Halo: Campaign Evolved, released this week, has already attracted a wave of fan-made mods, ranging from useful quality-of-life tweaks to outright joke additions. Modders are using the foundations of the game's Unreal Engine remake to overhaul both its visuals and gameplay, adding to the buzz around the title's launch, which also includes a secret ending widely seen as teasing a Halo 2 remake.

Notable mods let players replace Master Chief with Carl Johnson from Grand Theft Auto: San Andreas, or with Iron Man, alongside options to play as Brutes or custom Spartans. Other additions include a third-person camera view, graphical overhauls ranging from more realistic visuals to retro PS1-style graphics, a dynamic day/night cycle, new and reworked weapons, a Halo: Reach-style jetpack, and split-screen support for PC, which is otherwise only available on consoles. Fans looking to try them can find the mods on NexusMods.
