Season 6

Four months after the wedding crash that ended season five, the toys are still banned from Halo online. Master Chief passes the time by doodling on walls and burning holes in the carpet. The Arbiter, estranged from Claire, has sunk into alcoholism and self-loathing. Greg has vanished without a trace. Meanwhile, the OMN (Online Multiplayer Network) forms the TOSERS—Terms of Service Enforcement/Response Squad—to combat cheating and hacking. In retaliation, a ruthless hacker clan called Chaos Theosis emerges, unleashing FragBan, an illegal patch that lets players permanently ban and steal data from anyone they frag—unless the TOSERS are disbanded once and for all.

Master Chief follows through with his decision to apply to the TOSERS in-game police organization to have his online multiplayer access reinstated. Arbiter refuses to join him, unable to shake himself out of his depressive funk.

Master Chief and the Arbiter form an uneasy alliance with Cody and Cameron, fellow TOSERS applicants and once bodyguards of Trent Donnovich at his wedding, to fight off the hacker clan Chaos Theosis.

After Arbiter catches Master Chief making a mysterious phone call, the two set out to moderate Halo: Reach online play as newly recruited TOSERS.

The Arbiter and Master Chief begin their duty as level negative one TOSERS in-game moderators. Meanwhile, the Chaos Theosis clan continues its merciless rampage throughout online matchmaking.

Master Chief collapses from exhaustion after a full day of moderating duty. The Arbiter can't sleep and decides to resume play through the night -- and a newly promoted Claire is assigned as his supervisor.

Arbiter makes a last-ditch effort to retain the toys' positions on the TOSERS moderation force.

Master Chief and the Arbiter are in the belly of a private hacking server at severe risk of having their console irreversibly banned and must find a way out, but not without the hack files they came for.

Chaos Theosis attacks the TOSERS main operations server, killing every moderator in sight. Meanwhile, the toys are still stuck in a power outage.

Master Chief and the Arbiter, having pinned up mugshots of each member of the Chaos Theosis clan on the apartment's front door (their "hit list"), label each with their gamer tags and settle on tracking and taking out the youngest member of the clan first, Claire's killer -- Adam.

Kylie confronts Duncan regarding his avoidance of the tasks assigned to him by Clyde, and the toys bicker over who to make their next target.

Master Chief and the Arbiter target the remaining Chaos Theosis members on their hit list.

Master Chief and the Arbiter face off with Trent Donnovich, who has been revealed to be behind Chaos Theosis and their attack on the network.

It's Christmas, and Master Chief and Arbiter hang their stockings up for gifts from Santa.

Master Chief, having opened his gift from "Santa" early, a copy of Halo Anniversary, immediately proceeds to play it all the way to the new year.
