I got the code in an email and redeemed it on xbox.com. When and how do we use these because I cant select them or find them?
Select Spartans receive priority access to a number of Specialization kits in order to improve combat performance in various fields. The following kits will be available with Specialization Priority Alpha :
Engineer - The Engineer allows you to predict when and where ordinance drops are made, essentially providing you with an ordinance radar. Beat your enemies to the punch and scope out all the ordinances before they do.
Tracker - The Tracker’s armor mod allows you to get the most out of ordinances, by recalling your current ordinance to request a new one.
Rogue - The so-called Rogue increases your stability while aiming, and prevents you from losing your aim while being shot at in zoom mode.
Stalker - The Nemesis armor mod provided to the Stalker allows you to effectively track the last person who killed you throughout the entire map. They’ll regret messing with you.
Pathfinder - The Pathfinder is geared towards getting the most out of mounted weapons. With the Gunner Armor mod, all mounted weapons will cool down faster when overheated. Your movement speed is also increased while carrying a detached turret weapon.
Pioneer - This Specialization allows you to gain an edge over your opponents by gaining more experiential data from each encounter, effectively earning ranks faster than anyone else.
