Splinter Cell Double agent walkthrough?

Spend some time on the game, it is VERY short if you don't do everything in it.I recommened replaying the end of the game over a couple times, there are many ways to complete the mission. If you find yourself bored during the missions, try to go into the restricted areas. You will then be able to get medical files, retinas, and fingerprints that are needed for later missions.
