If you missed my previous post of the LEGO May 2016 Store Calendar, the exclusive minifigure was revealed to be the LEGO Star Wars: The Force Awakens First Order Stormtrooper (30602). At first, the minifigure looks extremely close to the one found in the First Order Battle Pack (75132). The only difference is that the torso has a minor addition and a backpack. This version of the Stormtrooper looks to be Jakku version of the character but that could be debated.
Initial responses to the First Order Stormtrooper (30602) have been somewhat negative as many people are fine with the one that came in the Battle Pack. Since technically it is a new exclusive, albeit the small changes, polybag collectors will still probably want one however there could have been other better choices of characters. Do note that the threshold to get the minifigure for free is now $50 for 2016 instead of the $75 from previous years. Maybe LEGO is banking on people getting multiples of this polybag with the lower price.
