If memory serves me correctly, you need a certain number of pieces of Intel (hidden in each mission in the campaign). I think that you need 8 pieces. After that, while in a mission press start to open the menu and then I think you need to go to options. Here you should be able to turn on different "cheats" depending on how many pieces of Intel you've found.
It is called "Rescued!!" by Abraham Lass and is available from the iTunes Store.
