Blizzard just officially revealed their latest Overwatch Hero addition today. The new character is named Echo and is "an evolutionary robot programmed with a rapidly adapting artificial intelligence." This character has a name and an origin story and not much else.
Blizzard says that Echo is "coming soon" to the game. This presumably means it will be coming first to public testing and then to the general public, as these things tend to go. Hey, enjoy this here origin story trailer for Echo. Maybe it'll get you interested in playing Overwatch again. Or maybe you'll just be reminded about Blizzard's recent business practices such as how they bowed to China, asking if you own a cellphone, Diablo IV apparently being always online, or maybe the dreadful Warcraft III Reforged release. You know, whichever. It's a toss-up at this point.
