Blizzard is gearing up to release a remastered edition of the original StarCraft. And in preparation for that big release later this year, they've released the original for free.

StarCraft®: Remastered upgrades the essential sci-fi strategy experience from beginning to end. Welcome back to the original game and its award-winning expansion, StarCraft: Brood War.
We’ve remastered our units, buildings, and environments, improved game audio, and broadened our supported resolutions. Illustrated interludes bring the struggles and victories of heroes like Artanis, Fenix, Tassadar, Raynor and Kerrigan to life like never before. Most importantly, the strategy gameplay that StarCraft perfected years ago remains unchanged.
Get ready for Remastered. The original StarCraft is free to download right now!
