Overview:
Through the deep space of thousands of stars,
Exploration Vessel <Atlas> advances steadily.
With a carefully chosen crew of female, they seek for a way to continue the bloodline of humanity.
However, little do they know...
hidden in the silent shadow of the cosmos, another kind also strives to pass on.
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.
In this game, you play as the Alien. Weak in the beginning, you should utilize your
stealth ability to sabotage and grow, eventually dominating the ship.
