Halo Wars Honor Guard Wraith Problem?

[Josh]

I bought the limited edition for xbox and downloaded the wraith but the skull isn't there with other skulls

What do you mean by skull? Go to options and it should say to turn on or off the flaming warthog and honer guard wraith. I dont think they work on campaign but it should work online or in skirmish. Make sure you put in the right codes. Good luck
