In addition to fighting demons, you can also take on additional quests from villagers scattered accross the map.
The game plays in four acts, one act in each major town. Each town faces destruction by a powerful evil force, which you must destroy. You must fight all of these evils in each major town before you can face Diablo, the ultimate evil. The second game in the Diablo series is a major improvement over its predecesor. The game is four times longer than the original, with two new character classes, 3-D graphics, day/night cycles, weather effects, and a ton more weapons, armor, items, and spells.
