Tips and How to Play

Bounce Hyperspheres Around Corners

Sigma's Hyperspheres can bounce off most solid objects before imploding. Use this unique trait to your advantage by bouncing them around corners and other odd angles to take foes out of your line of sight by surprise.

Reposition Experimental Barrier Often

Properly managing your Experimental Barrier is vital for playing Sigma effectively. Frequently reposition your Experimental Barrier to efficiently cover your allies and smother attacking foes.

In addition, remember to let Experimental Barrier regenerate by recalling it whenever you and your team are behind natural cover and do not need added protection.

Interrupt Abilities with Accretion

While Accretion is effective at knocking down key enemy targets for your team, remember that it can also interrupt abilities with its stun. Use Accretion to disrupt channeled abilities and ultimates like Pharah's Barrage and Moira's Coalescence.

Kinetic Grasp Can Absorb Abilities and Ultimates

Like D.Va's Defense Matrix, Sigma's Kinetic Grasp can absorb a variety of deadly abilities and ultimates when timed correctly. A list of significant ultimates and abilities that Kinetic Grasp blocks can be seen below:

  • Ultimates: Graviton Surge, Blizzard, Pulse Bomb, Death Blossom, Barrage, Dragonstrike, Dead Eye
  • Regular Abilities: Biotic Grenade, Dynamite, Concussion Mine, Fire Strike, Biotic Orb, Sleep Dart

Stay Active While Using Gravitic Flux

Remember that you can move around in the air while using Sigma's Gravitic Flux. Use this mobility to avoid enemy attacks and fine-tune the origin of the ultimate's gravity field.

In addition, you can also attack foes with your Hyperspheres after sending them into the air with Gravitic Flux, allowing you squeeze more damage out of your ultimate.

Coordinate Frequently With Your Team

Make frequent use of voice communication or the game's Ping System to make the most out of Sigma's Accretion and ultimate Gravitic Flux. Point out vulnerable foes stunned by Accretion, and coordinate Ultimate combos with your team using the Countdown ping.

Sigma Story

Life as Dr. Siebren

Sigma Story 1 Overwatch 2
Dr. Siebren de Kuiper was a pioneer in the study of gravity and how to harness it. It was this study that led to the accident that gave him the power to manipulate gravity, which would fluctuate with his emotions.

Turning Into Sigma

Sigma Story 2 Overwatch 2
Deemed dangerous, he was kept away from the rest of the world, dubbed Project Sigma. It was Talon that released him and used him to further their agendas. But with his mind forever changed by the accident, there's no telling what could happen.
