Human-Vault-Extension Tech.

By pushing yourself all the way into an object or against something that can not usually be vaulted due to lack of landing space, you can create a vault for another player the same way a Goyo canister or Ace charge would. This can be done by standing or crouching, proning has not been tested yet but it either is redundant because you can just run on the object anyways, or it simply doesn't add the vault prompt. However, some spots require you to be standing, and others crouch, no spot allows for both standing and crouch, just one or the other. If you can not find a natural vault onto it, it is very likely that placing a shield or Kiba Barrier will add the vault.
