In Hitman 3's Chongqing level, one of the more confusing challenges to unlock is "A Shock to the System," which is obtained by eliminating Imogen Royce via electrocution. While the photograph in Hitman 3's challenge menu of a water cooler may give players a clue as to how to complete the challenge, players will require a specific item to successfully electrocute the target.
There are two items in the planning menu that players should be equipped with before starting the level. The first item is an "ICA Remote Micro Taser," which allows players to detonate a small electric charge from a distance and is unlocked by reaching mastery level 2 in Berlin. The second item is the "Lockpick MKIII".

Starting from the riverside walkway, head towards the main street and down the ramp until an internet cafe is visible on the right. At the cafe, use the lockpick on the door and proceed to the back room where the player will find a screwdriver and a street guard disguise.
Once Agent 47 has been disguised, proceed to the back entrance of the internet cafe, which will lead to an open courtyard with two guards patrolling. Because the player has the street guard disguise, the two guards will pay no attention to Agent 47.
On the right-hand side of the courtyard is a small hidden access shaft that leads into the underground laboratory. To open the accessway, enter the code "2552." With the shaft now open, climb down the ladder and proceed to the first visible ventilation grate.
Normally these grates can only be opened via the USB dongles found throughout the lab, but because the player has a screwdriver in their inventory, the grate can simply be unscrewed. After climbing through the vent there are 3 key points of interest that players should take note of.
Players will notice a guard resting on the left. To the right, there is a surveillance camera, and directly in front of the player is a scientist in a control booth. The first step is to stealthily open the door to the control booth and use 47's camera to hack the windows on both sides so that nothing can be seen through them.
After the windows are hacked, players can now subdue the guard who is resting on the left. Due to the number of scientists in the area, players will have to carefully assess the optimal time to subdue the guard, as they can be easily spotted.
With the guard subdued, players can now assume the disguise and dispose of the body. To dispose of the body, players will have to carefully drag the guard across the hallway into the closet by the surveillance camera. This can be extremely tricky, so it is recommended that players make a manual save before attempting.
After the guard has been disposed of, head upstairs to the water cooler in the analysis area. Once at the location, subdue the employee in the adjacent office and hide their body in the nearby closet.
The player should now head to the water cooler and drop the micro taser. Players need to be sure they drop the device, as tossing the device may cause one of the nearby office workers to investigate the noise. With the device now in place, wait for Royce to make her way to the area, and once she is nearby, puncture the water cooler with the screwdriver to cause it to leak.
When Royce reaches the water cooler, detonate the micro taser, which will unlock the challenge. If the player has followed all of the aforementioned steps, they will also be eligible for a silent assassin rank after eliminating Hush later in the level.
