O.S. Upgrade Machine
O-S Upgrades
O/S Upgrades are character stat boosts in System Shock 2.

In-Game

O/S Upgrades are granted to the Soldier by special upgrade stations, identifiable by their unique light blue display. O/S Upgrades give special statistical bonuses and abilities which are unattainable otherwise. The Soldier can have four O/S Upgrades installed at a time. O/S Upgrades are permanent, and cannot be uninstalled. O/S Upgrade stations are exhausted after a single use.
