HaloMods "Classic" Read-only Archive

I See a-lot of people having a hard time with Adding AI To this stage, you know in the beginning of the stage, on Easy u get 3 ODST's and in Hard you get 2, Well i changed it to about 5-6, but it don't work, i still only get the 2? How can i fix this and Add as many as i want like i did to every other stage before it..

I ones changed the grunts to masterchiefs.
And it worked.
I had like twenty masterchiefs at my side.
