Story
The year is 3922 and humanity is colonizing the vast reaches of a wild and unknown space, known as the STELLAR INCOGNITA. You play the role of Sagacious-6, a nefarious and opportunistic clone worker that researches forbidden technologies for mind manipulation and corruption, in order to seek a life of indulgence and self-satisfaction. Set on a mission of revenge at the outset of the story, what fate awaits Sagacious-6 in the STELLAR INCOGNITA?
Game is complete!

+ I will begin work on "Stellar Incognita EX" in the coming months, which will be this entire game but with unfiltered artwork, updated soundtrack and 1000 extra images. Will include new characters and story branches that I had abandoned in the initial planning stage. Consider it a "Director's Cut".
+ Keep an eye out around September and October 2024 for the start of my new fantasy Ren'Py game, HEROES OF CELTICA!

A dozen short, badly written mind-control sci-fi plots crammed into a single Ren'Py porno. Overly verbose, while simultaneously skimming over most of the interesting bits. Feels like reading a rushed summary of an actual sci-fi story; lots of proper nouns…
