What is the name of the in-engine visual piece that first teased Campaign Evolved?

The in-engine visual piece that first teased Campaign Evolved was called Project Foundry.

Halo Studios presented Foundry in October 2024 while revealing its move toward Unreal Engine 5. It was not the game’s title or a conventional playable demo; it was an exploratory project used to investigate how Halo’s visual identity, environments, materials, lighting, and atmosphere could work in the new engine.

The presentation showed familiar Halo-inspired landscapes and design language, which led viewers to connect it with a possible Combat Evolved remake. That connection proved significant when Halo: Campaign Evolved was officially announced the following year as a ground-up remake of the original campaign.

Foundry is therefore best understood as a research and visual-development effort that helped establish the remake’s direction. Alpha Halo is the setting associated with the original adventure, while Operation METEORITE is a separate Campaign Evolved mission title; neither names the early visual exploration project.
