Arx Fatalis

Arx is a first-person, 3D RPG in the vein of Ultima Underworld. You explore a large underground, medieval, fantasy organization inhabited by both monsters and conversive non-player characters. Your character will increase in skill and attributes as they level up and many different weapons, armor, and items will be available to equip them. You will be able to cast over fifty spells using a rune-based system. A few of the technical details include highly detailed, mesh-based monsters in 32-bit, real-time physics, breakable items, dynamic lighting and excellent artificial intelligence provided by a scripting language.
