What will you play first when you get Halo 4?

Matchmaking, Forge, Campaign or Spartan Ops?

I will probably play a few campaign missions. Then jump into matchmaking then more campaign. Later on… Spartan ops. Then I will finally check Forge

I usually play Forge first in order to get to grips with all of the weapons, just so that I can get a feel for them before actually using them in combat.

I never touch matchmaking before I complete the campaign on Legendary.
