  • Weapon Name: Hyperspheres
  • Damage: 110 (55 per ball

Sigma carries a high-tech firearm as his primary, which is an advanced projectile launcher that unleashes two-round burst projectiles that explodes after covering a certain range. The weapon causes explosive damage and has the ability to damage multiple enemies at once, with the direct as well as bouncing effect. The projectile detonations show a minor gravity effect, just like the Orisa‘s Halt.

As the projectiles deal explosive damage, the DPS of the weapon is compromised a bit, but the consistent rounds from the weapon can bring sturdy opponents down. The performance of Sigma’s weapon is maximized in close pavements, where the Hyperspheres can rebound with the objects and hit multiple enemies around the corners.

In open areas, Sigma lacks a bit in one on one fights, as the projectiles don’t have obstacles to bounce on. Although the damage of projectiles is mediocre, they can be utilized in attacking enemy AO without exposing yourself.

Type: Primary Attack

It is a basic primary attack in which two projectiles release from the weapon and burst upon hitting the enemy, dealing explosive damage. Using Hypersphere on a large number of the enemy is a great tactic as it will bring all of them down in a few hits. As the projectile have a considerably larger hitbox, it can be used to take down aerial targets as well.

The projectiles have a decent DPS of about 74. The main perk of this attack is that it can bounce off walls and obstacles to hit the target. One thing to keep in mind is that the projectiles have a range limit of 22 meters and will explode automatically after that, whether it has reached the target or not.

If the target is within the limit range, then the orb will explode on reaching the target. The projectiles also show a minimal downward path, enabling them to reach distant locations.

Tips & Tricks

  • While encountering enemies, try to take fight within closed spaces and indoor areas. It will help in enhancing Sigma’s abilities as he can utilize his bounce effect as well.
  • Always save up your Ultimate ability and use it in critical situations only, as it takes a long time to charge it back. You can also coordinate with your teammates to synchronize your special ability and form a strategic attacking play style.
  • Sigma floats in the air and does not produce any audible footsteps sound. This makes him quite a stealthy player, which you can use to flank your opponents and sneak in from behind.
  • Sigma is a ranged troop and is most efficient in taking out enemies at a distance. So, make sure to maintain some space while playing with Sigma so you can use his abilities more efficiently.
  • Sigma can be a great means to cover up your team’s vulnerabilities. You can put him on the front line-up and use his defensive abilities to distract the enemy troops and take them down at the right moment.
  • You can use the Experimental Barrier to detonate all the mines from Wrecking Ball’s ultimate ability without taking any damage.
  • The best strategy is to put Sigma in the front lineup to be aggressive on the enemies and, during his cooldown time, use his defensive abilities to support the allies.

Sigma is quite good against his rivals and Damage players, as he can create barriers and shields to counter their attacks. His blocking abilities distract the enemies as they start to focus on Sigma a bit too much, making them vulnerable to attack.

Wrapping Up

Sigma is a Tank character in Overwatch 2 who possess a mix of defensive and offensive abilities. Although his shields and barrier are a great asset, his cooldown duration for his special abilities is a bit longer than it should be. He is capable of decent damage output and performs best in closed spaces, where he can take the assistance of the walls and obstacles to bounce off his projectiles.

Sigma is a suitable character for medium-paced players who play neither too aggressive nor too passively. In order to unlock Sigma, you have to complete 40 matches, so make sure you grind for it and get the deserving reward.
