Halo: Campaign Evolved Players Uncover Hidden PC Split-Screen Mode

A Nexus Mods user found hidden split-screen support in Halo: Campaign Evolved’s PC files, including configs, HUD, UI, audio, and VFX assets.

They released a UE4SS-based mod that enables the dormant feature at runtime instead of rewriting the game.

The mod currently targets the Steam version and may not work on the Xbox app release.

The discovery suggests the PC build still contains local co-op code that many players expected to see supported.
