No, the game is not abandoned.out of the loop..
hmm is this game abandoned? update date still in 2021??
The game artist hurt their hand due to overwork (the same thing that happened to the previous one, funnily enough) so Zion paused the game and worked on Eden Crest in the meantime.
Eden Crest was released eight months ago and Zion resumed work on Succubus Covenant, but real life issues delayed him. Work is still ongoing, though.
