Now I am sure there will be many of these in the future, but what things would you like in halo 5 forge, Honestly with all they have done with it in MCC, All I could say is drivable scarabs, dynamic weather and the possibility of placing down AI that attacks and defends sort of thing, with that the amount of things the community would create would be exceptional
I would love to see a firefight forge option which allows you to create spawn zones for AI. A little more In depth then just spawn and place AI.
