This section contains a number of methods that will allow you to kill Yuki Yamazaki and Erich Soders without having to change your outfit, enabling you to complete some of the toughest challenges in Hokkaido (their names can be found in brackets)
- Killing Yuki using a sniper rifle, and eliminating Soders without being detected (Sniper Assassin)
- Killing both targets without being detected while wearing a ninja outfit (Silent Ninja)
- Killing both targets in 47's suit without leaving any trace (Silent Assassin, Suit Only)
Killing Yuki using a sniper rifle, and eliminating Soders without being detected (Sniper Assassin)
Begin the mission on the footpath (M8,17) - this means you'll need to wear a ninja outfit. MAKE SURE to deliver a sniper rifle to this location. I recommend Sieger 300, which is silenced and has a few zoom variants (you'll need to make an accurate shot from the distance). Additionally, equip a Disposable Scrambler which will be used to open a few doors in the hospital, and Modern Lethal Poison, used to kill Soders.
Soders should die first, as killing Yuki will alarm the enemies and can hinder your further progress (the enemies may, for example, check the footpath in search for the assassin). Descend from the path and proceed south, making sure to avoid the two guards on the patrol. Reach the side entrance to the hospital (M8,14) and use the disposable scrambler to open the door.
Descend the stairs to reach the morgue (M8,27). Use the moment to visit the security room and destroy the surveillance tapes (M8,26). Sneak through the morgue and enter the stem cell room (M8,29). Once again, use the scrambler and poison the stem cells. Take the lethal stem cell container.
Now proceed to the stairs leading to level 2 of the hospital (M8,30). Approach the stem cell control room (M8,31) and wait until one of the surgeons leaves it. Quickly sneak up to the stem cell pump and place the poisoned container inside. You've eliminated Erich Soders.
Return to the starting location using the same way (M8,13). Watch out for guards that may appear by the eastern staircase, or a patrol that walks along the eastern part of the map. Once you've managed to reach the footpath, take the sniper rifle from the pick-up and approach the edge. However, your task is not that simple - Yuki stopped visiting the garden when Soders was murdered. This means that you'll need to find her when she is near one of the glass walls, e.g. when she visits the restaurant (screenshot above). Make the shot and quickly run to the exfiltration point.
Killing both targets without being detected while wearing a ninja outfit (Silent Ninja)
This variant is different from the previous one, as Yamazaki's body cannot be discovered, and you can't use the sniper rifle. However, the beginning is almost the same as in the previous variant - begin on the footpath (M8,17) wearing a ninja outfit, and take Disposable Scrambler and Modern Lethal Poison with you.
When the mission begins, proceed to the hospital, and sneak to the side entrance (M8,14). This time, choose the stairs leading up, and stand by the door guarded by a single guard. Wait until this person moves north, and open the door.
Use the glass bridge connecting the northern and southern part of the hospital (M8,24). You'll need to be wary, as 47 can be detected one of the employees standing in the garden. Before you proceed south, make sure that the area is clear and hide between the glass walls.
Your target is the sauna (M8,24) - enter the room next to it, and use the panel on the wall to increase the temperature and chase out two patients. Stay in this location, and wait until Yuki Yamazaki appears. Your target will enter the sauna - once she is inside, approach the door and close it shut. Yuki will die, and you can either risk leaving her body here, or drag it to the side room. The door to that room has been locked after your first entry, but you can use a second scrambler to open them again.
Now you need to return to the glass bridge (M8,24) and get across it without begin seen. Once again, avoid the gardener, and the single guard patrolling the corridor.
The next part goes the same as in the previous variant. Reach the security room in the morgue (M8,26) destroy the tapes, and proceed to the stem cell room (M8,29). Wait for a right moment to apply the poisoned cells, which will result in death of Erich Soders. At the end, return to the footpath, and use it to leave the mission area (you can also sneak up to the snowmobile (M8,12)).
Killing both targets in 47's suit without leaving any trace (Silent Assassin, Suit Only)
This challenge can easily be completed by repeating most of the steps from the aforementioned Silent Ninja, with minor changes. As you need to wear your standard outfit, begin the mission in the morgue (M8,28) and stay on the table until the morgue staff returns to their tasks. Take a Disposable Scrambler and Modern Lethal Poison with you.
As previously, begin with eliminating Yuki Yamazaki. Use the previously described path to reach the sauna (M8,24) and lock the door the eliminate your target.
Erich Soders can be eliminated in the same way, i.e. by reaching the stem cell room (M8,29) and delivering the poisoned cells to the pump (M8,31).
BEFORE you leave the mission area, make sure to visit the security room in the morgue (M8,26) to get rid of the surveillance material. Leave the area using the footpath (M8,17) or the snowmobile (M8,12)
