Exotic Particles are one of the three types of Exotic Substances. They relate to the Etheric Science speciality, and tend to interact in interesting ways with devices that store or consume energy in the form of Charges. Exotic particles of one kind or another can occasionally be found in the environment, but require a scanner to locate and collect.

Exotic Particles can be physrepped with some kind of containment device, which can hold multiple samples of a single type of particle. Containment device physreps should be no smaller than a deck of cards, and would typically be about the size of a jam jar. Depending on the faction technology style, a containment device could be a large crystal, a series of metallic tubes with lights and buttons on it, or a panelled cube with various plug sockets on it.
