Blizzard today announced that StarCraft 2 is receiving a free campaign to act as a prologue to the Legacy of the Void expansion. The campaign, Whispers of Oblivion, will be free to all players regardless of whether they own or have played any previous Star Craft titles.

The campaign bridges the first expansion, Heart of the Swarm, and Legacy of the void, also serving as an introduction to catch new players up on the lore or the world.

A beta version of the campaign will be available in July to people who pre-order Legacy of the Void, with an open release to launch later.
