Purge Troopers are the most challenging non-boss melee opponents in the game.  They come in three flavors which are designated by their weapons.  They are Electrostaff Purge Trooper, Electrobaton Purge Troopers and the Electrohammer Purge Troopers.  As for as the costume itself, I believe all three are identical.  The Purge Trooper design appears to be nothing more than a repaint of the TAC 30-07 Airborne Trooper.  The only thing that distinguishes the three types of Purge Troopers is the weapon they carry.  For that reason, I lumped them all into one entry.

If only one were to be released, the Electrostaff would make the most sense (and would be the easiest since the accessory already exists).  A hypothetical Purge Trooper figure would also lend itself to a natural “armory pack”  that would include all three weapons.
