Nakata'vho-pattern plasma repeater

The Type-51 Directed Energy Rifle/Improved (T51 DER/I), more commonly known as the Plasma Repeater, is a plasma-based Directed Energy Weapon used by the Covenant Empire, specifically the Sangheili, during the Battle of Reach in August 2552.

Description
The weapon's rate of fire will slow as it is fired and the weapon heats up. This can be solved by manually venting the rifle with the reload button, which can be done all at once or gradually. However, as the weapon overheats and the rate of fire slows, the accuracy of the weapon will increase.

It is very likely that the Type-51 DER is either new to the Covenant arsenal or it is a branch specific weapon, as it has only been encountered by the UNSC very recently and only in very limited numbers.

Trivia

 * According to Bungie, the Plasma Repeater is the Covenant's equivalent to the UNSC's MA5 Series.
 * The weapon's front end has a striking aesthetic similarity to the Type-25 Directed Energy Rifle.
 * The weapon's targeting reticle is also similar to the Plasma Rifle.
 * The weapon was designed primarily for Multiplayer for balancing purposes, and it will most likely not appear in Campaign.
 * The weapon's front end bares a resemblence to the jaw structure of an Elite (the "teeth" at the front of the weapon in particular).
 * If you hold RB(or any other reload button) the weapon will open to cool itself down.
