Halo 4 Cheats :
Easter Egg - Red vs Blue Episode 5 Easter Egg
On Episode 5, Chapter 5 of Spartan Ops, it is once again right at the spawn. All you have to do is turn around and use a precision weapon to scope out the box wedged into one of the rocks. Just like every other easter egg, shoot the box.
Later on in the mission, you'll hear the voices of Sarge and Grif of the Red team.
