General objectives of the stage: Courtyard is the first of as many as seven stages Hunter and Hunted mission. The main objective of this stage is to pass the titled courtyard guarded by police officers in order to get to the Vixen club.
Start with the linear path, passing by a vagrant who is no threat for you. You can also look around for a bottle or a metal pipe. Stop only when you reach a corridor with two cops. Regardless of chosen difficulty level you should stay away from them because sneaking past them might be very risky.
If you play on one of lower difficulty levels, there will be one additional opponent in the area. You can find him inside a left room, behind some kind of a shrine.
On higher difficulty levels you have to expect one more policeman here, patrolling the corridor adjacent to the one with two cops mentioned earlier. I suggest neutralizing one of described officers, so you can obtain Chicago policeman disguise and make it easier not only in the rest of this stage, but also in the next one.
Ultimately you have to reach to the stairs shown on the above screen, leading to the courtyard. Note - on higher difficulty levels you might expect a single cop walking towards you. If this happened, hide in the side room and wait until he walks past you.
Move to the courtyard and spend some time to get to know with the situation. Also in this case, the selected difficulty level plays an important role - on lower difficulty levels there will be only few enemies in the area but on higher difficulty level you'll have to face a fairly large group of them. I suggest starting with moving to the police car parked on the left.
In the area you can find first evidence. It lies on the hood of the police car parked in the center of courtyard - the one with the engine off (screen above). In order to get to the mentioned secret you have to use a disguise and Instinct, but you can also throw a bottle or any other item to distract policemen.
Do not try walking to the passage guarded by a single policeman. Instead of this carefully move to the left, stopping at a small wall (screen above). Depending on the difficulty level, you'll see one or two cops in front of you.
Patiently wait until officers turn around, quickly jump over the wall and head straight ahead. Sneak past cops, reaching the edge shown on the above screen. Climb down as fast as you can, reaching a safe place near the stairs. Now you have only to unlock the passage to next stage.
