Acaratus crosses the Middle Ages and steampunk together. In this world, humanoid robots exist alongside slavery. The lands are ruled by an emperor named Helios. One day, this despot is challenged by a girl who calls herself Adina. Previously, she was a slave trader, but now she is engaged in the liberation of people and leads the revolution.
The project belongs to the genre of turn-based role-playing games. There are also elements of bagels and CCG. The user controls the combat mech. He can replace parts, including limbs and cockpit. There is an opportunity to change weapons. For example, you can give the robot a gun in one hand, and a shield in the other. In Acaratus, all these parts are bought in stores, given out as a reward or knocked out of defeated rivals.
Battles take place in open and closed locations with an isometric view. Gradually, the user will acquire a small army of mechanical warriors. They move in squares. Enemies can be attacked from a distance or hit close. Mechs can also use skills like repair and dash. To do this, you need to use cards from a deck pre-assembled before the start of the fight. The character gains experience for participating in fights and is pumped. Between fights, the heroine travels around the global map (it is generated randomly) and participates in random events.
