Hahaha, unfeasible in any capacity, especially considering the fact that even the original devs have abandoned the idea of infantry and threw it in half-baked at the last second as a silly useless mod and never came back to it. Besides, after the Clans game launches all the people and modders will most likely flock to it for quite a while. But yeah... people can still dream, I guess - no taking away that :]

Would be so much system resources tied up generating nothing tangible in a title that is already very demanding.

Not saying you cant want what you want but this is the reality.
People are there however if you look real close at the towers you demolish as they fly out the side with all the rubble.

Use this and pretend. Their weapons are so ineffective they may as well be civies.
