...well, he does! Watch the trailer, when he's sucking in Mudflap, check out his right arm. There's a little two gun turret that tracks Mudflap as he enters his mouth. At first I thought it was smokestacks or something, but no, it is a little gun turret! Well, I guess it's so people don't climb on him when he's in grinder mode? Let me see if I can find a screen capture. Has TFW done screen caps for the third trailer yet? Well, if you watch the trailer you can see it quite clearly, regardless.
