Sure, it's not really TOO hard. Use HHT and go under the ACTV tag. I'll be suing the Marine_armored_assaultrifle_major. Where it says ACTR, you wantto select your highest ranking elite, such as the commander, or major. LEAVE THE ACTV TAG ALONE. Where it says biped, make it Cyborg. And you can give him a new weapon, oe leave it be. Here's the tricky part, you need to make a second cyborg biped for the covenant team. Using HHT4, save the meta (NOT RECURSIVE) and inject it over something large enough. I used the Hunter biped in mine. call it cyborg 2 or whatever. on the covenant side, change the biped to cyborg 2/ Then open you map in HMT. Go to your new biped and change it from Player to Covenant. If you have the actv plugin, tou can alter their accuracy, health, shields, and various other things such as asctive camo. I added some pics of what you should come out with, and what your HMT ACTV tag should look like.
