- For the information about attacks which is able to pierce through Symmetra's barrier, see Barrier.
Symmetra created an oval shield, which is 3.5 meter tall and 5 meter wide, in front of her. The shield will travel infinitely forward with the speed of approximately 5.5 meter per second (same as Symmetra's walking speed) until the center core comes in to contact with a piece of environment.
The barrier has a 1000 health limit and will block all incoming damage from enemies for as long as it is in front of them. It will pass through enemies without any effect.
