Robots for grenading your opponents

Hey everybody! You all love robots that can blow the crap out of stuff right? Well enter the grenade bot which can fire a whole heap of grenades at a ridiculously high speed to ensure that your opponents are dead long before you have to rouse yourself off the couch. Plus they mention a million rounds/minute gun. Now thats just plain insane, I mean what the hell could you kill with a million rounds a minute thats just plain stupid.
