About

The Exploration Vessel Atlas is crewed almost entirely by women, sent out to find some way of keeping humanity going. What none of them notice is that something else got on board looking to do the exact same thing for its own species.

Buried among the crew, an alien larva bides its time, and the ship becomes the setting for its slow, quiet takeover. The game leans on that setup directly: infiltration and transformation rather than open war, with the horror coming from how ordinary everything looks until it isn't.

Play moves between exploring the ship's sandbox areas and working through puzzle sequences that gate progress, with an RPG layer underneath tracking the crew's condition as the larva's influence spreads. Encounters push toward mind control and forced scenarios rather than player choice, told through 2D character art and animated scenes rendered from an internal view. It's still in active development, so expect rough edges and the occasional bug alongside the alien.

Changelog
