Rolling from a Sam Fisher challenge to the Cross Bow challenge I feel was a great missed opportunity to have players look forward to playing through all of season 2. Why not have all proceeding challenges related to Special Operation 1? All challenges should have Sam Fisher involved one way or another and the final challenge prior to the release of Spec Op2 should be a big finale mission/challenge. What ever theme is set for Special Operations 2, all challenges would be related to the theme with the final challenge as big finale. Then obviously the same for Spec Op 3 & 4.

Something to really consider for season 3 since you didn't take season 2 down this path.
