Run down the road that the Agency's pickup is down, heading west until you see a man wearing a tuxedo walking towards you. Knock him out with the Anesthetic and hide his body around the wall. Take his clothes and grab the invitation. Go to the front gate and show the guard your invitation. He will let you in. Go through the front door and go into the ballroom. Wait until General Zuphikov walks past the maid's room, then kill him with the Fiber Wire. Drag his body into that room. It is the one next to the maid's room, closest to the ballroom door. By now, the German ambassador should be walking up to the office on the second floor, alone. Follow him, and when he gets to the office, knock him out with the Anesthetic. Take his combination and use it to open the safe. Take the briefcase and go back downstairs. Walk out the front door and go through the front gate. Run back to your boat, and you should complete this level with a Silent Assassin rank.
When you start, chloroform the waiter. Take his clothes and his key. Go to the agency pick-up and get the poison. Enter the right gate entrance (not the center one). Enter through the garage door. Carefully walk past the guards through the hallway and go into the kitchen. Get the champagne glass. Exit through the first door on the left. Go to the top of the stairs on the left. Put the poison into the glass. Enter the main room and wait for the general. Walk up to him and he will take the poisoned glass. He will cough and run into the bathroom. Follow him and watch him vomit to death. Then, carefully go upstairs and enter the secret entrance to the second floor balcony (go up the left staircase, go in south left south door, walk into the wall right in front of you, then open the door). Be careful, because there will be guard, a W2000 sniper rifle and a guest's clothes. Quickly put on the clothes and leave without the guard seeing you. Ignore the sniper rifle. Buy now the Spetsnaz has held up the ambassador. Quickly go to where the agent and the ambassador are located. Go into the connecting room. Sneak in behind the Spetsnaz agent and Fiber Wire him, slit his throat, or shoot him in the back of the head with the silenced 9mm; make sure he dies quickly. If he is not already dead, chloroform the ambassador. Get the suitcase and leave through the front door, then exit through the gate you first entered (not the center one) and proceed back to the boat.
Your objectives are to eliminate the general and to retrieve the suitcase. In this mission, there is also a Spetnaz agent trying to retrieve the case. Do not eliminate him unless he tries to kill you or gets to the suitcase before you. If you kill him, you will not get the Silent Assassin rank. When the mission starts, immediately run up the stairs and take out the Fiber Wire. Sneak up to the waiter who is smoking. After you strangle him, drag his body and hide it behind the nearby dumpster. Take his clothes and a key then run up to the open road. Check your map and you will notice the agency pickup is hidden in an alley. Run towards it. Do not worry about being spotted, as you are in disguise. Pick up the poison and anything else you need. Then, check your map and you will notice that a guest is arriving on the far end. Run towards the guest and hide in the alley behind him. With perfect timing, you can strangle him. Hide his body without being noticed. This may require a few attempts. When you finally succeed, take his tuxedo and invitation. Then, walk towards the gatekeeper. With your invitation, he will let you in. Walk towards the entrance and enter the building. There will be two staircases and a huge door which leads to the party, However, instead look for a small side door which leads down to the kitchen. Go down and through the kitchen, ignoring the cook. Then, pass the bodyguards and look for a small room on the side. Go inside and you will find another waiter's suit and a 9mm pistol with ammunition. Put on the suit then go back to the kitchen. Take a champagne glass and go up the stairs. Without anyone noticing, poison the glass. Your objective is to kill the general and retrieve the suitcase. Go into the party hall and walk towards the general. He will take the glass and drink it, then run outside. Your first objective is now complete. Now, look for the ambassador (marked as a VIP on the map). He will go up the stairs. Follow him. Then, follow him into a room with a safe. When he opens the safe and turns his back, strangle him and take the brief case. Hide it in any other room on the same floor. Then, run back all the way tp the kitchen without being noticed. Go into the room where you found the waiter's suit. Change back into the tuxedo then rush back into the room where you hid the case. If you run into any trouble with the Spetnaz agent, eliminate him with the silenced 9mm pistol and hide his body. Take the case and rush out of the building without being noticed. Run back to the starting point of the mission to end it.
