Assassin's Creed Chronicles: China

In order to Shadow Gold you must pass a guard undetected and not engage in combat, including taking enemies down via assassinations. Each guard has a line of sight which you can see. When it is white in colour they are unaware of your presence, when it is yellow that are aware of a noise or distraction nearby and when it is red they are aware of your presence and location. You must get past a guard without their line of sight turning red or yellow. It must be white when you leave the area the guards are in. There are numerous ways to get past a guard without them detecting you, these include:

Whistle:

To use you whistle, hold then move the to the right to increase the area in which the whistle can be heard and then press to perform the whistle. Once the patrol guard has moved sneak past his line of sight without being detected.

Firecracker:

Noise Dart:

The noise dart is unlocked at the end of Memory Sequence 1. To equip it press , then hold and move to aim it. Press to throw it and distract the guard. The guard will be alerted to the area in which you threw the dart and once he is distracted, sneak past him.

Hiding in the shadows:

Often you will come up behind a guard and you can hide in the shadows by pressing if there is a dark area behind them. Once the guard looks the other way you can then run past him and avoid his line of sight and remain undetected.

When you successfully perform one of the above mentioned methods to get past a guard, a notification will appear in the bottom right hand corner of the screen informing you that you have achieved a Shadow Gold. Once you have done this 30 times, the trophy will unlock.
