The Vault is a simple technique used to maneuver over small environmental obstacles. The user leaps over the obstacle with one hand planted and lands on top in a position similar to a Duck, remaining idle for a short amount of time before returning to a stance.
In the the Wii U version and PC version of Sonic Lost World, the Vault is used by Sonic and Super Sonic. In the former, it is also used by the Virtual Hedgehogs. In gameplay, the Vault is used to get over low walls without losing momentum from jumping or ramming into walls. To perform the Vault in gameplay, the player can hold to Dash toward a low wall. If the player needs to Vault faster, they can perform a Vault Dash.
