I know this may be a noob question, but I haven’t been on Halo in a long time so I’m unfamiliar with how the playlists are now. If so I’ll most likely be making a come back.
I’m assuming you mean extraction, conversion is a community made twist thats never been in MM… to answer: is extraction in halo 4 MM… it is, but ONLY as a RARE option in throw-down, so if throw-down aint your cup of tea or you cant be bothered sitting through 5-6 slayer games to get one extraction match, sorry, but customs are your best bet…
only in throwdown as far as I know.
I appreciate the reply 
hopefully one day Conversion will be in matchmaking. It reminds me a lot of Invasion from Reach.

I 2nd that.
Made a thread in the Matchmaking section not too long ago. Think someone from 343 replied…
Unfortunately, Conversion is not in MM.
The only times I ever go back to Reach is to play Invasion. One of my most favorite gametypes in Halo.
Conversion, when THFE announced it, basically brought Invasion back in Halo 4, and made me super happy. I was really hoping 343i would put it in MM.
And then, 343i has an interview with one of the creators of Conversion. I was really hoping that at that interview, 343i would’ve said something along the lines of “Conversion is being planned to be put in MM, and we’ll let you know when/if it happens.”, but alas…
I really hope 343i brings Conversion into MM one day. Heck, I think they should have the Dominion playlist, rename it Squad Battle or something, and have Dominion, Lockdown, and Conversion in it. That would be one the best playlists in Halo 4 IMO.
