Tactical combat system, including standard attacks, aimed attacks targeting specific body parts, and per-weapon special attacks such as Whirlwind and Impale.
Detailed crafting and alchemy systems: forge your own weapons, brew potions and poisons, experiment with Liquid Fire and Black Powder.
8 weapon types: Daggers, Swords, Axes, Hammers, Spears, Bows, Crossbows, and Throwing Weapons, each with its own advantages and disadvantages.
Fully customizable main character, as well as 10 possible companions, not all of them human (maximum party size is 4).
50 challenging fights and 4 different endings
