Intelligence items are various kinds of objects containing  information which could be useful. However, when actually reading the contents of such an item, it frequently appears to be a simple joke. Examples of intelligence items are:

- Note

- Letters

- Loose files

- Envelope

- Dossier

- Suitcase

- Blueprint

- Film

- Tape

In both games the amount of intelligence items will determine your "rank". In The Operative: No One Lives Forever the amount of intelligence items collected per mission will determine your overall rank for this mission. In No One Lives Forever 2: A Spy in H.A.R.M.'s Way collecting intelligence items will yield Experience Points (XP) and your rank is determined by the amount of XP collected.
