Symmetra

When you shoot the barrier, the Photon Projector instantly reaches maximum power, allowing you to melt the large targets that come flying at you.

You can shoot the Barrier Array to maximize the Photon Projector

You can use the Experimental Barrier to amplify the beam and burn the main unit.

Maximize your beam with the Barrier Field, and use the Sentry Turret to chip away at the enemy's health as they advance.

You can level up your beam attack against the Void Barrier

The beam from the photon projector cannot be blocked by the defense matrix.

Photon Projector's beam can't be reflected by Deflect, and Sentry Turret punishes any approach too.

Can launch one-sided attacks from the sky, beyond the range of the beam

You can destroy teleporters and sentry turrets with the Jagged Wall, and you can take out the main unit with the Violent Leap.

Use dynamite to take out a bunch of sentry turrets at once, and chip away at the main body from outside the beam's range.

Can attack unilaterally from the air, out of the beam's range

I keep taking damage from far beyond the beam's range

You can target enemies one-sidedly from outside the beam's range

You can take out a sentry turret with a ricocheting grenade without getting in its line of fire.

You can hack to disable sentry turrets and teleporters

You can target enemies one-sidedly from far beyond the beam's range

You can trap Symmetra—who needs to get within beam range—within the Chain Hook's range.
