Ghostwire: Tokyo players will unlock side missions after cleansing Namita Shrine during the "A Maze of Death" main story mission in the game's second chapter. There are 42 side missions in total, though players will only have access to two of them right away. The first of these is called "Deep Cleansing" and requires players to investigate a water-related mystery in order to lay a restless spirit to rest.
As players will soon discover, side missions in Ghostwire: Tokyo are marked on the map by green circular icons. The one for "Deep Cleansing" is relatively close to Namita Shrine, so, after cleansing the rooftop Tori Gate there, players should make their way back down to ground level and head towards the green map marker for "Deep Cleansing," which is to the southwest of their current location.
How to Begin the Deep Cleansing Side Mission
Upon arriving in the area with the map marker, players will find themselves outside a building with a lot of Crystallized Ether nearby. After heading inside, they should check the area near the door for some consumable items and absorbable spirits before making their way upstairs. Through the door to their right, players will find the spirit of an old man concerned about water and should speak with him to begin the quest.
Where to Find the Pooling Water
After talking to the old man, KK and Akito will deduce that they need to find a place where water is pooling, which means heading back outside. Thankfully, finding such a place is relatively straightforward, as the map marker updates to guide players northwest towards a nearby bathhouse. Before they can get inside though, players will first need to destroy a corrupted tree, which can be accomplished by locating its core using KK's Spectral Vision (press Square to activate) and then hitting it with either the bow or Ethereal Arts to destroy it.
How to Complete Deep Cleansing
Once inside the bathhouse, players should head through the door in the back right-hand corner of the sento, where they'll need to destroy another corrupted tree to reach a second door. This one will lead to a long corridor, at the end of which is a third and final door. Opening this one will transport players to a mysterious water-filled location, where they'll need to defeat four waves of Visitors in order to cleanse the corruption.
After all of the Visitors have been defeated, players will be returned to the bathhouse. They should then head back down the corridor and through the newly accessible door in front of them. It's at this point that they'll receive a notification letting them know that the quest has been completed, as well as the "Problem Solver" trophy/achievement if this is their first side mission. Before leaving the bathhouse, players should be sure to absorb all of the nearby spirits, which should be enough to help them to gain a level or two.
Ghostwire: Tokyo is available now on PC and PS5.
