I have these brutes and they can only use:
-Gravity Hammer
-Plasma rifle
-Brute shot
-Plasma pistol.
I wont to add them using cmt spikers, excavator and other weapons. Also they dont know how to shot out of ghosts, wraiths and spectures.
How do i add this stuff to them

If you are talking about sheer ability to use and drive objects, that is due to animations.
Either new animations for the bipeds need to be added, or animations for weapons and vehicles need to be substituted with ones the brutes can use.

Testing if this works. In the actor file they had to crouch to fire and stuff. They hop into the vehicles but dont shot at all. Unless using basic halo 1 weapons.

Oh yeah, that's due to the actor_variants.

In your .model_animations file, at the top, under Units, select stand. Then, scroll down to weapons, and a bit further down to weapon labels. When you see pr, click duplicate. Rename your duplicate to the weapon label of whatever weapon you want it to use. Repeat for the crouch and alert units, and any other stances in which you want the brute to use that weapon.

ahha. Fixed it. The brute actor has couch do shoot and stuff. So i uncheked them and now they shoot and use vehicle proply. Thanks for the help though
