Halo Master Chief Collection Season 6 Patch Notes

Here are the notes in full, courtesy of Halo Waypoint:

Season 6: Raven

Season 6 “Raven” has begun, bringing 100 new tiers of customizations to unlock. That includes:

  • New armors based on Fireteam Raven and Halo Online for Halo 3
  • New back accessory customizations for Halo 3
  • New animated visors for Halo 3
  • New animated nameplates
  • New techsuit colors

Season 6 also brings a new batch of challenges to complete for season points. For more info, check the Season 6 launch blog on Halo Waypoint.

The Exchange

Players can now use the Exchange to spend season points on unique customizations from past Seasons or limited-time challenges. Visit the Exchange from the main menu to see what’s currently available.

New Halo 3 Map: “Waterfall”

Originally made for Halo Online, the map Waterfall is now available in Halo 3 Custom Games. Waterfall is a symmetrical map that supports all major game variants in Halo 3.

Waterfall received significant updates after flight testing, but we would like to gather more data from players around performance or bugs so we can make sure Waterfall is ready to enter the regular rotation in matchmaking.

New game variant: “Escalation Slayer”

In Escalation Slayer, players progress through a series of weapons by earning kills with each one. When a player gets a kill with the final weapon, they win the round. You can also downgrade opponents to the previous weapon tier by assassinating them or sticking them with a Plasma Grenade.

Escalation Slayer will be available in Halo: Reach, Halo 4, and Halo 2: Anniversary. Players can configure game settings to customize the experience and create unique variants.

Team Changing in Custom Games

In Custom Games across all multiplayer titles, all players can now change teams during a match. Choose Leader Only, Pre-Game Only, or Always options while setting up the Custom Game lobby. (Always is the default setting).

Mouse & Keyboard support for Xbox

Console players can now play using a mouse and keyboard with this feature supported for Xbox.

Secondary bindings for Mouse & Keyboard

Any action can now be bound to multiple inputs while using mouse and keyboard.

Field-of-View (FOV) and Crosshair Position options for Xbox

  • Game audio output device
  • Voice chat input device
  • Voice chat output device
  • Voice chat threshold

These settings will override the Windows default settings.
