Dont know them all but here is some:
Spartan IV: SR
Engineer: EN
Operator: OP
Stalker: ST?
Rogue: RG
Tracker: ?
Wetworks: WT?
Cant remember the rest of the specializations.
Wetwork is one of the specializations in Halo 4. Only 2 specializations are available at launch, Wetwork an Operator. When you reach rank 50 in Halo 4 you can choose a specialization.
Reach level 50
Halo 4 offers 8 specializations. They include Wetwork, Pioneer, Engineer, Tracker, Rogue, Stalker, Pathfinder, and Operator. Each offers 10 new levels to the player.
Once you reach level 50, you can then choose a specialization
No. If you played Halo 4 within the first 2 weeks of release or pre-ordered, you could use a code (either sent to you by Microsoft via Xbox Live or from your Halo 4 limited edition package) to get all specializations. These specializations will eventually be released to all players, but everyone only gets 2 (unless you have a code) to start with. But to unlock any of them, you have to be level 50. Ex: I enter my code, I get to Lv. 50, I can use 1 of any of the specializations. Ex: I didn't enter my code, I get to Lv. 50, I can use 1 of 2 specializations, but more will be released later in the year.
The "DewXP" Mountain Dew double XP codes for Halo 4 can be found on the inside of the lid.
if you go on youtube they will tell you the codes but you have to have halo waypoint to make them work if you don't worry about it the waypoint is free.
there is no codes in halo 3 ... -.-
Complete Specialization Spartan IV at SR50 then go on the spartan hub, select Specializations and then choose Stalker. If you choose something else don't worry as it only takes 10 SRs to complete all the specializations after Spartan IV.
the beta's been over for 4 months dude
nowhere because there are no cheat codes for halo 3
SORRY BUT HALO IS A FAIR GAME THE ONLY ADVANTAGE YOU GET IS EXPERIENCE AND ADVANCED MOVES I KNOW THEM LOOK 4 ME (XxGWOPBOYZxX)
