From Halo Bulletin 8-15-12:
Tracker Specialization: Spartan optimization for long-range target tracking (trans-continent and off-world), particularly in scenarios where conventional tracking has failed or such a substantial time has passed that the trail has gone cold.
Requisition Armor Mod: The Requisition armor mod allows users the ability to recall their own ordnance requests in order to acquire more helpful weapons in the field.
The Requisition armor mod – the helmet of which has a scanning device on the front of the visor – allows you to choose a new set of personal ordnance when personal ordnance is granted. When the menu for a personal ordnance appears on your screen, hitting left, down, or right on the D-pad selects the relevant option. When you have Requisition and hit “up”, you receive a new random selection of choices. This armor mod doesn’t have knowledge of what ordnance had previously, so while you’re not guaranteed better choices, you’re more likely to get the weapon you’re good with or your favorite power-up, if you didn’t get it the first time around.
Objective: This mod gives you a “Do-over.” Don’t like your ordnance drop coming in, use this to change it.
Subjective: Considering what has been promised as a fast paced game, I’m not yet convinced this is a good mod. I definitely see it’s usefulness, especially in slower paced games where tactics are involved, instead of straight slaying though.
Armor: This armor is very good. Ah, but yes, that helmet. Take out those three white dots and make that whole area the visor, and it would look better. More “Recon” in style. Still it’s one of the better ones, IMO.
Emblems: Okay, these I really dig. (Yeah, that’s a ’70s term you young’ins…) From the ringed planet with satellites to the “Daily Planet” emblem at the bottom, I like them all.
