Create a mission, then spectate?

[Create a mission, then spectate?]

I'd like to be a spectator in one of the missions I've created. Is there such a thing as a Player Camera or something where I can just watch the battle take place?

I've got a few different battles in a couple areas and it would be fun to watch how each group is doing.

Thanks!

[Joining during a battle]

yea joining in progress just wouldn't work for co-op missions, or doesn't make sense.

For deathmatch or CTF, fine. we had someone join during a game on a CTF map, not sure how he did it.
