: 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???

Your math is incorrect I think. Halo 2 by itself with all DLC included has 25 maps. Halo 3 has 24 which is 49 maps. My understanding is that Halo 1 PC and Halo 4 have even less.

: 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...
