How to unlock the On My Mark achievement in Halo 5: Guardians - Definitive Guide

Mission: Blue Team
Difficulty: Easy (Co-op)

As you enter the first room with enemies near the beginning of the level, sneak to the left, assassinate the grunt, and jump up to the vent with your partner. Inside the vent, one person takes the right turn, and one person continues straight. Each person can drop down the vents and onto an Elite. Once in position in the vents, together, countdown so you both assassinate your Elites at the same time. To assassinate an Elite, you must stealthily hit them from behind and hold the melee button. If both players assassinate their Elites at the same time the achievement will unlock. If not, reload last checkpoint and try again.

I gave you a positive because(even though I've done this before) this is the only video where the person is smart enough to show the killing from both angles. Awesome!

This achievement must be done in Co-Op Campaign and thus requires an online connection.

After entering the medium-sized lab towards the beginning of the mission, hitch a left up a small ramp and assassinate the Grunt who’s working on a terminal of some sort. Now look directly above you to spot the open ventilation shaft. Both players will want to hop up and crawl inside the vent. A few paces in, one player will need to turn right into the adjacent duct and position themselves above the open hatch. There is an Elite right below! The second player should continue down the main shaft, where there is another open hatch overlooking an Elite.

Once both players are ready to drop down for the attack, communicate a countdown and then drop behind the Elite and assassinate your respective targets at the same time by holding the melee button. If timed correctly, the achievement will unlock right away. If it doesn’t, revert to your last checkpoint and try it again.

To complete this achievement solo, you simply need two consoles with a gamepad for each console. As in the video, you aim each gamepad at the Elitnik and, at your own count of 3, jump on them, pressing only 1 button on each of the gamepads.
