  The CHandra Extended Emission Line Region Survey (CHEERS) is an X-ray study
of nearby active galactic nuclei (AGN) designed to take full advantage of
Chandra's unique angular resolution by spatially resolving feedback signatures
and effects. In the second paper of a series on CHEERS target NGC 3393, we
examine deep high-resolution Chandra images and compare them with Hubble narrow
line images of [O III], [S II] and H$\alpha$, as well as previously-unpublished
mid-ultraviolet (MUV) images. The X-rays provide unprecedented evidence that
the S-shaped arms which envelope the nuclear radio outflows extend only
$\lesssim$0.2'' ($\lesssim50 pc$) across. The high-resolution multiwavelength
data suggest that the ENLR is a complex multi-phase structure in the
circumnuclear ISM. Its ionization structure is highly stratified with respect
to outflow-driven bubbles in the bicone and varies dramatically on scales of
~10 pc. Multiple findings show likely contributions from shocks to the feedback
in regions where radio outflows from the AGN most directly influence the ISM.
These findings include H$\alpha$ evidence for gas compression and extended MUV
emission, and are in agreement with existing STIS kinematics. Extended
filamentary structure in the X-rays and optical suggests the presence of an
undetected plasma component, whose existence could be tested with deeper radio
observations.
