It was meant to be a rescue mission. One of our interstellar launches that NASA lost all contact with ten years ago finally reentered Earth’s orbit. Astonishingly, the ship still registered human life signs so an astronaut medical team crew was hastily assembled and a billionaire’s self-funded rocket commandeered to expedite the the rescue attempt.
For a mission done on the fly, everything surprisingly went to plan…until the rescue team discovered the zombified bodies of the interstellar crew connected to a bizarre life support system that kept their human hearts beating within their necrotic corpses.
The rescue mission commander immediately called for an evacuation but as the team prepared to leave, extraterrestrial lifeforms came out of stealth mode, closed in fast, and trapped them. The alien intruders forced their way into the humans’ brains, using a primitive mental pictogram code in order to establish a crude hive mind to learn everything they could about Earth’s defenses and their probability of survival in the war that was about to begin.
