Description
There is an upgrade for the Address Disruptor called the Address Disruptor 2, which will replace the Address Disruptor in the player's inventory (making the 16 upgrades appear to only be 15). The Address Disruptor 2 comes with increased power and range, and fires red rectangles as opposed to the original Address Disruptor's blue.
The Address Disruptor 2 is found in the lower section of Kur, in a room just above Kur's bottom-most save room.
