CareTakers

So First off I would like to say that I think caretakers are a great idea and a very cool concept.
Secondly id like to present an idea on how the fight mechanics could go with them.
I was thinking what if it had the two modes hunter and turtle as shown in the community update, but instead of only explosive damage it would take bullet and melee damage as well while in hunter mode and would regress to the turtle form for a certain period where it could then be deactivated by either a lengthy hand process with some kind of tool or with explosives. meanwhile while possible having some kind of weaker defense system like a turret or smaller robots.
