Very sorry if this is a repeat question from somewhere. I played through Reach once last year and at some point played against my brother in slayer mode over Live. I haven't played it since then, but when I brought it out to play it yesterday with some in-laws we could not find the "traditional" slayer multiplayer that I remembered and which I've played in past Halo games.
I see that there seems to be something up with deleting some multiplayer options, but I don't know anything about that (can you recommend a good, straightforward place to read about exactly what's going on?) or whether this is related to that. Again, apologies if this has already been treated elsewhere, this is my first time venturing on the forums. Many thanks.
