Thymesia is a dark action game developed by OverBorder Studio for the Nintendo Switch platform. The game is set in a kingdom that is in chaos after a failed attempt to stop the use of alchemy. The streets are infested with monsters, and the only way to survive is to harness the disease from gruesome bosses and wield them as weapons.

In Thymesia, you play as Corvus, who has lost his memory, and the key to understanding the chaos lies in his memories. You must recover his memories through different adventures, and with different choices you make and items you collect, you get different endings. The game also allows you to shift into your raven form during battle, upgrade and modify your basic movements and plague weapons, and build your own play-style to prepare for the challenges ahead.
