The Psi Hypo is an item in System Shock 2. The Psi Hypo instantly restores 20 Psi Points (24 with the Pharmo-Friendly O/S Upgrade) on Normal and above difficulties or 30 Psi Points (36 with the Pharmo-Friendly O/S Upgrade) on Easy difficulty.


The Psi Hypo contains a potent cocktail of tension relievers, dopamine inhibitors, and circulatory stimulators. This mix of side-effects can be habit forming.

The chemical cannot be copied through Molecular Duplication, to protect TriOptimum's monopoly on the substance.

Strategic Analysis

  • There are some Replicators that sell Psi Hypos at a price below normally encountered, especially when hacked.
    Namely, these are located at the Engineering Deck near the elevator and at the Recreation Deck near Barracks.
