Blizzard always rolls their expansions out with style, and "Wrath of the Lich King," the latest add-on to MMORPG World of Warcraft, is no exception. The Lich is making his appearance in Azeroth with a worldwide zombie invasion!

Blizzard seems to be rolling out the event on a few U.S. servers so far. We've put the details under the cut because there are SPOILERS!!! aplenty.

Like all good zombie invasions, this one starts small, with a few infected zombies wandering about the countryside and some infected crates in Booty Bay. If you loot the wrong box or are damaged by a zombie: Wham, you're undead. Here's the rest of the details, from mmo-champion.com:

• Zombies will randomly spawn in the world (and near cities) and infect anyone they damage.
• People infected by zombies can either get cured by other players or by Argent Healers deployed in most of the zones.
• If a player or NPC isn't cured within 10 minutes ... He will turn into a zombie !
• Players changed into zombies have access to a new set of skills to let them attack and infect other players. They become friendly with other zombies and hostile to all player factions. Also ...
• Don't waste your time finding and creating a level 1 on this server, being hostile with all player factions also means that guards will kill you on sight and pretty much instantly in the case of a level 1 character.
• This is probably just the first part of the world event, it doesn't look fully deployed at all.

The expansion will be released on November 13th.
