Overwatch’s new gravity-controlling tank Sigma is what the game needs

Overwatch has released its 31st hero into its public test realm, so anyone who downloads the test version of the game can give the new character, Sigma, a try.

Sigma is a tank, meaning that he’s a character who excels at protection. Tanks usually come in two flavors. Main tanks focus on shields and defensive abilities. They’re good at protecting the whole team. Then you have “off tanks” that are beefy characters with high amounts of health and defensive abilities. They aren’t as good at protecting teammates, but they can operate on their own and deal a lot of damage to the enemy without dying.
