LV-426 is a faux three dimensional game that you will enjoy playing if you like the story of Aliens, especially, as the game is based on the movies, despite the fact that the story has been rebuilt in order to create a unique game. The monsters are similar to what you have seen in the movies.
LV-426 is a planet that you will have to investigate in order to find out what ever happened to the mining workers that were located there, as they are not answering any radio call at all, and the situation that you will encounter was nothing that you would have expected.
