Asphalt Legends Unite

The description here is a little misleading because the game refers to these as Nitro Shockwaves. To do one, you have to let your nitro meter (the yellow meter across the top of the screen) fill up all the way. Then, you can double tap the nitro button to use a Shockwave. You'll turn purple and burst forward at a very high speed.

You'll be doing this hundreds of times throughout your time with this game, so this achievement will unlock very early.
