Dadofducks on youtube has posted a short video of his Walking Dead LE machine here.  The included video is a longer video with game play.  Having played the pro version during the Flippers release tournament, it is good to see the color in the inserts on the LE version.  The pro version seems to have mostly clear inserts with very bright white leds under them which gives the playfield a washed out look.  It looks like there is a diverter above the stand ups on the left of the playfield.   This diverter can divert the feed of a right ramp shot to load the cross bow.  The cross bow then swings out from its position against the apron and has a shooting while aiming side to side effect like a Steve Ritchie cannon.
