I just input a code for "Oni 1" and way point froze violently.
It unlocked an emblem? Okay thanks 343 forums.
Here's the codes go into waypoint > classified > raider set > press X then input the these codes. All you gotta do is make sure you beat chapter 1 and 2 for these to work, it's not possible to unlock 3 yet until 343 releases another of their cryptic messages that their forum destroys in 10 minutes.
Think I figured it out. Right now we're only on Episode One of Spartan Ops. All these achievements describe episode 2 3 4 5 etc. That achievement in particular is Chapter 1, Episode 5. Hence why it doesn't unlock
Does raise a good point of how the hell the chip she is on is compatible. It previous games it was some sort of wireless transfer and looked way better. I hate every time you interact with an object and the view gets locked into Chief doing the action. It is so fucking Call of Duty.
i only played through the first level of the campaign and a couple mp matches, mp is good and it's halo so you know it'll have legs, for the campaign it's just good to see the chief back and not nameless spartan 6 and odst guy
