in advance.

In Worms World Party there is a Weapon Scheme called "The Full Wormage".
Unlike W:A, it is unlocked from the very start. Just choose this scheme and you are ready to go!

It worked, but it seems like it only works on Multi-Player mode, thanks though ^^
