Blizzard dropped a massive announcement during Blizzcon 2017. Starcraft II will be going free to play for everyone on 14 November; which should be closer to 15 November here in Malaysia. This new structure includes a majority of the multiplayer content, and the first single player campaign.
The Wings of Liberty campaign will be made free for everyone after the middle of November. Players who already own Wings of Liberty will instead be given the Heart of the Swarm campaign to enjoy. That said, those who own the first two campaigns but skipped out on the third Protoss focused Legacy of the Void are out of luck.
All campaigns, including the standalone Nova Covert Ops, will be on sale on the Blizzard store.
Unranked multiplayer is also available, and those who complete 10 First Wins of the Day will permanently unlock ranked multiplayer. Thankfully, this can also be done against an AI opponent. Finally, Co-op Commander mode is being made available. That said, free players will only be able to reach level five without giving some money to Blizzard.
Loyal Starcraft II players who already own all three campaigns will be receiving an exclusive Ghost skin and three new portraits. It’s not much, but perhaps a small token of appreciation for having stuck with the franchise for so long.
Blizzard will still be monetising Starcraft II with DLC like announcer packs and skins; which means there’s still some content on the way for fans of the game. If anything this only means that both the original Starcraft and its sequel are now available for everyone to play for free.
