"The Inquisitor III" is a full-fledged RPG based on GZDoom engine. There are no defined classes. You can develop your character in different directions, creating your own class as a result. You can get in the way of the warrior, battle mage, priest (i.e. mage, specializing mainly in defensive spells) or a combination of these ways in different proportions. We have our own dialogue system for which you have to setup two additional buttons in the menu: one - to switch between anwers, the other - to use the selected one. These buttons are also used to select and cast defensive spells. Compared with "The Inquisitor II", the set of weapons and monsters is significantly expanded. New spells and items in the inventory are also available. There are 12 large maps combined into one hub.
