No boom skull or bandana skull for H1

Games Halo: The Master Chief Collection
#1

My Laso campaign playlist for Halo 1 shows 13 skulls active, with a 13.16 multiplier. Boom skull is included naturally. But when I go to campaign for Halo 1, boom and bandana are notably absent from the skull choices for me :frowning:

There are only 10 skulls to choose from. Where are the remaining three?! Please help!

Did you acquired these skulls on the campaign? I would review any youtube videos on how to acquired each skull on H1.

There was some skulls that came in as free with purchase of MCC I believe back then as well.
