Experimental Barrier will best be used with another barrier Tank like Reinhardt or Orisa because it is powerful and moves quickly.
Working with a friendly Reinhardt or Orisa can assist in absorbing a large amount of damage with your multiple barriers.Using your barrier, you can advance through choke-points quickly and relocate your barrier after passing through it.This can potentially deny a game-changing enemy play, and it can help contest the objective by delaying/neutralizing an enemy's ability to use their Ultimate. Using the speed of the barrier, you can block the usage of Ultimates from Soldier 76, Pharah, Reaper, Reinhardt, Cassidy, Ashe (B.O.B.), Bastion, Roadhog, and sometimes D.Va (although she might destroy the barrier).Experimental Barrier is able to be used in a multitude of situations to save yourself and your team, and will rely heavily on your ability to respond quickly to the situation at hand.Experimental Barrier: A sizable barrier which can be deployed and retracted at will, and can be deployed at any area within Sigma's line of sight.Though their range is limited, their moderate damage can be used to whittle away at enemy barriers without exposing yourself.The minor gravitational effect can be utilized to slow down quick heroes such as Lucio, Soldier: 76, and Genji.The short range of the projectiles limits their ability to fight in open areas try to stay within an area that enemies congregate in, such as near enemy cover or in small quarters.These are best utilized in close spaces, where the Hyperspheres can bounce around obstacles and deal damage to multiple enemy players or players hiding behind corners. The projectiles' damage is moderate and consistent, though incapable of headshots.Their detonations have a minor gravity effect similar to Orisa's Halt!, though much weaker. Utilizes a two-round burst projectile fire which detonate shortly after firing, capable of damaging multiple enemies at one time and bouncing around corners to deal with heroes out of your direct view. Being able to distinguish when it's a good time to push forward and when it's better to stay behind your team will be instrumental to the survival of both yourself and your team. With that being said, Accretion and his Hyperspheres can quickly take out a singular escaping enemy, such as Lúcio or Tracer in these cases, finishing them off before they can flee is the correct play. Overextending with Sigma will in most cases result in dying a swift death likewise, if you believe your teammates are nearby but they've already fled from a fight, you're just as likely to be eliminated. While Sigma has the capability to deal a lot of damage, his lack of mobility will make any situation where you're stranded alone and surrounded by enemies a disaster. Sigma's abilities can give off the perception that he is stronger than he is, which can make it tempting for players to play overly aggressive with him. Quick thinking and superb situational awareness is needed when using Kinetic Grasp to protect himself and his team. While he is capable of high damage output, he is most useful when fighting at a distance with Accretion and Hyperspheres while making openings and defending his team with his versatile Experimental Barrier. However, his lengthy cooldowns requires one to think ahead rather than freely using his abilities. Sigma is a Tank Hero boasting both consistent offensive and defensive abilities. Gravitic Flux’s Area of Effect is slightly larger than the marker indicates, so enemies within 0.5-1 meter of the edge of the indicator will also get lifted and receive all damage.Sigma can fire his Hyperspheres during the lifting period.The lift can be damage boosted but not the slam.Those affected by the slam experience high gravity and are massively slowed for 0.6 seconds.
The slam deals 50% of the maximum HP, which is increased by temporary HP gained from abilities such as Rally.If enemies escape the suspension, such as with Fortify or Cryo-Freeze, they fall down and no damage is inflicted.No fall damage would be inflicted to lifted targets. The ultimate can be interrupted up until the slam.Disables all movement abilities of enemies suspended in the air, except Moira's Fade and Reaper's Wraith Form.Does not affect deployed objects such as turrets (but it does move Bastion in Sentry mode).If no area is selected or if there is no enemies inside, the ultimate ends immediately.
Enemies entering target range after the lifting will not be affected.
