Hitman 2: Silent Assassin Cheats

When you reach the place where the elevator to the second basement is located, save the game. To do this trick you do not need the lieutenant's uniform. You need Anesthetic. Look at your map and make sure no one is looking towards the elevator and that nobody is in the room except the guard sitting on the chair. Move behind him, knock him out with the Anesthetic (use the whole bottle). Then, take the elevator down. When the guards find him, they will only look around and get back to their positions. This is a safer way to achieve the Silent Assassin rank, as you only fire one bullet (to take out the target).

Start the level by running into the city and move in a general direction to the left until you reach a building. On your map, this is the bottom right building with a silver icon. Go in there and a man will talk to you. After that, walk up behind him (there is no need to sneak), and use some Anesthetic on him. Take his clothes then get out of the building. Then, go to your map. Note: This is very hard to describe in detail because the position of the agent is different each time. Look for the small red weapon pick-up icon. Go in, and a man sitting at a chair will fire two shots in the air, but no one will be alerted. After the intermission sequence, look at your map and find the yellow icon that is stationary (another one will be moving). The stationary icon will be somewhere in one of the two main plaza areas. Wherever the stationary icon is, go into the storage thing under it, and go up the stairs. Sneak up on the man at the window and Fiber Wire him. Take his Sniper Rifle, and take out the other yellow icon. Then, take pictures of the two dead men. Take the pictures back to the agent, and follow your map to the exit.

Earn a Silent Assasin ranking on the St. Petersburg missions. Once you complete "Invitation to a Party", you unlock the M4.
