Please Lamaboy, stop saying you started the AI mod craze. The reason they started to appear more frequently is a mix of several good tutorials for how to do them, and just general realization that you can make an (simple) AI mod easily... Your mod probably had nothing more than a minor impact on this "craze", but no more than a minor one.
Back on topic, you should put a little more work into it. This probably didnt take that long for you to make, so I say double or tripple the time you've used so far, maybe add some custom content, and Im sure it will be a good mod.

Not saying it's bad now, Im saying it can get lots better.
Oh, and I'll go with the rest of the crowd and say colour the spartans. If you dont know how to do this, Open up Guerilla, and open the Cyborg Actor Variant tag. Scroll to the bottom of the tag and look for "change colour". You will see two boxes, probably white. Klick them and pick a colour from the pallette. The top colour will be the main colour, and the bottom box sort of tints the armour. (For Elites, The top box controls half of the armour parts, the bottom one the other parts and tinting. You can get venom green Elites this way.

) Go to file - Save as... and save it as whatever you like. Add your new actor variant tag to your map as usual. Voila.
(Also works for Grunts and Elites.. Might do for others as well.)
