Your base is one of the few safe islets left on Earth after a global invasion from space. The nightmarish creatures who consider themselves to be the highest race arrived on our planet and began the systematic destruction of earthlings. In addition to physical impact, they released a virus that turned many people into the same monsters as the aggressors themselves. Mutated people mixed with aliens will try to penetrate the fences. You must meet and repel the attacks, no matter how many. Kill the maximum of enemies and enter the game history as the killer of monsters.
