Welcome to our comprehensive guide on Sigma, the 31st hero to join the action-packed world of Overwatch. As a tank hero with unparalleled control over gravity, Sigma has quickly become a favorite amongst players since his release on 13 August 2019. In this guide, we will delve into Sigma’s mesmerizing lore, uncover his powerful abilities, and provide invaluable tips to help you maximize your gameplay potential.

Understanding Sigma’s Abilities

Sigma, the 31st hero in Overwatch, brings a unique set of abilities that make him a force to be reckoned with on the battlefield. Mastering these abilities is key to maximizing Sigma’s gameplay potential. Let’s take a closer look at each of Sigma’s abilities:


Sigma’s primary weapon, the Hyperspheres, consists of gravitic balls that bounce off walls and implode upon impact, dealing damage to enemies within a radius. These versatile projectiles can be used to control areas and inflict significant damage on multiple targets.

Experimental Barrier

One of Sigma’s defensive abilities is the Experimental Barrier. This floating shield can be deployed and recalled at will, providing cover for both Sigma and his teammates. The barrier is particularly useful for creating space and advancing your team’s position while maintaining protection.

Kinetic Grasp

With the Kinetic Grasp ability, Sigma can absorb incoming projectiles and convert them into shields. This defensive maneuver not only helps to mitigate damage but also provides Sigma with additional protection against enemy assaults. Be strategic in using Kinetic Grasp to absorb high-damage projectiles or crowd-control abilities.


Sigma’s Accretion ability allows him to unleash a powerful rock-like projectile that can stun and damage enemies. This versatile tool can disrupt enemy movements, interrupt abilities, and secure key eliminations. Make sure to time your Accretion throws well to maximize its impact.

Gravitic Flux

Sigma’s ultimate ability is the Gravitic Flux. With this ability, Sigma can lift enemies into the air and slam them back down, dealing massive damage. Gravitic Flux is particularly effective at initiating team fights or countering enemy ultimates by disrupting their positioning and forcing them to scatter.

Understanding and mastering Sigma’s abilities is key to becoming a formidable force on the Overwatch battlefield. Experiment with different strategies and combinations to maximize your impact and contribute to your team’s success.

Mastering Sigma’s Strategies

To excel with Sigma in Overwatch, it is crucial to understand and utilize his unique strategies. Sigma’s versatile kit allows him to control areas, provide cover for his team, absorb damage, disrupt enemy movements, and unleash devastating attacks. By mastering these strategies, you can maximize your impact on the battlefield and lead your team to victory.

Controlling Areas with Hyperspheres

Sigma’s primary weapon, the Hyperspheres, can be a potent tool for controlling areas and dealing damage. These gravitic balls bounce off walls and implode, damaging enemies within their radius. To effectively utilize the Hyperspheres, aim for areas where enemies are grouped together or are likely to pass through. Coordinate with your teammates to capitalize on the damage dealt by the explosions. Additionally, use the bouncing nature of the Hyperspheres to your advantage by aiming them strategically around corners and obstacles to catch enemies off guard.

Creating Space with Experimental Barrier

The Experimental Barrier is a floating shield that Sigma can deploy and recall at will. It provides cover for both yourself and your teammates, allowing your team to advance while remaining protected. When deploying the Experimental Barrier, consider the positioning of your team and the objectives at hand. Use it to block incoming enemy fire, protect vulnerable teammates, or create a safe zone for your team to regroup or secure objectives. Remember to recall the barrier when it’s no longer needed to preserve its durability for future use.

Withstanding Enemy Assaults with Kinetic Grasp

Sigma’s Kinetic Grasp ability is a lifesaver when it comes to absorbing incoming damage and providing shields. Activate Kinetic Grasp when you anticipate a burst of enemy fire or when facing heroes with high-damage projectiles. This ability not only protects you but also generates shields that can help withstand enemy assaults. Utilize Kinetic Grasp to soak up damage, protect yourself, and maintain your presence on the battlefield.

Disrupting Movements and Securing Eliminations with Accretion

Accretion is Sigma’s ability to hurl a powerful rock-like projectile at enemies, stunning and damaging them. This ability can be used to disrupt enemy movements, interrupt ultimates, or secure key eliminations. Aim for vulnerable targets or use Accretion to stop enemies from advancing or escaping. A well-timed Accretion can turn the tide of a battle and allow your team to gain the upper hand. Practice your aim and use this ability strategically to maximize its impact.

Capitalizing on Opportunities with Gravitic Flux

Sigma’s ultimate ability, Gravitic Flux, can be a game-changer in team fights. It allows Sigma to lift enemies into the air and slam them back down, dealing massive damage. To make the most of Gravitic Flux, look for opportune moments to use it. Use it to initiate team fights, catch key targets off guard, or counter enemy ultimates. Coordinate with your team to follow up on the damage dealt by Gravitic Flux, ensuring maximum impact and securing crucial kills.

Mastering Sigma’s strategies requires practice, coordination, and a deep understanding of his unique abilities. By effectively controlling areas, providing cover, absorbing damage, disrupting movements, and capitalizing on opportunities, you can become a formidable force on the battlefield as Sigma. Remember, adaptability and communication are key to unleashing the full potential of this powerful hero.

Unveiling Sigma’s Lore and Skins
