Loader: Earthshatter

 is a challenge in Risk of Rain 2. It is completed as Loader by landing a Charged Gauntlet hit at 300mph or higher.

Tips

 * An easy way to do this, is by punching downward, while in the air.
 * Another way to do this in an environment that has launch pads. Make sure a monster is on the other side of a launch pad's trajectory and fully charge the gauntlet before taking the launch pad.
