The Tower Trap is a utility featured in the Zombies map Mob of the Dead. It is located on the docks, near Juggernog and the M1927. It activates a sniper turret on the tower which fires semi-automatic rounds at any zombies in its range. It costs 1000 points.
When it is activated, a door opens for a short while to reveal a Voltmeter, this can be activated in the Afterlife to upgrade the tower to shoot rockets instead.
