After the monumental announcement that was the original StarCraft Remaster, Blizzard has officially made the original version of that game free to play today courtesy of a brand new update.
It all appears part of the big warmup before the release of StarCraft Remastered, which was announced by Blizzard last month. Apparently, that time is now.
When patching StarCraft, please use the "Run as Admin" option; it is required during your first client run to migrate saves and avoid issues from Windows system admin changes.
Blizzard Entertainment released Patch 1.18 for Starcraft and its Brood War expansion on Wednesday, April 19, making the classic real-time strategy game free for everyone to download and play on PC and Mac. But if you don't, or you're looking for some oldschool RTS action, the original game is available right now.
The game is now being remastered for release later this year and will include support for UHD resolutions, improved textures and localisation for eight additional languages.
There are some known issues, such as the profile section being inaccessible.
Update: Brood War version 1.18 has been released on the Battle.net forums for all regions now, not just the PTR server, and you can download it here.
Improved gameplay responsiveness during multiplayer by increasing turn rate to match LAN speeds over Battle.net.
