Ironically same to spanish translation, except zolya has no gender issues.

Vaulters is translated to "saltadores", if you put this back in google translate you can see it literallymeans "jumpers"

Strangely enough each one of those definitions fits the faction in its own right. Maybe from a different angle

Sorry. No.

Vaulters come from VAULT, refering to its lore of having to refuge underground into a big VAULT.

The teleport ability is cool in bith ES and EL, but has nothing to do with its lore. It will be like translating Cravers into "comeplanetas" (planet eaters). Descriptive, but not lore consistent.

Also "saltadores" is not cool as Vaulters.

For now I returned to english. Well really only played spanish to check the translation. I'm from a time were all games were in english, so is strange fir me to play other languges.
