Walkthrough
Wait for the cutscene to finish then walk forward and melee the enemy in front of you. Get up and go up the stairs to the right. When you are told to, headshot the person leaning over the balcony. Now go to the door marked breach, press use to breach. Everything goes into slow motion. Here, you can easily take out 4 enemies with 4 shots for an achievement. After breaching has finished, the slow-mo ends and normal combat begins. It should be a very easy fight. After the hostages have been released, go up the stairs, take note of a shelf to your left at the top of these stairs, this contains Intelligence.
