Complete the "Defeat Nasri's Guards" objective and remain in that room. Notice that there are three sets of stairs. There is a door behind two of them and another with a table across the top. In front of that table is an random ammunition collectable. This collectable will respawn after approximately thirty seconds.
At the end of the mission, you can find two ammo collectibles in the garden on the north and south sides. They will respawn after you move back to the doors.
You can customize your character's appearance again by going to the bathroom.
Clear out the henchmen that first appear, then run to the gate Darcy is overlooking. Hide behind the packing crates next to the gate. You can get a clear shot at Darcy from there. Shoot him from there and his grenades cannot reach you.

  Xbox 360  Make Steven Heck really dislike you. Do this by generally being professional, telling him to "shut the f**k) up", and taking safer "no casualties" approach to missions. Also ignore his request for a favor in one of the missions. Visit him last in the Taipei missions, and act professional. He will be annoyed that you saw him last. Then select aggressive, threatening, impatient, threatening, and aggressive. You will then get an email once you return to the hideout, and then can tell him to "shut up". In the Hotel mission, choose discreet. Steve will call you a "wet blanket" and give you a negative reputation. Do not delete his file from the servers another negative reputation. When intercepting the assassination plans (in the conversation before the short intermission of you hopping on the bike to leave your hideout), choose professional.
