There are a lot of cool little gimmicks on worms 3D, for example on the computer mission, on the computer keyboard, simply make your worm jump on to the letters: T-E-A-M-1-7
You dont need to include the dashs, this unlocks somthing i cant remember what.
Also on the schools in for summer mission, throw a grenade through each basketball hoop to unlock extra bonus missions and stuff i dont know what. Dont worry if u are no michael jordan either, you can simply go stand underneath the hoop and through one full pelt into the sky above you, so you can shoot the grenade up through it. Pretty cool, huh???
