Great sub, really having good fun with it but there's a major issue I've run into eventually every time using it where the doors to all the Totems are open but for some reason one of them acts like it's closed. This is a small issue in that that Totem is now entirely useless but a major issue when playing with AI in that they'll try to fix any issues in that Totem while the entire sub is falling apart around them! :) On a side note I also can't do the "battery" command, but don't see the need to! :D
