Hello Halo Support,
I was playing Halo 4 Spartan Ops on the Xbox 360, and notice on Episode 5 Chapter 1 “Spartan Miller”, a graphical skybox glitch occurs, when the initial Promethean Watchers slip-space teleport in, portal 2 and 3 specifically. When you look up at the portal, the game has a chance of creating a large pink square removing the skybox temporarily… yet… I noticed this glitch is not consistent and on some play throughs doesn’t happen at all.
Should be a one time thing. Il be surprised if it ever happened again.
