Compared with other examples of the Covenant's armory, the Carbine is somewhat unusual: its high speed radioactive ammo is powerful, but its single-shot design and clip feeding instead of batteries seem strangely old-fashioned. Don't misjudge its strength. When used by a professional, the Carbine is an accurate weapon reminiscent of a cross between the Sniper and Battle Rifles.
With a 2x zoom facility, it's possible to make lethal headshots from afar. The Carbine's only real shortcoming is that your position is betrayed by a green trail with each shot. When you get your hands on one, be sure to take advantage of it.
This weapon is superior to the human battle rifle if one is able to get headshots, due to its greater rate of fire and larger magazine capacity. Also for close range the Carbine is much better than the Battle Rifle. However, the battle rifle requires less aiming, and is much more commonly available. Keep in mind though the Battle Rifle out shines the Carbine on single player as the three shot burst enables easier head shots, and in some cases multiple headshots on numerous unshielded opponents. Case in point, up to three grunts can be killed in one burst quite easily for a skilled combatant. Carbine ammo is also generally in short supply.
The Carbine is hidden in most levels it is in: e. g. in Ivory Tower it is placed behind some stacked crates and in Waterworks, it is to the right of either base on path on the wall to the teleporter exit.
