We've known that she's coming, just not that she'd be next.
Blizzard Entertainment has announced hero 32, Echo! In a one and a half minute video, Echo's story received some meat to its bone, revealing that she was the creation of Dr.Mina Liao, the scientist we had gotten to know through initial teasers for Echo.
An evolutionary robot programmed with a rapidly adapting artificial intelligence, Echo represents the cutting edge of technology.
GGRecon will update this article as soon as we find out more about Echo's class and abilities! It is likely that we will get a developer update this evening with Jeff Kaplan running us through her kit.
