We’re planning to implement StarCraft II Patch 2.1 next week. This patch includes more levels and new rewards, new changes to Clans and Groups, a 100% free Arcade, remastered Classic StarCraft and StarCraft: Brood War music, adjustments to the league distribution percentages on the ladder, Extension Mods, and many other features.
Our plan is to release the patch in each region as quickly as we can over three days:
Tuesday, Jan 21 – Americas, Europe
Wednesday, Jan 22 – Korea and Taiwan, China
Thursday, Jan 23 – Southeast Asia and Oceania
Please note that the release day for Patch 2.1 in Southeast Asia and Oceania is taking place on Thursday rather than Monday (we’ve often released patches in this region on Mondays). This is a one-time adjustment for Patch 2.1. With future releases, we’ll return to patching this region on Mondays as before.
As always, the above dates are subject to change should an issue arise between now and then.
Global Play
We’ve built the game so that it should install the new patch for you when you launch the game, based on the region you last connected to. When you try to connect to a region that is running a newer version of the game than what you are in, you will be asked whether you want to patch so that you can play on that region.
If you agree, the game will restart and install the new version. However, you will then be unable to play on any region that has not yet updated to the latest patch. If you update and then try to play on a region that is not yet updated, you’ll receive an error.
