Alien Invasyndrome Demo - 1.0 (English, Japanese)

The exploration vessel Atlas drifts through deep space with its all-female crew, completely unaware that Alien Invasyndrome has already begun its silent takeover from within. Playing as the parasitic alien larva hiding among the humans, you’re tasked with one primal goal — ensure your species’ survival by any means necessary, even if it means turning the crew into unwilling hosts.

Such kind hides in the crowd on the ship, an <Alien Larva> from a distant planet. < This game is under active development, expect bugs happening and feel free to report. > Tied to the fate of its bloodline, it uses every way possible to grasp the faint hope. Rooting on this vessel, turning these females into breeding beds. To survive, this is its only way. It's only another typical day on < Atlas >, another "normal" day.
