Easter Egg

Red vs Blue: Episode 1 Easter Egg

On Episode 1, Chapter 5 of Spartan Ops, go over to the lava pit over the edge of the platform where all of the enemies were. On one of the rocks, you should be able to see a little box with a halo marking. Shoot it, and you'll hear a sound from the Red vs Blue intro.

Continue to play through the level, and you'll eventually hear Caboose of the Blue team talking about having to replace the radio guy because he had to take a bathroom break.

Red vs Blue Episode 2 Easter Egg

In Episode 2, Chapter 5, right at the beginning of the level, stick to the left part of the map until you go into a forest-type area. Keep sticking to the left paths until you see a glowing blob on the wall. Right below it, you should see a little box hidden in the bushes, shoot it.

Continue to play the level, and you'll hear Caboose, Church, Grif, and Simmons throughout the level.

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.

Red vs Blue Episode 4 Easter Egg

On Episode 4, Chapter 2 of Spartan Ops, at the spawn, use a DMR to look all the way at the other spire on the other end of the map. If you look to the right ridge, you'll see the small box. Shoot it, and the RvB intro music will sound.

Later on in the mission, you will hear a spartan named Vic talking about a party with Commander Palmer.

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.
