Blizzard Entertainment announced plans to bring its forthcoming World of Warcraft title to Mac OS X at giant games-industry show, E3 yesterday.

Company president Mike Morhaime said Blizzard is dedicated to the Mac. "the Mac has always been a priority for us," he said.

The title is an massively multiplayer online gaming environment that is based on Warcraft. the company announced several new character classes, new forms of transportation and new lands at the show.

The company also previewed the game's new fully customizable interface, which allows players to adjust the appearance and features of the interface to suit their particular preferences and style of play.

Blizzard wants to expand the online multiplayer genre by creating a deep, immersive, user-friendly experience for both veteran and novice gamers. The action is set in the fantasy world of Azeroth, and features five playable races - Humans, Orcs, Tauren, Dwarves and Night Elves. More races will be announced when the game is released. The new title is peppered with features to interest gamers - new transportation types, magical items, weapons and armour.

New character classes include: mage, warrior, shaman, warlock, druid and hunter. These are augmented by a secondary skill system players can use to enhance their original abilities.

The World of Warcraft is divided into two continents, populated by monsters, with a variety of quests in which to engage. The game will be able to support about 3,000 players per server, using both Mac and Windows systems. The title's set to ship in the third quarter 2003.

The company also offered showgoers a preview at one of the single-player campaigns of the forthcoming Warcraft III: The Frozen Throne expansion set for Warcraft III. This title is scheduled to ship in summer.

The title returns players to the war-torn world of Azeroth, months after the defeat of Archimonde and the Burning Legion. The campaign follows the traitorous Death Knight Arthas and the renegade Night Elf Demon Hunter Illidan as they battle their way toward the mysterious Icecrown glacier in Northrend. Imprisoned within this icy tomb is the soul of Ner'zhul, the evil Lich King responsible for unleashing the Undead Scourge upon the world.

The fate of the world hangs in the balance once again.
