For Modern Warfare II and Modern Warfare III players, timed-exclusive MWII Operators and/or Skins are not available if they haven’t been unlocked or purchased. This mainly relates to Battle Pass Operators and Skins, as well as BlackCell Operators and Skins.
Example: The Operator Io (shown above) was included in the Season 04 BlackCell offering. If players didn’t obtain her then, they will be unable to obtain her Base Skin now.
