Wow! Great job! You are a really excellent builder, and I can't wait to see the final product. The motorized action is ingenious! I wanted to tell you something, not rude but to inform you of something. On that kids MOC, Nazi Zombies is a minigame/game on one of the Call Of Duty games. Why they called it that, I don't know. I find it quite annoying when people say how "fun" it is. Meh, it's O.K., anyway just wanted to let you know. Oh, sorry for the long comment explaining that.
