We present results from a study of the eclipsing, colliding-wind binary V444Cyg that uses a combination of X-ray and optical spectropolarimetric methods todescribe the 3-D nature of the shock and wind structure within the system. Wehave created the most complete X-ray light curve of V444 Cyg to date using 40ksec of new data from Swift, and 200 ksec of new and archived XMM-Newtonobservations. In addition, we have characterized the intrinsic, polarimetricphase-dependent behavior of the strongest optical emission lines using dataobtained with the University of Wisconsin's Half-Wave Spectropolarimeter. Wehave detected evidence of the Coriolis distortion of the wind-wind collision inthe X-ray regime, which manifests itself through asymmetric behavior around theeclipses in the system's X-ray light curves. The large opening angle of theX-ray emitting region, as well as its location (i.e. the WN wind does notcollide with the O star, but rather its wind) are evidence of radiativebraking/inhibition occurring within the system. Additionally, the polarimetricresults show evidence of the cavity the wind-wind collision region carves outof the Wolf-Rayet star's wind.
