In the Halo 5 Guide it says to get the Flaming Ninja Emblem you need the Spartan Slayer Pack to unlock it and I have done that through the Spartan Slayer Commendation but still no emblem, not sure what to do. Any help would be appreciated.
You’re sure you completed it all the way through? You should’ve gotten a pack called “Spartan Slayer Pack” that contained the emblem you seek. Sadly, this is the limit of my assistance; that’s all I can tell you.
I hope you get your emblem soon!
