The Mz-99 is a popular weapon among private bodyguards and armies, security people and members of criminal organizations. Its design may seem simple, but is in fact quite unique. The bullets are shaped into long, energized needles, that get extra spin from the Promptitude Sputter bay. The weapon looks scary in action, due to the high firing rate, but in fact each bullet does low damage. The 'Wild Canary' is a modification of the 'Rubi-Ka' version, where the nano pylons have been exchanged with Hyper Pylons, and an Opto-Bot scope has been added.
