+# Halo: The Master Chief Collection
+
+Halo: The Master Chief Collection (MCC) contains multiple Halo games under one launcher, but in speedrunning terms it is **not treated as a single game**.
+
+Each Halo title inside MCC has its own categories, rules, and timing expectations. This page explains how Halo speedrunning is structured at a high level, and how the individual game pages fit into that.
+
+---
+
+## Where the rules and leaderboards live
+
+Halo speedrunning uses **[haloruns.com](haloruns.com)** for:
+- rules
+- category definitions
+- timing requirements
+- leaderboard submissions
+
+That site is where decisions are made and where official information lives.  
+If there is ever a difference between what’s written here and what’s on haloruns, the haloruns rules take priority.
+
+Main rules page:  
+[https://haloruns.com/rules](https://haloruns.com/rules)
+
+---
+
+## How MCC is treated in speedrunning
+
+Even though MCC is a single collection, runs are organised by **individual game**, not by the collection as a whole.
+
+The MCC titles commonly run are:
+- Halo: Combat Evolved
+- Halo 2
+- Halo 3
+- Halo 3: ODST
+- Halo: Reach
+- Halo 4
+
+Each of these games:
+- has its own categories
+- may use different timing methods
+- may have different version or setting expectations
+
+---
+
+## Timing methods
+
+There is no single timing method that applies to all MCC games.
+
+Depending on the game and category, runs may use:
+- In-game time
+- Theatre time
+- RTA - loads
+
+All of this is defined on haloruns and enforced per game.  
+The sub-pages here focus on summarising what you actually need to set up for that specific game before running.
+
+---
+
+## Versions and downpatching
+
+Version behaviour matters for some Halo runs.
+
+Some games and categories are fine on the latest MCC version. Others rely on older behaviour, which can mean:
+- specific game versions
+- avoiding certain updates
+- downpatching on PC
+
+This is not universal across MCC. Whether it matters depends on the game and category.  
+Individual game pages will call this out where relevant.
+
+There is also a tool to help you downpatch located here: [https://halo.downpatch.com](https://halo.downpatch.com)
