The recently completed VIMOS Ultra-Deep Survey (VUDS) is an enormous 
spectroscopic survey aimed at the high-redshift (z>2) universe targeting 
roughly 10,000 very faint objects (i'<25) across three well-known fields 
of the sky. Though originally designed as a "field" survey, VUDS 
observations, in tandem with additional existing spectroscopy, deep 
multi-band optical/NIR imaging, and other multi-wavelength ancillary data, 
were used to perform a preliminary exploration into the effects of environment 
in the early universe. I will discuss the initial challenges and triumphs of 
this investigation including the discovery of two massive proto-clusters of 
galaxies at z~2.9 and z~3.3. I will then discuss ongoing work attempting to 
characterize the remaining ~40 spectroscopic overdensities found to date 
in VUDS, discuss peculiar single structures recently detected, and future 
prospects for defining what an overdensity is and how membership is 
determined in order to properly attempt a complete census within VUDS of 
both the properties of the member galaxies and the structure of these 
forming structures.
