Custom Games and VS Firefight for Halo MCC and maybe Infinite when that comes out.

Have you ever wanted to have a good game of VS Firefight but can't because you have no friends? How about that one custom gamemode you adored playing, but now can't because the people you last played it with haven't been on in 4 years? Good news, we can help you find a lobby! Bad new, we can't get those friends to come online again.
