Not sure what you said...
anyway, in order to get the achievement you must complete ALL missions on Perfect difficulty (the order you do them doesn't matter).
You have to play at least once, either by your own or with a partner.
You must play it two more times on Dark agent difficulty (which you'll unlock after you've completed Perfect difficulty), both alone and with a partner.
