Psycho

A unique delivery system filled with strange and unknown chemicals, probably of military origin. It is supposed to increase the combat potential of a soldier.

Fallout 3
Psycho appears to be a form of injected drug, which, considering the large serum canister next to the needle, suggests that large quantities are needed to produce the effects. Psycho is very addictive, only taking 3-4 doses used in rapid succesion to result in addiction.

It has been suggested that the way the drug works is to give the soldier a better perception of his/her environment, allowing him/her to target weaker areas of a target than before.

Locations
