If you want to get a peek at the newest addition to the Overwatch lineup, you'll have to have to pop over to the StarCraft 2 World Championship Series website. And I mean the real StarCraft 2 WCS site, because Hana "D.Va" Song is, in game lore, a real StarCraft 2 pro. She's the best in the world, in fact, but she's taking a break from the game so she can serve her homeland.
"At the age of 16, D.Va became the #1 ranked player in the world and proceeded to go undefeated for the next three years in all competitions," her official StarCraft 2 player biography states. "D.Va is an international star, beloved by her fans at home and abroad, and has toured in exhibitions around the world. Recently, she has taken a step back from competition to focus on her commitment to protect the safety of her homeland."Because she's not yet listed on the Overwatch website, there's no indication as to what her abilities might be. Her affiliation is also hazy; she was described as "MEKA's newest recruit" on Twitter, but I don't know if that refers to a fictional StarCraft 2 team, or if it's related to Overwatch somehow. Either way, it's a pretty clever way to do tease a new character.
Tom has spent some time with the Overwatch closed beta and wrote a little bit about how fun its physics objects are here. Come for his words, stay for the lovely animated gifs. (Be sure to click 'em to see them in all their glory.)
