Before using [E] High Gear, pull out your gun so that when you stop running or slide, you don't increase length of the weapon pull out animation (even if you pull out your weapon right after stopping [E] High Gear)
[C] Fast Lane has a very long range, but can be blocked by terrain. To avoid this, make sure your crosshair is placed above any terrain in front of you. This will extend the wall beyond the obstacle.
While using [E] High Gear, Neon cannot use her weapon, but she can instantly cast any of her other abilities without canceling [E] High Gear.
When sliding out of [E] High Gear, your gun does not immediately have perfect accuracy. If you're using a Phantom or Vandal, get comfortable with when you can shoot with accuracy out of a slide.
