Bungie has released the campaign matchmaking playlist for Halo: Reach and also plans to add new playlists and tweak other elements of the multiplayer experience tomorrow, 19th October.
"Today we released the Campaign Matchmaking playlist and soon we'll declassify all of the imagery on Bungie.net," community man Eric Osborne wrote in the developer's weekly update.
"If you haven't completed the campaign yet, we're no longer going to hold your hand and shield your eyes from the sights and sounds of our furiously kickass campaign. It's been long enough.
"Be warned: if you jump into Campaign Matchmaking, you're liable to play the last mission first. If that doesn't bother you at all, go nuts. If it does, it's time to get crackin' on your campaign progress."
New playlists going live tomorrow are Team Snipers and Living Dead, and there are also numerous changes to existing playlists and modes detailed in the update. Next week, meanwhile, will see major changes to the Score Attack playlist in Firefight, including a leaderboard reset.
What of the new Noble Map Pack, though? How will that be supported?
"Unlike the map packs of yore, we won't only be offering a playlist specifically tailored for players with access to DLC," Osborne wrote.
"The haves and the have-nots can swim in the same pool and our newly retooled matchmaking algorithms will systematically segment the player base properly so you won't have to worry about where you can get your next hit of new map smell. They'll be seamlessly incorporated into the already existing playlists as primary voting options.
"Of course, for those who demand a DLC-only experience, we'll blow the whistle and open up a VIP lap lane just for you. It'll be ready to go on day one. Details coming soon."
The Noble Map Pack consists of three new maps and is set to cost 800 Microsoft Points (£6.80 / €9.60) when it comes out on 30th November.
