How to unlock the Close Quarters Combat achievement in Halo: Combat Evolved Anniversary - Definitive Guide
After you rescue Keyes you will get to a room with two clocked Elites with Swords. Kill them, then there will be a short part where Keyes and Cortona talk strategy. Then a door will open and you will have to kill a few grunts. After you kill the grunts proceed through the door and turn right. there is a health pack and ammo for the sniper rifle, 24 shells. There are only about 5 enemies after this so you should be all set.
Just make sure you keep the sniper rifle through the whole level, no need to conserve ammo.
For this mission, there’s a positive and a negative. The positive is you start with 48 sniper rounds and there are ammo caches all over the first part of the level and a handful in the second part on the ship (look for the bloody marine corpses). The downside is you’re going to want most of those rounds for the Elites, you must keep the sniper rifle in your possession up to the end, and there is no pistol in this level to fall back on. That said, smart use of grenades, melee, and Optic Camo should get your through most of this level fairly painlessly.
Doing it co-op also simplifies this task as both players have Sniper Rifles. Sharing an equal load of the work will enable both players to conserve more ammo. Solo players can use a dummy controller to eke out the damage while the 1st player can hide as well.
Note: The Bandana skull means you'll have infinite ammo in your sniper, which guarantees you have at least 4 round at the end. If you already have the skull, consider using it.
