[Update]: Overwatch's newest main tank Sigma has now arrived alongside the long-awaited Role Queue!

These are certainly exciting times for Overwatch. Not only has Blizzard recently added replays, workshop modding tools and a whole bunch of balance changes, but they are getting ready to also introduce 2/2/2 locked Role Queue and even a brand new hero!

The hero in question is Sigma, a highly skill-based tank with a quickly deployable shield and an ultimate that lifts enemies into the air for a few seconds, only to then slam them into the floor for 50% of their max health. A devastating move, though thankfully Sigma doesn't seem to charge it all that frequently.

You can learn more about Sigma himself, as well as what series of events led to his powers, through the recently posted origin trailer. Have a gander, it's one of the best Blizzard has released so far:

On the other hand, if you're interested in learning all of the details about Sigma's abilities, as well as more about his lore, you should head on over to the official website. If you prefer a more hands-on approach, however, I'm sure you'll also be glad to hear that Sigma is currently available on the PTR alongside the upcoming Role Queue!

Have fun, he really is an interesting hero!
