Will that medal be incorporated again? 
or at least voiceover
If “Unfrigginbelievable” was in the original game then it’ll be in the MCC.
edit
If you meant for H2A then I would assume so because the medals we’ve seen so far in gameplays suggest they’re incorporating Halo 4 medals.
About 99% sure it’ll be there.
It would be unfrigginbelievable if they didn’t add it!
