A recently released mod enables split-screen cooperative play for Halo: Campaign Evolved on PC, a feature that was omitted from the game's official PC version despite its availability on current-generation consoles. The mod, found on Nexus Mods, brings local split-screen functionality to PC players, mirroring the experience offered on PlayStation 5 and Xbox Series X/S.
The mod's creator discovered that the necessary code and UI elements for split-screen are present within the PC build of Halo: Campaign Evolved and were merely deactivated. The modification reportedly activates a second local player at runtime via UE4SS without altering the game's executable file. It achieves this by clearing the two specific elements that prevent the feature from functioning.
Despite its functionality, the mod comes with certain limitations. Activation requires a hotkey, which may not be ideal for all PC gaming setups. Furthermore, the mod currently supports only two-player split-screen, a reduction from the four-player capability found on consoles. It has also been tested exclusively with the Steam version of Campaign Evolved, and compatibility with the Microsoft Store (Game Pass) version is unconfirmed. Some reports suggest that both players must use controllers for the mod to function correctly. Additionally, a visual quirk causes subtitles to display across both screens simultaneously rather than on a per-player basis.
The mod's development was partially assisted by Anthropic's Claude Code AI, which may influence its potential for future improvements or changes. The creator's familiarity with coding could impact the mod's evolution over time. This situation arises as recent technical analyses have indicated that Halo: Campaign Evolved performs better on the PlayStation 5 compared to the Xbox Series X.
