55 multiplayer maps on shipped on disc. Halo 1-4
48 multiplayer maps released as DLC. Halo 1-4
8 PC maps shipped on disc. Halo 1 and 2
6 Halo 2 remakes. Halo Master Chief Collection

57+48+6+6= 117 Serious missed opportunity for the official Master Chief collection.

Cut Tombstone and Desolation we get 115
Cut the 6 Halo 1 PC maps we get 109

>commencing speculation

Cut the original versions of the re-imagined H2 maps we get 103
Cut Halo 2 Vista maps (as it was also PC related) and we get 101
Cut Cold Storage (as it was never really in matchmaking) and we get 100
Cut Mythic II Map Pack (as it was part of Halo ODST) and we get 97

What else is getting the ax???

Also, 93 Multiplayer + 8 Spartan Ops maps(not counting the 4 reused single player maps) is over 100, but I would have much rather had ALL the glorious Halo multiplayer to bask in. All 117...
