Jeff from the Overwatch team has delivered another developer update, this time delving into the abilities of the game's new character Sigma. So, Siebren de Kuiper, a.k.a. Sigma, is a barrier tank that should be great for clearing chokes.
Unable to control his powers or his mind for that matter, De Kuiper was hospitalised under the codename Sigma. Eventually, Talon learned of him and broke him out, using him for their nefarious purposes, even though Sigma is said to be unaware he's being used.
Enough with the stories - it's time for Sigma's abilities, the first of which are Hyperspheres, his regular attack. "Sigma launches two gravitic charges, which bounce off walls and implode after a short duration, damaging enemies within a sizable radius", Blizzard wrote.
There's also a slight gravitic pull and thanks to their bounciness, Hyperspheres will allow for bouncing shots behind corners or quickly slipping them under Reinhardt's barrier when you find the opening.
Sigma wields the Experimental Barrier that can be used to clear chokes, much like Reinhardt or Orisa. However, he can also send his barrier at other players at an angle, which can, for instance, cause Pharah to kill herself with her ult's splash damage if you time it right.
Kinetic Grasp is Sigma's defensive ability, where he absorbs up to 400 of incoming damage and transforms it into protective shields. Jeff mentioned that the number is likely to be tweaked, but the Public Test Realm version currently uses 400.
Accretion allows Sigma to form a rock out of thin air and although you'll hear and see it coming from a mile away, if you don't, get ready for a ton of damage.
Last but not least is Gravitic Flux, the ultimate ability of Overwatch's new hero. It allows Sigma to take to the skies and lift enemies in a large area, only to slam them into the ground, taking about half of the characters' health.
