Callisto-X is an unofficial fan created major expansion and enhancement of Xavster_Gaming’s original Callisto.

Callisto-X offers an altered, more interactive, adult Sci-Fi Adventure story/game with surprises, mini-games and a new ending among the several existing ones, all of which are determined by your personal choices and fighting skills. You play the role of a former military officer, trying to make a living as a free-lance interstellar trader and scavenger in the vastness of space aided by group of exotic & talented women crewmembers–not all of whom like you or trust you. But then fate unexpectedly casts you into the role of defending yourself and innocent millions against an onslaught of an overwhelming hoard of ravenous, life destroying aliens led by an evil, powerful queen.

Will you save the Galaxy? Or will you DIE in the attempt?
Will you retire a happy Hero? . . . or be just another dead body floating in space?​
