What I’m thinking is a Custom Campaign for Halo 4.
Choosing your Character:
You can choose out of lots of characters and choose a name for your character as well. Any species in the Halo Universe.
I do not know a lot about programming but I know AIs would be a problem but you can place an AI to spawn anywhere on the map, you get to choose any specific species with any rank given, also with enemy an ally choosing.
There is flexible audio to use which is sensed by what is said so no misspelling a word or it won’t be said and music in game as well
Cutscenes could be a big problem, but then again you could just go into theater and film a cutscene
So what do you think of this added to Halo 4?
