Close Quarters Combat Achievement in Halo: The Master Chief Collection

At the start of this mission, you are automatically equipped with a Sniper Rifle that holds about forty-eight rounds. Fortunately, the first half of the mission takes place outdoors and this is the only time the Sniper Rifle will be useful. Once you’re inside the Truth and Reconciliation, the Sniper is rendered useless which means forty-eight rounds should be just enough for the outdoor portion of the mission.

Overall, when using the Sniper Rifle, be sure to pick your shots wisely. Headshots will be key in killing Grunts, Jackals and Elites from afar. When engaged in close-quarter combat, utilize grenades, melee attacks and any other secondary weapon so that Sniper Rifle ammo is not mindlessly used.

Playing this mission cooperatively may also be a good strategy for this achievement, as it cuts the workload of one player having to use their Sniper Rifle during the first half of the mission. So long as there are at least four rounds left in the aforementioned weapon before climbing aboard the Covenant dropship with Captain Keyes, the achievement will unlock.

Note: Activating the Bandana skull for this mission results in obtaining infinite ammo for any weapon you pick up or have equipped. With that said, you can activate this skull in the Campaign lobby and just carry the Sniper Rifle all the way through the mission for this achievement.
