Project Solaris

Project Solaris is a roguelite RPG by Greenhorn and IndieArk. The failed mage Solaris has 100 days to prepare, together with the homunculus Hom, for a decisive exam.

The game combines day planning, turn-based combat, QTEs, equipment, relationships and multiple endings.

Project Solaris was released on Sep 21, 2026 on Steam. The developer announcement gives 11:00 JST as the official launch time.

Currently only PC via Steam is confirmed. No other platforms have been announced.

Each of the 100 days begins with three action cards. Depending on your choice, Solaris fights, earns money, learns skills, rests or deepens relationships. These decisions affect the exam, side stories and possible endings.

In combat, Solaris gives Hom commands. QTEs affect how difficult actions are executed; a higher trust level makes strong abilities easier to use.

As a minimum, Steam lists Windows 10, an Intel Core i7, 16 GB RAM and 16 GB of free storage.

Money from fights and shop work goes into equipment. Solaris gets rather expensive, powerful items; Hom can combine several cheaper, randomly available pieces of equipment. This changes the optimal build depending on the skills you have learned.

Certain cards and milestones open side stories. Relationships with characters such as Tetia, Croisé, August and Melchior change the course; the sum of your decisions determines which ending you reach.
