Give AI shells a magtractor

[Kubius]

I've played as a ghost drone a few times recently, and quite liked using the magtractor - it should be a thing for AI shells as well. It'd majorly boost their versatility and ability to aid the crew while not being as strong as a proper remote-control borg frame.

Making it restricted to low-power could be a good modification for the shell version to avoid it getting out of hand, but on the other hand, high-power would be balanced out by the AI shell's wimpy power capacity and would help get past the fact AI shells can't pull anything (which is probably something that should stay, considering their tiny size). This particular choice is up to the implementer.
