Humans are the remainder of the species that did not become irradiated living in the toxic lands after World War III.
Those few who survived in the midsts of the Cities or through the use of special protective suits whilst in the wastes class themselves above all other mobs in the world.
Most NPCs in game are human, traders, employees of the factions etc.
Interestingly class choice has some bearing on your characters status.
- Gentanks where bred as a genetically engineered soldier to fight in the Great war, strictly speaking they are not Human.
- Psi Monks, decendents of humans who sought shelter in caves, centuries later found as troglodytes with telekinetic psi powers they emerge to once again move amongst humankind.
- Spies and PE's are human citizens.
