Twenty years have passed since the Bugs 2 tragedy, and it's now 2619. Mars has been transformed into an Earth-like star due to the "Terraforming Project" carried out by humans, but on the other hand, an encounter with a mysterious evolutionary creature "Terraformer" and a pathogen "Alien Engine Virus" with a 100% mortality rate have emerged. To end this nightmare, a crew whose human bodies have been strengthened by special surgery is sent to Mars.

We can feel that we are being watched, and to top it all off, night is already falling. "Hello? Can you hear me? Hello? Damn it!" Michelle throws the intercom on the ground.
