Only the Tower trap can be upgraded once upgraded the trap will fire rockets instead of sniper rounds. There is also a Tower Trap, which assists the player by shooting zombies with sniper rounds. A new utility is also introduced, the Gondola, which transports players between the main prison and another part of the island, similarly to the Zipline in Shi No Numa/ Call of the Dead. The map features three new traps, the Fan Trap, the Acid Trap and the Tower Trap. Purchasable traps also return, last appearing in Ascension. In addition, holding down the throw button for a few seconds will allow the player to throw the tomahawk a further distance. These tomahawks can be thrown at power-ups and retrieve them for the player. It takes about three seconds to recharge before it can be thrown again. The weapon can pierce through multiple zombies and will return back to the player. There is also a unique tomahawk-like weapon called Hell's Retriever, with a red aura. There is a new Wonder Weapon featured, the Blundergat, a cross between a Blunderbuss and a Gatling Gun. Also returning from Nuketown Zombies is the Fire Sale power up. The LSAT is also featured, having only appeared in the zombie variant of Nuketown. The Death Machine is now a standard box weapon, and no longer a powerup. The Uzi and the AK-47 make their debut in Zombies, as well as the M1927. The map features several additions to the players' arsenal.

This map also introduces Guard and Prisoner Zombies on the island.

Zombies on the island have red eyes, and the mystery box has a different look with a red glow. The four playable characters are Michael Madsen as Finn O'Leary, Joe Pantoliano as Albert Arlington, Chazz Palminteri as Salvatore DeLuca, and Ray Liotta as Billy Handsome, all of whom are Gangsters who have been locked up on Alcatraz and were planning an escape on the night of the outbreak. Mob of the Dead is located on Alcatraz Island during the Prohibition-Era of American history and is the biggest map in Zombies history to date.
