SRS99C-S2 AM Sniper Rifle — Stats & Guide

The SRS99C earns its S-Tier ranking through its 200 base damage and 5x headshot multiplier, which combine to deliver the single highest burst damage in the game. A headshot inflicts 1,000 damage, instantly killing any non-boss enemy regardless of shields or difficulty. Its night vision scope also provides unmatched situational awareness on darker missions, and the weapon can engage targets before they even enter aggro range, effectively turning many encounters into one-sided affairs.

Toggle night vision by pressing the scope button twice while zoomed in, which highlights all living targets in green against a darker background. This is most useful on Truth and Reconciliation, 343 Guilty Spark, and Keyes, where lighting conditions make regular scoping difficult. Night vision also reveals cloaked Elites that would otherwise be nearly invisible — sweep the scope across open areas slowly before advancing to catch them standing still. Be aware that night vision drains the scope's clarity at extreme range, so toggle it off when lining up shots at maximum distance.

Each mission typically provides 12-24 rounds of sniper ammo total, so treat every shot as a resource. Reserve sniper rounds exclusively for Elites, Hunters, and Jackal snipers — never waste them on Grunts or unshielded infantry. Aim for the head every time; a missed shot is two wasted rounds at minimum when you factor in the missed kill. On Two Betrayals and Assault on the Control Room, you can find additional sniper ammo tucked in high ledges and weapon caches, so explore each level thoroughly before moving on.

A single headshot to the driver of a Ghost or Shade turret is an instant kill, but damaging the vehicle itself takes many rounds and is not ammo-efficient. For Hunters, one shot to the exposed back or neck area kills them outright on any difficulty. If you cannot flank a Hunter, aim for the narrow gap in their helmet armor — this is a much harder shot but can be done from the front if you are patient.

Truth and Reconciliation is the sniper's showcase mission, with large open hangar bays, long sightlines, and multiple Jackal snipers to counter-snipe. Assault on the Control Room also features vast outdoor sections where you can clear entire Covenant patrols before they reach your position. Halo offers wide canyon engagements where the sniper dominates, and Two Betrayals gives you ample high ground to pick off enemies controlling vehicles below.
