GameDynamo - "In addition to main missions in Killzone: Mercenary, the game also has special contracts, which are essentially a special mission mode. Each contract features six special collectibles known as Intel, three from questioning special characters and three from hacking terminals. Collecting them all will net you the silver Fully Briefed trophy. There are 54 pieces of Intel total, and finding them all can be tough. We've created a guide listing all the locations for each Intel in all 9 contracts, so you can find them all and achieve that platinum!"
