"Quickly finding popularity across the Wilderzone, the Twinfusor series fires two disks per reload. This heavy version has been modified for Juggernauts." In-Game Description.
The Heavy Twinfusor works like any Spinfusor in that it fires explosive disks in a straight line over long distances. The major difference is that the Heavy Twinfusor can fire two disks in quick succession. Each Twinfusor disk deals less damage than a Spinfusor MK-X (616 vs. 924) however if both disks hit their target the combined damage is greater (1232). After two disks have been fired the Heavy Twinfusor reloads with a 2 disk clip. The higher total damage makes this weapon ideal for players who are sure of their accuracy.
