World of Warcraft – Psst…There IS No Secret Cow Level….But There IS!

World of Warcraft players are getting a wee taste of Tristram as part of the 20th anniversary celebration for Diablo. In a limited time series of events, players can gain an achievement, take on Treasure Goblins all over the Broken Isles, and even head to the “Secret” Cow Level to try and butcher the Cow King himself.
