📋 About This Mod
Replaces all the SEAF trooper NPCs with the UNSC Marines from Halo Reach
Seen a lot of people looking for this, and wanted it myself to complete my ODST modpack, so I made it lol.
INSTALL THIS MOD MANUALLY
- For whatever reason isn't being recognized when using Arsenal, so for the time being please just install manually.
ALL ARE UPDATED AGAIN as of 5/2/2026
- Please leave a comment or bug report if anything isnt working
- also int the future feel free to use the repatch tool if another game update breaks everything
REPATCH TOOL
- On the Helldivers 2 Modding Discord they have released a tool to repatch mod files!
- This should work with any mods
- I am aiming to repatch all of my existing mods using this tool eventually
- in the meantime, feel free to use it to repatch the older version of these mods for LOCAL use.
- Please do not reupload the patches of these mods without my permission.
- Link to the github release https://github.com/RaidingForPants/hd2-repatcher/releases
!! UPDATE !!
- you asked for it, so here it is . . .
- Added Marines with a balaclava (face mask)!
- As of now I would recommend using this version, as they don't suffer from the weird visual glitch on the head as the others do
- These also don't include backpacks that interfere with the EATs and other Backpacks the SEAF troopers have. (if you want a versions with the backpack for whatever reason drop a comment ig and I'll see what I can do)
- This was the most requested version, I'll probably make version with ODST next, but with a much lower priority, so it might take be a while.
I have also seen a lot of people asking for Halo 3 Marines, and good news, XEN0KID made an amazing mod for that!
Please go check out Halo 3 Marines - SEAF Soldiers if your interested in that, its some great work so be sure to give it a look!

✨ Key Features
📊 Pros & Cons
✅ Pros
- Simple cosmetic swap that adds Halo flavor to Helldivers 2
- Decent download count (7,207) shows community interest
- Lightweight mod with no reported performance impact
⚠️ Cons
- Only affects SEAF NPCs, not player models or other units
- May conflict with other mods that alter SEAF appearances
This is for Halo fans who want to see UNSC Marines in Helldivers 2, adding a nostalgic crossover. It's also for players who enjoy cosmetic tweaks to NPCs without changing gameplay. If you're not into Halo or don't care about SEAF visuals, this mod won't add much.
💡 Beginner Tips
- Make sure to place the mod files in the correct directory (usually the game's mod folder) to avoid issues.
- If you're using other mods that change SEAF NPCs, load this one last to ensure it takes priority.
