Hell's Retriever

The Hell's Retriever is a new Power Up in Mob of the Dead. The player gets the Hell's Retriever by feeding 15 zombies to all the Hellhounds.

When it is thrown, it can go through multiple Zombies at once, and after traveling a certain distance, it boomerangs back to the player who threw it. It can also be charged up for more damage by holding down the tactical button, for a maximum of two pulses. The easiest way to see the pulses is to look on the grout at the players feet while charging the hells retriver, however this is not recomened as you will not be able to see the zombies coming at you that you are trying to kill (assuming that is the case). If the player throws it towards a Power-Up, it will grab the powerup and bring it back to the player. It's also on fire, hence the name.

Players' will never lose the Hell's Retriever unless they die. Throwing it does not get rid of it, as players simply have to wait for the weapon to "cooldown" before using it again. the cooldown seems to be under 10 seconds, give or take.
