I was thinking, and it came across my mind about the idea of having a type of robot companion that could per say stay attached to your back, or something like that, and whenever you wanted, you could activated this robot companion and have it help you. It would be like a spider robot, and when you activated it, it would crawl of your back and attack enemies. This would suit stealth players who find companions annoying when at stealth, for they sometimes get in the way or attract enemies. I know this would be very hard to do, but I believe it would be a great mod for the new vegas nexus community.
