Firefight with your own Custom Characters.

After playing Mass effect 3 I think it would be pretty awesome, not only would you customize your Spartans look, you would customize his weapons, class, and perks/unlocks.
Also calling in AI buddies Via air drop and things along those lines would be great.

I think if they don’t do something like this they’re missing an opportunity.

Heavy Spartan, Sniper, Rifleman, Assault, and Stealth style. Seems like it would work to me, and Elites could get a similar thing depending upon their role in the game.

I feel like this would not fit into firefight because
A. It is a first person shooter so that face you tried very hard making would most likely not be seen by you alot unless in theater mode.
B. Mass effect has a story which revolves around your character something firefight lacks.
I’d like to say that i’m not trying to shoot your idea down just disagree disrespectfully.
