On 12th December as part of Game Update 5.6.1 Bioware is releasing a brand new 8v8 warzone. It is located on Yavin 4 and features Alderaan-styled objectives with giant firing turrets for each faction and a designated area in the middle, where the usual bundles are expected to happen.
I now have a dedicated Guide to the new Yavin 4 Warzone! Check it out!
Check out the very first screenshots that the developers published today! Maybe a trailer tomorrow, who knows :)
