PopCap has released an impressive Peggle add-on for World of Warcraft.
The game, once installed, can be called up by typing "/peggle". There are WOW-themed backgrounds, and points are awarded for use in a special Peggle talent tree. Abilities here improve critical hit chance, modify styles scores and so on.
World of Warcraft players can challenge each other to Peggle Duels, or rope their entire friends list into one enormous Battle, which can be customised to have a time limit or shot limit.
Furthermore, if cast as Loot Master, players can use the "/peggleloot" command to make their raid or group play a one-shot Peggle challenge to decide who gets the item, instead of relying on "/roll".
Peggle joins fellow PopCap favourite Bejeweled as a WOW add-on, and both can be downloaded from the PopCap website now.
