A large portion of Ruk society is based on subtlety, guile, and stealth. Your body has been genetically altered to make you the perfect infiltrator. Your muscles, nerves, and even flesh have been engineered to aid you in your task, and eventually you gain the ability to emit spores that affect those you attempt to sneak past.

Infiltrators are spies, agents, thieves, assassins, or information gatherers. They often wear slicksuits and face-concealing masks (sometimes spore filter masks).
