Type-52 Special Applications Rifle

Description
This beam weapon, appearing for a brief moment in the Halo: Reach Multiplayer Trailer, appears to fire a purplish beam, much like that of a Sentinel Beam. However, the rifle style configuration and beam color of the weapon suggests it is not of Forerunner origin and stricly Covenant.

Trivia

 * The Unidentified Beam Weapon likely may replace the Sentinel Beam in Halo: Reach.
 * The weapon appears in the Multiplayer Trailer video for a very short amount of time (1:16-1:17 in the Trailer).
