To defeat Emile, have a flash and frag grenade with full health. There is a lifebox near the door outside of Emile on the right wall. Go outside to Emile and an intermission sequence begins. After it is over, on your left shoudl be a laser beam. Wait for it to go off. After Emile is done shooting, roll to the next chair or bench, and wait until he is finished shooting again. Continue doing this and go up to the fence, and jump onto it. Go down from it and you now must take Emile out. Walk away for a few seconds, and use the flash grenade on Emile. After dropping it, use your frag grenade on him. Emile will not see you drop it and you will kill him. Then, read the computer to defuse the bomb.
