Diablo II will boast a far greater scope than Diablo. This time, you're questing to save an entire world, not just a town. Each of Diablo II's four towns will have one main dungeon, several subdungeons, and a surrounding wilderness area that can be fully explored. And, according to co-designer Eric Schaefer, each town will have as much gameplay as all of Diablo.
Towns will be arrayed in linear fashion, meaning that you'll have to finish one town before you can move on to the next. But, once you finish clearing a town, you can return to it later. Certain quests will span several towns, requiring you to travel back and forth, probably by caravan or teleport.
Although Blizzard is being coy about the three other towns, it will say that each has a unique flavor and environment. One act will take place in the desert, possibly in a Horadrim town, with a few resident sorcerers. Another act will take place in a jungle environment.
Each town will also have a powerful end boss. Andariel will be the main villain in the monastery town and Diablo will be the final boss, but who are the other two? Blizzard wants that to be a surprise.

Fantastic Five

Like the settings, the character classes will be more diverse this time around. There will now be five classes - two spell-casters, two fighters, and one hybrid - and each will play differently. The attributes list will stay the same, but combat will change. While spell-casters will have a melee weapon and a range of spells, fighters will have a repertoire of fighting moves that will rival the mage spells for diversity. These moves will, in effect, replace spells for these melee characters. (The fighters will be able to cast a few spells, but only through the use of scrolls or staves.) The hybrid class should have a mix of spells and fighting moves.
By giving each class a wide range of fighting abilities and spells that no other class can use, Blizzard hopes to make the playing experience for each character different. Each class will also be customizable, because not every player will be able to master the fighting moves of every class. Two players could thus create characters of the same class but with very different fighting abilities.
Diablo II will also boast a host of new spells and monsters. Only a few monsters from Diablo will be back, and each town will have its own mix of monsters.

Building Character There are no rogues, warriors, or sorcerers to play in Diablo II. The Lord of Terror is mightier than ever, and the previous game's heroes simply aren't up to the challenge. So Blizzard has created five new character classes. One, the Amazon, is a cross between the rogue and warrior, with superior melee and range attacks. Her main attacks make use of either the bow or spear. She will have five levels of abilities, each more powerful than the last. You can see some of the proposed abilities in the chart. These aren't all of her abilities, and in fact, she won't be able to learn all of them. You'll have to pick from among the total number, meaning that gamers will be able to customize unique characters. You might specialize in the spear, while your friend specializes in the bow Level Skill Effect 1 Vital shot (bow) Slower, but more damaging shot   Jab (spear) Faster, but slightly less powerful attack 2 True aim (bow) More accurate, but slower shot   Entangle (spear) Temporarily paralyzes target 3 Safe shot (bow) Fire into melee without hitting friends   Fend (spear) Less accurate hit, knocks target back 4 Dodge Instantly dodge an attack   Impale (spear) Triple damage, but chance of destroying spear
