StarCraft II: Legacy Of The Void To Get Free Three-Mission Prologue Series Whispers of Oblivion

Blizzard has announced a three mission prologue series that will bridge the gap between two StarCraft II expansions. The missions, called Whispers of Oblivion, will fill in story details between Heart of the Swarm and the upcoming Legacy of the Void expansion pack. The prologue series also marks the first time a mission has followed the story of Zeratul since the first StarCraft II expansion, Wings of Liberty.

The missions will be free to all players, but pre-ordering the expansion will grant early access to the content.
