While traveling throughout the story you must do at least two of the three things mentioned and also be trusted by the NSA above 33%.

3 Qualities of a Hero
-Save Lambart in the last mission of the game by shooting Jamie instead. You will also receive an achievement for saving Lambart.
-At the end of the third JBA headquarters mission do not blame Enrica or allow the bomb to be blown up. Pick the option that allows you to stop the bomb without blaming Enrica. She will then be shot in the head.
-Save Hisham by instead sniping the guard with the red hat in the Kinshasa Mission. You will also receive an achievement for saving Hisham's life.

After doing two of the things mentioned and having a trust level above 33% for the NSA, once you beat the game there should be a bonus mission with yet another bomb for Sam fisher to disarm. Complete this mission to receive the Hero achievement. I found it easiest to kill the guy that goes to the left of the ship then go to the side of the staircase, hold form the railing, and wait for the guy in a red suit to walk outside. Climb over the railing and hide behind something. When he goes to the side with the body then you go inside and sneak up and kill Moss. The bomb is in the same room.

Unlock every single gadget for use in Solo mode. Do this by beating each of the star-marked objectives. Don't worry if you have missed one because you can always replay the mission at any given time.

Just save when you see him and follow him until you get the chance. If you mess up, you can reload and be better prepared.

Tips online- Spy
-Do not go to the same file every single time, learn how to switch between all four of them.
-Do not go the most obvious route to the terminals such a a zipline, because you will most likely meet a drone on the other end.
-Working as a team is extremely important, learn how to take files at the same time and save each other when low on health.
-If your dying you can always go back to your base to get some syringes to heal yourself.
-Be on the lookout for orange lights, they indicate where drones are.
-If you see a drone near you and it makes a beeping noise, you have three seconds to move.
-Turn off a lot of lights and sneak around with the B button, because the Upsilon forces will not be able to track you.
-Remember to use your thermal vision and night vision. Thermal works best in rooms with thin ceiling / floors that allow you to see through.
-Do not stay in the same place for to long because sooner or later there wil be a grenade coming your way.
- If you jump on and knock somebody out stand directly over their body and wait until they stand up. When they are in the proces of standing up throw down a flashbang and move out of range.They will almost definilty punch having no clue what is around them and are in fear of being grabbed. After they are done with the punch stand behind them and now is the perfect oppurtunity to grab them and snap their necks.

Tips online- Upsilon
-Standing in corners is a good way to keep hidden whilst nothaving to worry about being killed.
-You can zoom in with your gun by pressing in the right stick and then even more by pressing up on the directional pad.
-Jumping when theres a spy near you is a good way not to get killed becuase if your in the air then they cannot grab and kill you.
-Always check the most obvious routes at the beginning of the game and each time you kill a spy so as to get a quick kill.
-Stand on a couch or table with your back over the side so that you can send drones withotu haveing to worry about your neck being snapped.
-Assign each person on your team a certain terminal to guard, unless of course all of the other spies are teaming up on just one terminal.-Use the vision provided that senses electronic waves by pressing in the right button on the directonal pad if your having trouble locating the spy that is hacking a file.
- A great way to knock out a spy is to run into him by pressing the RB button.
-A great way to locate a spy is with your detector, just walk around the room and the more it vibrates the closer you are to them.
-If your hit with a flash grenade, remember where you were and try to get your back agianst the wall.
-If your sensor is going crazy and your positive that the spy is hanging from a ledge/window waiting to pull you out and kill you, just zoom in and shoot their hands.
-You have 40 bullets to a clip.. so have some fun with that when trying to kill a spy.

Ways to increase each of the stat levels.
