On My Mark Achievement in Halo 5: Guardians
On My Mark
10Simultaneously assassinated two Elites in Blue Team co-op.
How to unlock On My Mark
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.
