Introductory information
There are 42 secrets to find, they are called secret service data. In every mission there are three objects to find. The only exception is the stage called G.D.C.C., because there are no interactive scenes.
Every time you find a secret, the game saves the information so even if you die before completing the mission or reaching a control point, you won't have to collect the secret again.
Finding secret service data is a part of the description of completing the mission for a single player (green), so I suggest you use this chapter to find the secrets you have missed quickly.
The game allows you to check current progress connected with finding secret service data and you can do it from the main menu (campaign and INTEL LOCATION).
