Free-to-play Nosgoth has introduced the new Vanguard class to the human faction, and they can take a lot more punishment than their comrades-in-arms, but have reduced range damage as a result.
This new class can be unlocked with an artefact, or by ”purchasing it directly” from the in-game store with Runestones. The Vanguard can be customised with new skins for the character as well as weapons.
A full breakdown of the new human Vanguard class is available on the official Nosgoth website. Currently the free-to-play title from Psyonix is in Open Beta and available through Steam.
