Things You'll Need
Instructions
Back up all of your .map files before modding in case of corruption.
Launch Halo Hacker Tools version 5 from your PC. Open the desired map, such as Pillar of Autumn.
Scroll down to find the "Mode" group. Click on the grunt model. Choose "Extract" (recursive). Open the "Antr" group. Click on the grunt animation trigger. Choose "Extract" (not recursive). Click on the collision trigger and extract (recursive). Open the "Foot" group and extract the walk sound (recursive).
Open the map you in which you want to import the grunts, such as Rat Race.
Open the "Mode" group. Highlight the cyborg model. Inject the meta that you extracted earlier (recursive). Open the "Antr" group and import the animation trigger. All "snd!" references will change to "unknown" in the dependency swapper. Select all and swap them to "Nulled out." Inject the "Foot" group as before (recursive).
Navigate to and swap the cyborg_mp biped with the grunt model. Change the camera's standing height to "0,38" and the crouching height to "0,28."
Copy the modified file to your Xbox. Launch to play as a grunt.
