Five years after humanity’s first encounter with the Remo—a ruthless, vampiric alien race—only one survivor remains: the mercenary Hangman, a human-Remo hybrid. When scientists aboard Spectare Station begin researching these deadly creatures, the station comes under a sudden, brutal attack. With no one else able to respond, Hangman is called in to drive off the invaders and save the besieged researchers.

As Hangman, you must navigate the station, locate the scientists, and evacuate them to safety. Survival is a delicate balance: your hybrid nature drains your blood over time, and replenishing it is essential. Harvest Remo blood for maximum advantage—or use human blood if you’re desperate. Combat is visceral and inventive: weaken enemies, then rip off a Remo’s arm to use it as your own, unleashing devastating attacks.

With intuitive controls and fast-paced gameplay, Call Sign Hangman blends action, strategy, and dark sci-fi horror. Every decision matters, from who you save to whose blood you harvest, as you fight to survive the nightmarish invasion.
