Game modes yet to be implemented?

Some game sounds in here that are for well known game modes not in Halo 4

This doesn’t prove anything. Reach had the VIP announcer clups, but there was no VIP gametype until a few weeks before Halo 4’s launch and it was modded.

They are as they are named; unused.

I’m not trying to rule out any gametypes in the future, as it more than likely will happen eventually.

they are adding new gametypes in little steps

they’re adding free for all soon
