It is of one of the assault robots that is manufactured by Northern Gun in the RIFTS setting. The line art version was released as sneak peak in the Rifter #62 and will be featured in the upcoming, highly anticipated, long awaited “RIFTS: Northern Gun book 1, both written by Matthew Clemens and Kevin Siembieda and published by Palladiumbooks.
The Gunbot is an aggressive combat machine, a weapons platform loaded down with more guns than armor. It is a “robot-hunter” like the tank-hunters of old, a bipedal cannon made for ambushing more heavily protected opponents. It has exceptional maneuverability for engaging threats. Those that are unfortunate enough to step into the Gunbot’s sights will come under fire from its ion cannon/rail gun primary weapon. Dual Mini-missile launchers and a heavy 3 burst maximum variable grenade launcher completes the package, giving the Gunbot a range of different weapons options with varying effects and engagement distances.
Model Type: NG-V47.
Class: Infantry Assault Robot.
