  We construct N=1 supersymmetric field theory in 4+2 dimensions compatible
with the theoretical framework of 2T physics and its gauge symmetries. The
fields are arranged into 4+2 dimensional chiral and vector supermultiplets, and
their interactions are uniquely fixed by SUSY and 2T-physics gauge symmetries.
In a particular gauge the 4+2 theory reduces to ordinary supersymmetric field
theory in 3+1 dimensions without any Kaluza-Klein remnants, but with some
additional constraints in 3+1 dimensions of interesting phenomenological
relevance. This construction is another significant step in the development of
2T-physics as a structure that stands above 1T-physics.
