World of Warcraft Battle Chest (new with Lich King) for PC... The challenge rings in your ear. It gnaws at your stomach. It summons your muscles to action. It's the World of Warcraft. The MMORPG that took gamers across the world by storm is back as part of a feature-packed Battle Chest collection - and it's just begging to be unlocked. Mere mortal, it's time to throw caution to the wind, leave the mundane realms of Earth behind and depart for the dangerous, mythical lands that await in the World of Warcraft.
