Battlefield 3 Semper Fidelis walkthrough: Learn how to survive the speeding train, find Viper Squad, and master weapon use.

Walkthrough
  1. 1
    You will land on a speeding train and enter through a window. Pick up the gun immediately.
  2. 2
    Aim and shoot the two gangsters in front of you as soon as you see them and continue forward.
  3. 3
    Crouch under the fallen debris. Be careful as there are three more enemies in the next compartment. One is straight ahead, and the other two may take cover (press the cover button to crouch behind walls or objects) behind seats to the left and right.
  4. 4
    After killing them, move up and take the M1014 gun that was used to bar the door.
  5. 5
    Hit left click when prompted, go to the door at the other end, and hit "e" when asked.
  6. 6
    Outside, hit space once. When you are shot at through the window, continuously hit space to climb up the side of the train.
  7. 7
    As soon as you are on the train, go into prone (lie flat on the ground).
  8. 8
    Keep looking to the left in front of you. You should see one enemy come up, and another shoots at you from the same side but from a bit further away.
  9. 9
    If you are not in prone, crouch or prone as soon as an explosion takes place and keep moving forward. You will drop into the train.
  10. 10
    Be ready for more enemies who will come in from the door in front of you. You will not be able to see all enemies.
  11. 11
    Stick to the left or right wall, whichever has more cover (objects that block enemy fire), and if you sense an enemy, shoot. There is plenty of ammo.
  12. 12
    Keep moving and be ready for more enemies. Eventually, you will reach the objective.
  13. 13
    Operation Swordbreaker: After the cutscene (a non-interactive cinematic the game plays automatically) (an in-game cinematic), you will exit a van. Follow your squad to the rendezvous point.
  14. 14
    After a brief moment, follow your squad to a dangerous part of town. You should see a "follow" tag on one of your teammates.
  15. 15
    It is imperative that you always keep the "follow" marker on your teammate in sight to know where they are.
  16. 16
    This mission requires attention to detail regarding enemies in large areas.
Tips
  • Enemies will not know where you are if you move from cover to cover, unless they saw you moving, giving you the element of surprise.
  • When a move icon is on the minimap (the small circular map in the bottom-left corner of your screen) (a small map display), stop shooting and go to the indicated location from cover to cover.
  • If there is a follow sign, follow from cover to cover. If you kill an enemy, another will replace him; you do not have infinite ammo, but enemies will keep coming.
  • If there is no move or follow sign, you have the area to yourself and need to clear it, but it is sometimes wiser to run away, especially if a helicopter is waiting to extract you.
  • In all missions, soldiers pick up mission-specific weapons at the start. You have these weapons for a reason, so it is best not to switch them unless you are out of ammo. Even then, look for an ammo dump before ditching your weapon. A shotgun or SMG cannot replace a sniper rifle, especially one with an IR scope.
  • Be careful, be ready, and be vigilant, as danger can appear at any time.
  • When enemies are present, stick to the left or right wall for cover. If you sense an enemy, shoot.
  • If playing on HARD, be aware that enemies are more dangerous.
