In this note we investigate the generalised critical N=2 superstrings in
(1,2p) spacetime signature. We calculate the four-point functions for the
tachyon operators of these theories. In contrast to the usual N=2 superstring
in (2,2) spacetime, the four-point functions do not vanish. The exchanged
particles of the four-point function are included in the physical spectrum of
the corresponding theory and have vanishing fermion charge.Comment: 8 pages, CTP TAMU-57/92, EFI-92-3
