So I was wondering if anyone is willing to help me out with achievements for halo 4 btw I heard there someway to unlock 343 armor in halo 4 does anyone know how I can unlock it. Thanks for the help.
You unlock the secret ‘Raider’ armor by putting in forerunner symbols in the classified section on waypoint.
Shoulders + Torso + some concept art and exp (http://www.youtube.com/watch?v=HjFfyCGpQLY)
Helmet (https://www.youtube.com/watch?v=JExDHcq4-kQ&list=UUxu2rRKzUAv0eqNhORBGkPg&index=2&feature=plcp)
To get to the classified section on waypoint on your computer, go to
(http://www.halowaypoint.com/en-us/classified)
there is also a classified section on console that is pretty easy to find
I’m not really interested in helping with the achievements, but good luck!
(p.s. all of the armor comes with a bit of extra xp
Thanks fellow spartan glad there someone could help out another spartan
