Due to this highly variable damage profile, it is hard to 'guess' how lethal the MTS-255 is at certain distances. And just like all other shotguns in the Call of Duty series, the MTS-255 eventually ceases to deal any damage whatsoever. However, damage rapidly declines, and eventually, the MTS-255 will only deal 13 damage, resulting in an eight pellet kill. In close quarters, the MTS-255 will deal 63 damage per pellet, scoring a two pellet kill.
The MTS-255 is a highly variable damage per pellet shotgun. The MTS-255 is the second most expensive shotgun in multiplayer, costing eight Squad Points. Hesh also uses it in ' Clockwork' in his disguise. The weapon is also used sometimes by the Federation several MTS-255s can be seen as well scattered throughout Federation areas.
During the mission ' No Man's Land', lieutenant David 'Hesh' Walker finds an MTS-255 in his abandoned house, commenting 'Never thought I'd see this again', which implies that he had used the shotgun once, or that his family owned it.
