M45D Tactical Shotgun

The M45D Tactical Shotgun is the UNSC shotgun that is featured in Halo 4 and Halo: Spartan Assault.

Design details
The M45D is a model of UNSC shotgun first seen in Halo 4 and was the standard-issue shotgun to UNSC forces stationed aboard the UNSC Infinity during the Battles of Requiem. It's appearance in Halo: Spartan Assault suggests that it may have first entered service (or at least entered mainstream use) during the immediate aftermath of the Human-Covenant War. It appears to have a higher rate of fire than its' previous variants, along with greater damage, but the range seems to have been decreased. The design is consistent with 343 Industries' mandate that all Halo 4 weapons have a sci-fi look about them. The M45D utilizes a 6 round magazine, much like the M45 Tactical Shotgun from Halo: Reach. It is likely a newer model of shotgun that is currently phasing out the M90. It is the primary weapon of the survivors in Halo 4's "Flood" mode and is also a possible ordnance drop from the in Halo 4's War Games.

Trivia

 * The M45D represents the greatest distinction in its appearance from previous models of UNSC shotgun.
 * It appears to have a higher rate of fire than previous variants of the shotgun.
 * The shotgun sounds far more realistic than previous iterations, using recorded audio from actual firearms. When it is being pumped after firing, one can hear an echo of the shot reverberate back to the player.
