Give Him the Stick Achievement in Halo: The Master Chief Collection

Towards the beginning of this mission, you will come across a Marine who is trampled by some Jackals. This Marine drops a Sticky Detonator to make sure to pick up since you’ll need it during another firefight.

After making your way through Ivanoff Station, you will eventually pass through a corridor where a scientist explains the situation ahead in the laboratory: a pair of Hunters are attacking the remaining scientists. At this point, you’ll want to enter the lab and face off against the Hunters by only utilizing the Sticky Detonator.

Keep in mind that the Sticky Detonator only has five shots, however if you are playing on a lower difficulty setting, the Hunters can be killed with one or two shots each so you’ll have plenty of ammo. In addition, the small cubicle-like room in the back right corner of the lab has extra ammunition if necessary. After both Hunters here have been killed with the Sticky Detonator’s rounds, the achievement will unlock.
