Recent developments involving strongly coupled superstrings are discussed
from a phenomenological point of view. In particular, strongly coupled
E8×E8′ is described as an appropriate long-wavelength limit of
M-theory, and some generic phenomenological implications are analyzed,
including a long sought downward shift of the string unification scale and a
novel way to break supersymmetry. A specific scenario is presented that leads
to a rather light, and thus presently experimentally testable, sparticle
spectrum.Comment: 22 pages, 2 figure
