343 Industries has released the Halo MCC Season 7 update today on both PC and Xbox and shows as version 1.2398.0.0! This Halo The Master Chief Collection patch clocks in a 12GB on PC, and a hefty 32GB on Xbox One!

Halo MCC Season 7 Update (1.2398.0.0) Patch Notes:

Update: Here’s the complete patch notes via 343!

New in this update

New Season 7 customization content

New cosmetic content for Halo: Combat Evolved, Halo 3, and Halo 4 is here as part of Season 7. For the first time, this includes new armor for Elites. The full breakdown:

• New Halo: Combat Evolved vehicle skins
• New Halo 3 Elite armors
• New Halo 3 Energy Sword colors
• New Halo 3 Techsuits
• Halo 4 weapon skins
• Halo 4 armors (the “Champions Bundle”)
• New static and animated nameplates

Custom Game Browser live for Halo: Reach

The long-awaited Custom Game Browser is live for Halo: Reach. Players can use the Browse menu to find other people’s custom games or the Create menu to customize and host their own custom game session.

Thank you to the players who helped us test the Custom Game Browser during the scale test. Since then, we improved the experience in many ways:

• Full game sessions now appear at the bottom of the list.
• The Session Name field now has a longer character limit.
• The game now informs the party leader if they try to join a game session, but a member of the party does not have necessary content installed.
• When “Repeat Game” is enabled, the pause menu now says “Next Game” instead of “End Game”
• Fixed several issues with sorting the list of sessions.
• Made several improvements to how voice and text chat work with parties during gameplay.
• Fixed exploits that allowed known cheaters into sessions.

New Halo 3 map: Edge

Originally made for Halo Online, the second new map for Halo 3, “Edge,” has been added and can appear in Social Matchmaking. Edge is a symmetrical map that supports all major game variants in Halo 3 with 4 to 12 players.

Fight with sentinel beams and silenced SMGs across an open cliff-side vista and secluded ancient database in this new map on the remote frontier world of Partition.

Waterfall and Edge maps added to Social Matchmaking

Players may now play on both new Halo 3 maps, “Waterfall” and “Edge,” when queued up in Social Matchmaking. Thank you for the player feedback that helped us make fixes and improve visual polish on both maps before moving them into matchmaking.

Firefight matchmaking is now in Social Matchmaking

To help give the Firefight community a boost, Firefight matchmaking is now part of the Social Matchmaking flow (you can read the blog post here). We expect this to help in several ways:

• The Firefight game mode will have increased visibility by appearing alongside other social game modes.
• The Halo 3: ODST and Halo: Reach Firefight communities will be closer together, improving queue times for everyone. Players can still choose to queue up for only one of the games if they prefer.
• Players can be more specific with the game types they search for.
• This creates the possibility of rotating Firefight options and categories.

Better visual authenticity for Halo: Combat Evolved 

Many graphical updates, from fog and shader effects to original character models and active camo quality, bring Halo: Combat Evolved even closer to the classic experience. Some updates include:

• Active Camo is closer to the original Xbox appearance, with a darker shade that is less reflective.
• Textures on all maps now display bump maps, which is most noticeable on metal and Forerunner surfaces
• The fog effects across multiple maps now render properly, such as above the canyon in Assault on the Control Room, Two Betrayals, 343 Guilty Spark, and Keyes.
• Covenant shields now react to being shot with plasma weapons by changing color.
• The visual effects of Jackal shields, teleporters, Spirit Dropships, and Cortana’s color pulsing while in the Ring’s control room now match the original Xbox version.
• Flashlight shine distance is further and better represents the distance on original Xbox version.
• Translucent textures such as the windows on Pillar of Autumn are no longer too opaque and now have the correct reflections.
• Captain Keyes’ original model from the Xbox version has returned.
• Layers of detail and reflection are now applied in the correct order on Master Chief’s armor, Forerunner doors, Pelican Dropships, and more.
• The screen flash that displays when picking up camo or taking a teleporter is now closer to the original Xbox version.
• Combat Flood forms and health packs now glow the way they did in original Xbox version.

Halo: Combat Evolved Hardcore playlist changes

We updated the Hardcore settings for Halo: Combat Evolved based on competitive player feedback to improve this playlist and align it with the modded competitive gameplay experience popularized by the competitive community on Xbox. This includes the following changes:

• Weapon ready effects only play for local players.
• Dropped weapons have disabled collision and material sounds.
• Disabled footstep sounds.
• Killfeed messages only display if they are related to a local player or their teammates.

Updates to the Extras menu

The Extras menu has been updated to play the terminals and cinematics from Halo: Combat Evolved, Halo 2, Halo 4, and Halo 2: Anniversary directly within the game instead of linking externally.

The other Extras menu options link externally:

• Credits
• Halo Support site
• Halo Nightfall (only visible on the Xbox version of MCC)
• Halo 5 (only visible on the Xbox version of MCC)

Halo: Combat Evolved mod tools and client support

For the first release of MCC’s Halo: Combat Evolved modding tools, we are including four different programs. Modders may be familiar with a few, but this release includes the most powerful tools available for Halo: Combat Evolved (for advanced users only!)

On top of that, we are releasing zip files of Halo: Combat Evolved’s level scripts and all the tag files that went into building the campaign and multiplayer levels.

These tools and files are being provided as-is, but we plan to make updates over time to address issues we see discussed in the mod community.

The full blog post on Steam goes into more detail about these tools.

You can download these tools through Steam.
