Mission to Planet X

Mission to Planet X is an educational adventure game that teaches the player how to use the Internet (or at least as it was in 1996). The player is contacted by an astronaut who is stranded on Planet X. The astronaut explains that Planet X appeared in our solar system suddenly and was found to contain intelligent life. When the astronaut, as a representative of the Earth, contacted them, they pretended to be friendly but in fact planned to invade Earth. The astronaut managed to stop their plans somehow but is now stranded on Planet X. The player needs to travel to each of the other planets in the solar system and solve puzzles that require Internet proficiency in order to collect 8 objects that are required to save the stranded astronaut.
