Halo: The Master Chief Collection

Halo: The Master Chief Collection presented a deceptively complex UX challenge. Four technically incompatible game engines, each with their own save systems, stat tracking, and multiplayer infrastructure, had to feel like a single, unified experience to the player.

In a standard video game collection, each title exists in its own isolated silo. Switching games means killing the active software, clearing system memory, and booting an entirely new application. United Front Games' mission was to destroy that model entirely, to build a single, permanent wrapper interface that could dynamically launch, manage, and swap these massive legacy engines behind the scenes, without the player ever feeling the seams.

The design goal was simple to state and hard to execute: the player should never feel the architecture.

As part of the UX team at United Front Games, my responsibilities spanned the full design lifecycle of the menu system:

• Wireframes, lo-fi structure and flow mapping through to high-polish documentation covering all user flows across the entire game menu system
• Art direction and UI design, applying visual design to interface elements in line with the Halo brand and direction provided by 343 Industries and Microsoft
• Motion prototypes, creating motion graphic proof-of-concept videos compiled from team design work, used for stakeholder review and sign-off with 343i and Microsoft
• Legacy UI enhancements, refinements and improvements to existing UI patterns across the collection's individual titles

UFG engineered the interface to act as a universal master controller. When a player selected a level, the menu fed data directly to the hardware to spin up the specific legacy engine required on the fly, making the transition feel as fluid as switching chapters on a Blu-ray disc, not launching a separate application.

Every Halo game also tracked progress, stats, achievements, and gameplay modifiers in entirely different ways. Halo 1 had no standard level-select save state for individual Skulls. Halo 2 tracked playlists differently than Halo 3. UFG created a centralised database layer, the Master Menu intercepted all of these disparate data streams and translated them into a single, standardised dashboard.

This is what made Cross-Game Playlists possible. The menu tracked overall progress while passing the torch from engine to engine as players advanced, all within one unbroken session.

In the original games, your party lobby was tied strictly to a specific game's engine. UFG's menu system had to keep a group of friends connected in a single voice and text party while the underlying game engines beneath them changed constantly based on what map the lobby voted for next.

The following documents represent the foundational structure work done before visual polish or art direction was applied. These were the bones, laying out tile systems, card patterns, grid logic, and navigation hierarchies while staying true to Halo's imagery and iconography provided by 343 Industries and Microsoft.

Once the art direction was more finalised, the Groundhog style guide documented the full component spec, including animation and shimmer states, typography, and the global look and feel of UI components across the collection.
