World of Warcraft is setting a whole new story arc in motion with its next expansion, The War Within. If you can’t quite wait until this summer to see what the first chapter of the new Worldsoul Saga trilogy has to offer, you might not have to wait so long. Blizzard are running a beta for War Within that will give testers the chance to delve into the subterranean addition early – and sign-ups are now open.
