Infection gamemode?

I'm hoping the gamers in Bungie are as excited for Evolve like a lot of us are. Other than the sword arm that 343 used on its infected models I liked the fact they finally gave Halo fans a Flood Zombie to play as. I could see Hive models being used for Infected. Hopefully there's some sort of public event where players on one side get hit with something that changes them into super powered Hive warriors. The other side has to put them down to free them or they get added to the infected if they lose the battle. If not hopefully Bungie placed in a forge of some type so the community can forge in their own public events and criteria. I'd also like to see a Juggernaut game mode where players get control of some boss. All in all if it's not there you'll find it in Halo5 or in Evolve just little later on.
