Worms Revolution

On Training 4: Physics Objects there are plenty of objects for you to destroy. A Poison one, Water, Explosive, a Dust and a Fire one. Just make sure that on the mission you turn around and Bazooka the Yellow lamp. If you have done both campaign and puzzle missions you will most likely have this by now, if not go to Versus and keep blowing up physics objects in each game; the DLC objects are not required towards this amount.
