Tips for playing Sigma
Sigma is widely considered to be one of the harder characters to learn in the game. The key to using him effectively is mastering his main attack and chaining his various abilities.
The Hyperspheres take a lot of getting used to, as charging in and firing them recklessly can often lead to your shots bouncing away and doing nothing.
Maintaining the correct distance to ensure your shots explode close to enemies is key. The Hyperspheres also excel in small spaces, so remember to use their ability to ricochet off of surfaces to your advantage.
Sigma can quickly transfer from firing his regular attack to his Accretion ability, doing huge damage and stunning opponents. Using his ultimate gives Sigma a clear shot at enemies while they are in the air, and again as they are stunned for a short duration after they hit the ground.
The combination of activating Gravitic Flux, hitting two Hypersphere's in the air, slamming the opponent down, and then hitting two more shots on the ground is enough damage to kill almost any DPS character and do huge damage to anyone else.
Sigma is an aggressive tank, great for leading an attacking team. Be sure to make regular use of his defensive abilities to keep yourself alive, and keep your damage up to keep the enemy's focus on you. His Experimental Shield can be used and reused relatively quickly, so be sure to move it to more advantageous positions whenever possible.
Regardless, your main job as Sigma is to bully the other team into focusing on you. Keep up the pressure and they will be forced to buckle.
