Type-31 Needle Rifle

The Type-31 Rifle, also known as the Needle Rifle, is a Covenant infantry weapon that was used during the Battle of Reach.

Design Details
The Type-31 Rifle fires unconventional long and sharp projectiles similar to the Needler. The projectiles detonate several seconds after coming to rest in soft tissue.

Not all that much is known about this weapon, other than it is a medium-range, headshot-capable, two-hand rifle. Unlike the Needler, however, the needles do not "home", or track on the enemy, they fire in a straight line, similar to the M392 Designated Marksman Rifle. It seems very similar in appearance and functionality to the Covenant Carbine along with the barrel of a Beam Rifle.

Trivia

 * Unlike the Needler, the Needle Rifle is unable to supercombine. Bungie has stated this is due to balance issues.
