Blizzard continues to update the beta build of StarCraft II with new patches. Late on Wednesday the eighth patch for the beta to the long awaited RTS sequel was released and as usual it was mostly about unit balance changes. Build times for the Terran Thor and Siege Tank units have decreased and the Protoss Void Ray has had a number of changes.

In related news, Blizzard is using its official StarCraft Facebook pages to randomly give away beta codes for StarCraft II. Simply check in to the pages (one for US, Canadian and New Zealand residents and the other for Latin American residents) and when a beta code shows up randomly you just have to be the first to redeem it on the Battle.net web site.
