The UFO is a utility introduced in Worms Revolution. It can be used to move any Physics Object in the game to a location chosen by the user. It can also move Girders.
Description[]
The utility itself is a long range version of the Telekinesis, and is a better choice because the Telekinesis is very limited in range. When selected, a green UFO hovers over the selected Physics Object/Girder and picks it up, and you can move it to the desired location.
