The M960 appears in all of the Remember When... storyline maps. It has a fast firing rate, low recoil and penetration power. It is one out of eight submachine guns in the storyline. It has good damage and it is one of the most powerful submachine guns. This weapon has one of the largest ammo conserves of any weapon, rivalling even light machine guns, with 500 rounds in reserve and 50 rounds in the weapon when it is obtained. It can only be obtained via the Mystery Box.
The M960 is a great weapon to have in almost any situation. It has a one-hit kill ability up until Round 6. Its fast rate of fire and low recoil makes it a great weapon when it comes to cutting down a swarm of zombies. However, this fast firing rate will feed through the ammo quickly and ultimately leave the player defenseless. Because of this, it is recommended to fire in bursts to decrease the loss of ammunition. Its low penetration power makes this weapon extremely ineffective when shooting through obstacles. This weapon should be pack-a-punched by Round 15.
When Pap'ed, the M960 becomes the Dino Slayer. After it is upgraded, its damage increases to 375-450 and its magazine size increases from 50 to 75 and its reserve ammo increases to 750. This weapon also gains a ACOG sight and increased stability. It should be traded for a better weapon by Round 27.
