I was wondering if people would want a firefight mode to return if 343 were willing to make a sequel to ODST. I really enjoyed this game mode in ODST, but I think it lacked the same feeling in reach. So I figured it might be able to come back if gameplay was similar to the original?
Would be a possibility. 
As long as it doesn’t take away a place for a Halo Wars sequel, I am fine with it.
Doesn’t really belong in the H4 section.
I would also like its own multiplayer, with two or three playlists on it. Just a small getaway from the ‘primary’ Halo game out at the time this so-called ‘Halo 4: ODST’ is to come out.
A sequel to ODST? That’s pretty much Halo 3 canonically.
