The Halo veteran player actually manages to make it through the entire Halo 2 campaign on Legendary difficulty without dying a single time.
In total, the streamer manages to beat Halo 2 on LASO (Legendary All Skulls On) difficulty in right around six and a half hours.At the time, the streamer acknowledged that Jervalin had come close to completing the feat beforehand, only coming short of a full LASO run because he kept the 'Envy' Skull on, letting him turn invisible at will.
Now Jervalin has taken the crown and finally accomplished the entire challenge!
