S.H.I.E.L.D. Rank

S.H.I.E.L.D. Rank is a level which increases with earned XP, which is given out as game tasks are completed. Currently it unlocks basic features and gives out Iso-8. More features are yet to be implemented. Previously, the ranks went from 1 to 125. As of November 9, 2017, the maximum rank was raised to 200, and what could be done to gain experience points changed.

As of the November 9, 2017 update, XP can only be gained from completing an activity for the first time ever in the game or from spending covers, either by recruiting new characters or by adding covers.
