Halo 4 Cheats :
Easter Egg - Red vs Blue Episode 3 Easter Egg
On Episode 3, Chapter 4 of Spartan Ops, right at the spawn, look up at the tops of the trees, and you will see the same little box from the previous easter eggs. Shoot it!
Later on in the chapter, you'll hear Grif and Simmons talking while the ships are dropping the Mantises.
