Zak McKracken and the Alien Mindbenders

After finding a strange crystal, Zak manages to get the help of the anthropologist Annie and her friends, Melissa and Leslie. The four unlikely heroes must now figure out a way to destroy the dumbifying devices and save the Earth. Zak McKracken and the Alien Mindbenders is a third-person puzzle-solving adventure similar in gameplay to Maniac Mansion. The player chooses verb commands (Open, Pick Up, Give, etc.; there are no Look or Talk commands) to interact with the game world. The game features up to four controllable protagonists; it is possible to switch between them at any time after they have been introduced, and also exchange inventory items if the characters are in the same location. The game can be described as a "globe-trotting" adventure, since the heroes are required to travel to different exotic countries and even leave the Earth for a while in order to complete it. Some of the puzzles are optional or can be solved in different ways.
