I haven't played it personally, but these new troopers look like a cross between the Royal Guards and a Stormtrooper.
Looks like a modified TK Chest, TB Boots and Knee armor, Modified Darth Revan/Royal Guard Helmet.
Anyone know more about them? I haven't seen any discussion about them on the forcepike forums.
