What is your favorite Map?

My favorite map of all is Halo 2s’ Coagulation.

Blood Gultch in Halo CE

Halo 4: Rail/ abandon halo 2: lockout/ warlock

Ragnarok/Valhalla

haven (h4 only)

It appears as if this thread was created to include all the games, not just Halo 4. If this is the case, then this is supposed to be in General Discussion.
To answer your question, OP, my favorite map is Halo: CE’s Ice Fields.

Forge Island. It’s very quite and simple.

Perdition

Ragnarok

Haven, Exile, or Ragnarok
