Death Knight Joins Quake Champions

Quake Champions Website has patch notes from the August patch which is now live in id Software's multiplayer shooter (thanks PCGamesN). The has changes, fixes, and adds new items, including a heavy machinegun which will only be unlockable during QuakeCon. It also adds the Death Knight from the original QUAKE as a playable character. Here's word:
A new Champion rises from the fire to slake his unending desire for carnage! Available to play today, Death Knight will be a familiar face to Quake fans, as this armor-clad enemy sought to stop Ranger from defeating Shub-Ngurath with his fireball-spewing sword. The massive energies released by the Outer God’s defeat launched them both into the Dreamlands, and now Death Knight stalks him—and anyone else who crosses his path!
