Irene

Trade in for a shield. Stack your team at the door across from the box, and proceed to the door at the other end, on the right of the box. Equip your shield and thermal goggles. One foe awaits you on the left side of the stage. Take him out, and prepare for four more on the right side. When they�re all focused on you, unleash your team to flank them from the side. Proceed toward the waypoint for another tough skirmish.

Keep your shield/pistol out and set Jung to hack the computer below. Get into position to the right of the console and pull up your shield, because the battle will be brought to you after your team starts working. They will rappel from the right and left frequently, with reinforcements to deal with from the sides of the map. Without moving far from your position, take them out as quickly as you can. Their objective is to destroy the computer, not to kill you, so don�t leave them alive for too long. Thermals help a great deal in this section. If Michael falls, remember, you�ll have to unequip your shield in order to heal him, so do it if you�re absolutely sure it�s clear. After Jung delivers a short exchange of words, head upstairs on the right side with extreme caution. Kill two more enemies before proceeding. Toss a grenade from the middle of the stairway to the entrenched terrorist�s position for an easy clear. Head upstairs, past the large set of windows, and towards the metallic barricaded door for a checkpoint.

Your team will automatically regroup, so head through the newly opened door and prepare to take down Irena. Follow a few hallways into another assault. Fight through a few waves of resistance from the doorway, firing through the window panel on the right, as well as the doorway on the left. Send your team in to mop up the few hiding in spots unattainable from you position. When cleared, follow the stairways up to the second floor to kill Irena and to trigger a conversation. When she finally dies, take her Glock-18 pistol (it�s a one of a kind, and this is the only place to receive this awesome automatic pistol for future use). Enter the elevator to activate the final chapter of the game.
