343i said back in e3 or later that BTB will be added two weeks post launch, so that would mean it’ll be released on the 10th. I imagine they’ll talk about it in the upcoming Weekly Update later today. Unless they lied about that also and it becomes another Soon™ or Delayed™ situation.
Yep. It’s coming in December.
10th of December?
YAY!!!
Doubt it but it would be nice if they did…
That’s what they said, it wouldn’t be a month from launch, but everyone saying that it’s coming in December
you brought my hopes up just to bring it down 
just read the update and it should be here this month I’m super excited
Its next week isn’t it? The way the weekly update was worded, it sounds like next week at least. As excited as I am, a certain series is releasing a new game which might be a problem…
A core playlist like BTB honestly should have been in since launch though. Warzone doesn’t replace BTB.
That misleading title though.
It’s launching on the 16th and they did not say two weeks, they said a few weeks which is three to five so if they wanted they could wait until the first week of December to release it with forge but it’s coming out in ten days instead
Big team battle is november its the other parts which are coming in november read the article lol
November Update: A Sneak Peek
In just over a week, the next Halo 5 content drop will be here, and with it comes Big Team Battle in Arena matchmaking, brand-new REQs, and a whole ton of juicy vehicular combat. Today, we’re giving you a sneak peek at what’s in store, and over the course of the next week, we’ll be providing you with more details.To start, we know many of you are ready for some vehicle-based carnage in Arena, and dying to jump into some classic 8v8 matches. You’re in luck.
Before the Halo 5: Guardians Multiplayer Beta, Josh Holmes approached me and asked “can we get a “Pro Team” equivalent of the best community Forgers to help us build Forge?” to which I responded “Yes. Yes we can.”
Fast forward a few months, and we’ve brought some of the community’s top Forgers in the studio: Warholic, The Fated Fire, The Psycho Duck, Nokyard, and Ducain23. As you saw in the Forge reveal, these gentlemen provided feedback on Forge tools and features that ultimately resulted in a wide variety of improvements across the feature set. During their time here, they also started working on large-scale Big Team Battle maps that were inspired by classic battlegrounds including: Sidewinder / Avalanche, Standoff, Burial Mounds, Longbow, and Headlong.
As you saw in the latest episode of The Sprint, each map maker selected a classic map on which to base their Big Team Battle map design. These guys built day and night, continually preparing and perfecting their maps for the next playtest with the multiplayer and level design teams. At the end of the week, we had solid canvases that offered a wide variety of BTB combat, and this meant that it was time for the maps to be handed off to the 343 team for continued iteration and development. The Forgers continued to provide feedback and direction for the map, and the team here at the studio continued to iterate on flow, polish, spawn and objective placement, look and feel, and more. For the past few months, these maps have been playtested and polished in preparation for the release of Big Team Battle, and in just over a week, the first four maps will be available in Arena matchmaking. Here’s a quick look at what’s to come:
I really wish they would bring back the mammoth for one map though, that thing really brought in a new dynamic to its map.
I certainly can’t wait 
Wow the BTB maps look terrible. I guess we will only have 8 original good looking maps for Slayer. It looks like a mess of objects in a forge map like Orion and Pegasus, which it is.
It is actually released on November 16th…the maps are:
- Basin (Valhalla Remix) - Guillotine (Headlong) - Deadlock (Standoff) - Recurve (Longbow)
The 10th!!! BUT OF WHAT MONTH?!
So is it December 10th or November 16th?
