Metroid: Zero Mission is set in 2130 when Pirates Space launched an attack on the Gen Research Center on the planet SR388. They stole a sample called Metroids – a virus that can invade any living organism and drain its energy, then take control of the mind. Moreover, they can be cloned very quickly under the influence of Beta rays, making it even more dangerous than before. If Pirates Space has a bad purpose in using Metroids, an epidemic of the destruction of the galaxy is inevitable. Now, the only way to prevent this disaster from happening is to rob the Metroids and kill the infected living creatures. Samus Aran has been assigned this task, he will leave for the planet SR388.
