Ultimate Engine Tweaks Mod
Ultimate Engine Tweaks mod delivers Unreal Engine.ini optimizations that eliminate most stutters, boost performance and stability, reduce input latency, and enhance visual clarity without any quality loss. It also includes tuned Film Grain, Motion Blur, Chromatic Aberration removal, and improved upscaling and anti-aliasing. Separate VRR and No-VRR variants are also available.
Hidden Skins Unlocker Mod
Hidden Skins Unlocker mod unlocks hidden weapon and armor skins that are normally unobtainable in the game. It includes skins like Assault Rifle Heroic Power, Fantastic Spartan, Ember, Shadowfrost, and many more. Note that this mod does not unlock DLC or pre-order content.
Skull Unlocker Mod
Skull Unlocker mod automatically unlocks all 44 campaign skulls plus LASO and Remix menus on game launch. Note that it requires UE4SS and a simple drop-in Lua script installation. If you want instant access to skull modifiers without completing challenges, then definitely download this mod.
Split-screen Co-op Mod
Halo: Campaign Evolved Split-screen Co-op mod adds local split-screen co-op to the PC version of the game, just like in console builds. It uses UE4SS to enable a second player at runtime and supports two players with teleporting. This mod requires Steam version, controllers, and UE4SS setup, but it’s a perfect solution for couch co-op on one PC.
100% Save File Mod
100% Save File mod provides a 100% complete save file with all missions, rally points, skulls, and terminals unlocked. It grants full content access without grinding. All you need to do is place the files in the SaveGames folder. In this way, you can jump straight into the endgame or test any features you like.
Mark IV in Main Campaign Mod
Mark IV in Main Campaign mod allows you to equip and use the classic Mark IV armor from the prequel campaign within the main story of Halo: Campaign Evolved. All you need to do is place the three files into the game’s Paks folder. If you miss the nostalgic Spartan visuals and armor aesthetics, then this would be the best solution.
Cortana Restored Mod
Cortana Restored mod restores nearly all original Halo: Combat Evolved Cortana voice lines in place of the re-recorded versions, while completely removing excessive hand-holding dialogue and cutscenes. Note that this mod works only in the English localization.
OG Magnum Firing Sound Mod
OG Magnum Firing Sound mod replaces the Magnum’s firing sound effect with the original iconic Halo: Combat Evolved version. It’s a straightforward audio mod that brings back classic weapon feedback with authentic Halo CE audio for your pleasure.
Enhanced Difficulty Modifier Editor Mod
Enhanced Difficulty Modifier Editor is a standalone tool that lets you edit difficulty modifier profiles outside the game. It unlocks advanced settings like invincibility, instant kill, active camo, speed, gravity, and more. It works across PC, Xbox, and PlayStation versions via a simple executable file with no in-game requirements beyond initial setup, which is great for custom challenge creation.
Instant 1st to 3rd Person Mod
This mod includes an instant 1st to 3rd person toggle, where no Skull is needed anymore, with instant switching between the views at any time with a default “B” key. It also includes shoulder swap with functional aiming and supports both Steam and Game Pass versions.
