In multi-player mode, select either Xbox Live or System Link. Go to Co-op Challenges, and select "CodeName: Onyx". Choose Mission 03. If you chose Xbox Live, make sure this is a private game so that you can host your own room. Press X to start the game. Go through the double doorway to the right of the gadget stock, then turn right at the stairs and walk up. On the wall will be a Comcast sign. Turn and go up the stairs once more and enter the room with the number 2 on the wall to the left of it. Once in the room, turn right to the first open window. Run all the way to the end of the walkway and jump to the landing directly in front of you. Climb up the ladder, stop, turn right until the camera is facing the building you just came from. Look up to see a huge Comcast billboard. Click the Right Analog-stick to view it from your goggles. D-pad Up zooms in, while D-pad Down zooms out.

When you have a choice to shoot Lambert, aim for his head, eye, mouth, nose, or anywhere else above his shoulders. Somehow when he hits the ground he can still manage to talk.

Make sure you have a flash and a frag grenade and full life. There are a lifebox near the door outside of Emile on the right wall. Go outside to Emile and an intermission sequence begins. When it is done, on your left may be a laser beam. Wait for it to go off. When the laser goes off and Emile is done shooting (he will begin again), roll to the next chair or bench. Wait until he is finished shooting again. Continue doing this and go up for the fence/rail. Jump onto it. Go down from it and you now must take Emile out. Walk away for one or two seconds, and make sure you can drop the flash grenade near Emile. Shortly after it is dropped, put your frag grenade in the same place. Emile will not see you drop it and will be defeated. Then, read the computer and defuse the bomb. Note: Take your time.

If you are going to kill Hisham, wait until he is down in the parking space. Kill him and pick up his body. Walk to the back of the red car and put him in the back. Press [Place Charge] and stand back. Detonate it and the "Opportunity Objective complete - Dispose of Hisham's body" will appear.
