Psycho (Fallout 3)

Background
In the Operation: Anchorage add-on, the origins of the chem are explored in more detail. The American field doctor in the simulation can give the player psycho before combat, and a holodisk can be found that details the creation and use of the drug. It is also revealed that it can cause anger issues and other dangerous, long-lasting side effects.
