Callisto-X [v1.0] [ProfessorX-10]

December 23, 2024F95

Overview:
Callisto-X is an unofficial fan created version of Xavster_Gaming’s Callisto, enhanced , expanded with a twist.

Callisto-X offers an enhanced, more interactive, adult Sci-Fi Adventure Novel/game based solidly on the original but with many subtle changes and a new ending. For those who prefer a straight VN a walk through option has been added to help although one sand box area remains.

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 crew members–not all of whom like you or trust you. But then fate unexpectedly casts you into the role of Galactic defender against an onslaught 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?

Developer Notes:

I think it’s a better game. If you agree at all, buy me a coffee. Thank you.

WALK THROUGH OPTION NOTE: Normally OFF, Set “ON” in Preferences. If NO green option text shows, either is ok.

Note that in the fighter battle, the GREEN TEXT indicator comes on in the NEXT scene AFTER you chose the correct option.

As a final word, this release presents the reason I decided to modify this VN’s story in the first place. It serves as my vision of this spectacular galactic adventure and a better way it could have ended.

Finally, one appreciative, humble thanks to Xavster_Gaming for his sympathy and moral support for this amateur Dev with the temerity to modify his already completed masterpiece.
