Synchrozine is a crucial consumable item in Observer, used to replenish Daniel's Synchronization meter. While not a 'side quest' in the traditional sense, actively searching for Synchrozine is an important activity that directly impacts your ability to survive and investigate. You'll find Synchrozine vials scattered throughout the apartment complex, often in bathrooms, medical cabinets, or hidden in drawers and on shelves. Use your EM-Vision (1) and Bio-Vision (2) to highlight these items, as they can sometimes be difficult to spot in the dark environments. Each vial restores a portion of your Sync meter, allowing you to continue using your vision modes and endure the psychological strain of neural dives. It's wise to always keep a few vials on hand, especially before entering a new neural dive sequence, as these are the most demanding on your Sync. Don't be afraid to backtrack to previously explored areas if you find yourself low on Synchrozine, as new vials might appear or you might have missed some during your initial pass. Efficient management of your Synchrozine supply is key to a smooth playthrough.
