The animated shorts are aimed to connect new players with the World of Warcraft's enormous lore. Blizzard plans to have a similar approach that we saw in Warlords of Draenor. Sadly, we won't see any standalone, full cinematics. For now, they will remain unique to Overwatch.
The first episode is expected to arrive soon. Rumors are, the episode will highlight a high elf who joined Illidan’s Demon Watchers. We will see how this zealot will start questioning the movement and its ideas.
