Psycho-Reflective Screen or Psi Shield is a Tier One defensive Psionic Power in System Shock 2.
Overview[]
This Power provides 15% defense against damage of almost all types. The only excluded sources are radiation, toxins and drowning. Its duration depends on the player's PSI and equals 30 seconds × PSI + 20 seconds. Note that Overloading this Power does not affect it in any way!

Analysis[]
- It is one of the first Psionic Powers the player is likely to unlock due to its low requirements and wide usefulness.
- This Power is extremely practical because it affects all types of combat damage and almost all of non-combat.
- Defense given by the Psi Shield stacks with that of physical Armors and the WormMind Implant.
- Psi Shield's defense also accumulates with other defensive Psi Abilities (one or more):
- Psycho-Reflective Aura for defense against most types of damage
- Energy Reflection for protection against energy-based damage
- Other defensive Psi Powers complement the Psi Shield:
- Neural Decontamination vastly shields against radiation absorption
- Neural Toxin-Blocker blocks all toxin intake
- It should be cast before all other Psionic Shields, as it lasts the longest.
