Shadows of Doubt: General Information about SyncDisks
Let’s go over everything you will need to know about SyncDisks. Why are they so important, and what should you do when you find them?
SyncDisks are consumables in Shadows of Doubt, that give permanent upgrades to your characters. You can have up to eighteen SyncDisks installed, one of each type. You can only select one upgrade tree for each disk.
You can install a second SyncDisk of the same type to choose a different tree, but this will uninstall and remove all upgrades for the previous type.
You can find SyncDisks in high-income safes, and they are also randomly found in the world. SyncDisks are also uncommon rewards for side jobs.
The Sync Clinic staff will randomly sell one SyncDisk, and the Sugar Daddy Sync Disk is unique in that it can be purchased from any Kola machine for ¢r5.
Now that you have a bunch of new SyncDisks take a trip down to the Sync Clinic. You can have them installed there. The Clinics can be found on the map with a DNA icon or in the detective log.
Lastly, now that you have them, and know how to use them, all that is left is knowing how to upgrade them.
To upgrade SyncDisks you need Sync Disk Upgrade Vials. These can be found fairly commonly in businesses and homes. Upgrade Vials can also be purchased from medical vending machines for ¢r1000.
