UFI und sein gefährlicher Einsatz, known as E.T. Go Home in the United States, is a 1983 video game created for the Atari 2600 that is loosely based on the 1982 film E.T. the Extra-Terrestrial. It was created in Europe. Copies of the game are very rare, and most copies still have the typo of the title, which reads, E.T. Go Come. The cover shows E.T. standing near a parade of anthropomorphic jelly sandwiches, balloons, trees, and chicken nuggets. None of these creatures ever appear in the game. It is the European version of a game called Alien's Return.
Taking control of E.T., your mission is to find parts of scrap metal to build a spaceship to send you back to your home planet. You must avoid evil alien kidnappers who have been sent to destroy you. The game has a resemblance to its fellow Atari 2600 games, Pac-Man and E.T. the Extra-Terrestrial.
