You're No Chips Achievement in Halo: The Master Chief Collection

This Easter Egg can be found in the mission, Composer.

About halfway through the aforementioned mission, the Master Chief will be required to clear out a room filled with scientists that are under attack by a pair of Covenant Hunters. After this fight, head through the "objective" door that leads to the main elevator within Ivanoff Station. Inside, there will be a lengthy cutscene where Master Chief and Dr. Tillson descend into the facility where the Composer is being held.

Once you regain control of the Master Chief after the cutscene, head through the winding corridor on your right and you will then exit into the Composer's large chamber. Ignore the objective at hand and travel to the far side of the chamber where you can see an observation room with the words "IVANOFF STATION" written on the paneling. On the platform outside this observation room, there will be a group of two Marines testing out one of the new Mantis mech. Stay close to the Marines here and after they finish their witty exchange of dialogue, the achievement will unlock a few seconds later.
