OSA

The OSA (or rarely O.S.A.) is one of the principal organizations in System Shock 2.

The OSA is a newer branch of the UNN, grounded in the newly established Psionic Disciplines, and already has acquired a rather dark reputation as a group of “spooks”. Officially, OSA is a research branch of the UNN, but rumours claim that it also acts as UNN’s “black ops”.

OSA Agent is one of the three classes selectable by the soldier.
