This new episode can be played without knowing the previous games, the necessary story elements being brought through the narration - but of course knowing the other episodes will enrich your experience.

"You are an astronaut from planet Terra who has been invited to the Table of the TSP - Terran Space Pirates, because one of the members, also your friend, is missing. Your mission is to go to the Catyph planetary system to use the Kunci, a kind of stargate, which will teleport you to the last presumed location of your friend. She was looking for a rare Black Cube, an alien artefact with various powers. After using the kunci, you realize that you have to explore an old Anterran space station, but you are stuck there with no way to go back. In addition you can't find your friend, and you feel that a hostile presence is looking at every one of your actions in this dark place..."

Zly.ii was made with the Unity engine, using 360° spherical views (pre rendered backgrounds and video cutscenes, like in Myst III and IV). It has the very usual ASA art style, quite simple with a retro sci-fi vibe. The logical puzzles are in the continuation of the Black Cube classics, requiring you to explore, observe, understand and take notes with paper and pen.

The gameplay is quite simple and uses the mouse. Keyboard is sometimes necessary to input passwords/commands, or to display the menu (echap).

The final HD Edition will be released somewhere in the end of August or beginning of September 2024 on both itchio and Gamejolt, in English and French.
