Starcraft 2 includes all the Starcraft 2 packages you need to get along with the Battle Chest product line. When you buy Starcraft 2 Battle Chest, you are downloading 3 different packages as a single code. When you upload, you have installed Starcraft 2 Wings of Liberty, Starcraft 2, Starcraft 2 Hearth of the Swarm and Starcraft 2 Void of Legacy. Instead of buying three packs separately, you buy 50% more for the Battle Chest. You can click on the packages below to see the individual information of the packages.
