So what are you going to specialize in once you finish your High School? Are you going to join the Wetwork Group, the Pioneer Group, the Engineer Group, the Tracker Group, the Rogue Group, the Stalker Group, the Pathfiner group, or the Operator Group. For each group you join, you get exclusive armor, weapon skins, armor skins, visor colors, and emblems. At the end of each specialization, you gain an armor mod geared toward that specialization. Also, if you do not order the Limited Edition and decide to get the Standard Edition, you may have to wait on all the other specializations other than Wetwork and Pioneer. Here are the armor mods for each Group Wetwork - Stealth - Run more quietly, quicker assassinations, and only shows your outline when being scanned by Promethean vision Pioneer - Fast Tracking - When the armor mod is enabled in your loadout, you gain more EXP for each minute you have the loadout enabled. The downside is that you can use that slot for something that could help you in game Engineer - Drop Recon - Allows you to see ordnance drop locations before others Tracker - Requisition Armor Mod - Allows you to have three new choices for your PERSONAL Ordnance Drop Rogue - Stability - Do not get unzoomed when shot, but falters your accuracy slightly when being shot while scoped Stalker - Nemesis - Shows the user who last killed you on your HUD. Your enemies will know you are using this Armor Mod, and will likely plan accordingly by baiting you Pathfinder - Gunner - Allows you to move with turrets more quickly and slows down the overheat process for the turrets Operator - Wheelman - EMP blasts last shorter and your vehicle health recharges faster.
