Wheres My Dog

So I was making the map in Forge with my friend and it requires a specific game type to work with the whole thing properly. But sadly, Halo 4 lacks the awesome gametypes that they had in reach. My Personal favorites that are no longer with us are Infection and Race. I do realize that this is most likely temporary but I would like to know when 343 Industries are going to update the game types for Custom Games at least. And yes, I do know that Flood is basically Infection. But you can ONLY be a Flood which is disappointing.
