During his annual address to the community at BlizzCon, Mike Morhaime, the president of Blizzard Entertainment, announced that large portions of the real-time strategy game would be made available free of charge. Unlocking play in Ranked Mode will require you to earn 10 First Wins of the Day in either of the two modes that are already available to you. Several challenge-mode mini-games will also be included, with focused goals created to ease players into the basics of multiplayer strategies.
On the multiplayer side, new players will immediately be able to take part in the Unranked and Versus A.I. modes using the full set of StarCraft 2 units. Blizzard is a household name for most PC gamers with StarCraft II, Diablo 3, World of Warcraft, Heroes of the Storm, and Overwatch all topping "hours played" charts for millions of gamers both casually and competitively around the world. A move that could, perhaps, bring a new wave of interest to the classic series. The original Wings of Liberty single-player campaign and every Co-op Commander will be accessible for free.
In addition, players will gain free access to Kerrigan, Raynor, and Artanis Co-Op Commanders completely for free.
The award-winning StarCraft II: Wings of Liberty story campaign is free in its entirety. This free-to-play change will likely be the most significant step in preserving StarCraft 2's relevance yet. Make sure to log in between November 8 and December 8 to claim it. All other Commanders will also be free up to level five.
Blizzard has done similar promotions before, including multiple free weekends of play for their popular first person shooter Overwatch. If you purchased any of the three campaigns as of October 31, you'll get an exclusive Ghost skin.
