Caves of Qud is a roguelike game with an unusual mix of styles, such as: fantasy (ordinary swords and bows as murder weapons, combined with magic and wondrous creatures), post-apocalypse and science fiction. A special feature will be the choice of the protagonist before the start of each new save with their bonuses. The mutant gets unlimited space for various modifications, by receiving changes in his DNA, in other words, mutations, among which there is a second heart, a second head, wings, claws and much more. An ordinary person is more mobile, has a larger supply of pumping points for various attributes and a good initial set of armor, which makes the start of the game for a human representative easier.
