Blizzard is keen to push StarCraft, they have remastered the original, made the original version free, and now StarCraft 2 will also be free.
On 14 November, the Wings of Liberty single-player campaign and every Co-op Commander will be available to everyone for free. All competitive multiplayer content will also be unlocked for free. Heart of the Swarm, Legacy of the Void, and Nova Covert Ops will be available for  $14.99 or as a bundle for $39.99 if free players want to continue the story. Future Co-op Commanders will also be released for free until they reach level 5.
Bizzard released a list of everything that will be available for no cost.
- The original Wings of Liberty campaign. Experience the original epic campaign that kicked off the StarCraft II saga! If you picked up Wings of Liberty previously but haven’t come back to StarCraft II in a while, we’ve got good news for you too—if you already own Wings of Liberty, you’ll receive the second installment in StarCraft II’s campaign, the zerg-focused Heart of the Swarm, for free. Make sure to log in between November 8 and December 8 to claim it.
- You will be able to access the ranked multiplayer ladder to compete with other players to become the best of the best, complete with all of the multiplayer units from Wings of Liberty, Heart of the Swarm, and Legacy of the Void. All you have to do to unlock it permanently is earn 10 First Wins of the Day in Unranked or Versus A.I. play—our way to preserve the quality and integrity of the ranked experience.
- Current and upcoming Co-op Commanders are available to play for free up to level five, and the level restriction for weekly mutations has been removed. You’ll be able to tackle these extra challenging missions with your friends right away. The Co-op Commanders Raynor, Kerrigan, andArtanis will remain completely free, meaning that you can keep leveling them to your heart’s content.
Anyone who has purchased any of the three campaigns will also be sent an email from Blizzard to say thanks and they will be handing out an “exclusive” Ghost skin as well as three new portraits.
