One thing I think could use some clarifiers is how we apply limitations for close-range mind control.

Standard innate attacks do not have a requirement to be able to see a target: you can fire blindly. So applying -30% melee C to it is reducing you from "ranged blind" to "close blind".

Mind Control however requires seeing or touching: you can't fire blindly. So should Melee C still be worth -30% ? You're only losing the ability to attack people you can see, unlike Innate Attack you're not losing the ability to make attacks against invisible foes.

Since you're losing less, it doesn't seem like it ought to be worth the full -30%.

If I had a melee-based ability (let's say possession) adding Ranged+40% w/ Sight-Based -20% would work out to +20%

So if we're removing that aspect, maybe it should just be -20% instead of -30% ?

This still might be worth debating since the requirement of getting Cybernetic Only to work on those with Digital Mind seems to imply it is telepathic, unless Digital Mind only makes you immune to MC (telepathy -10%) [40] and not MC [50]

B150 doesn't really talk about stuff like language, and B151 mentions:

If you are nonsentient (IQ 0), you have no interest in doing anything but following your programming!

This raises a question of how your master 'programs' you if you can't understand language though... B15 requires that you be sapient (IQ6+) to have language, at best you can have gesture/vocalization and simple commands per B458, but I think even that requires at least IQ 1, so I'm still confused how IQ 0 would work.

How would you even interpret program (even super-literally) at IQ 0? The only thing with IQ 0 that I've seen which can take actions without an external controlling mind is that man-eating plant in GURPS Fantasy.

Linguistic Programming's "a master language understood by all sapient minds" isn't Cosmic-enhanced which seems to imply that faculties of the target don't matter. The sound/hearing is even involved in that case is due to having the Hearing-Based limitation...

LP's implied "I can't use my power if gagged" isn't exactly how I understand Sound-Based to work though...

If however I had Sound-Based on something like Innate Attack (Malediction) the standard IA rules require me to pick a place where my attack comes from: so if I were screaming, "Breath" would make sense, whereas if I'm firing a sound cannon from my hand, it'd be Beam/Bolt.

Mind Control doesn't talk about that but it's probably be a good idea. I'm pretty sure you'd need to if you took "Weaponized" but even for non-Weaponized Mind Control it is appealing.

Like for example if you specify "breath" then you can't MC with your mouth covered, if you specify "gaze" you can't MC with your eyes bound, if you specify jet/bolt then you can't MC with your hands bound.

That might be overly limiting, so if that's not built in then Linguistic Programming deserves additional discounts, since it seems like you can't use it when you're a mute (can't talk) or have your mouth occupied (biting, chewing) which AFAIK aren't standard Mind Control limitations.

PP63's suggestion doesn't for example actually require that you have anything like Telesend accompanying it. P72's Beast Control is same.

They may well seek immediate revenge.

Also worth noting that taking active defenses forces a Will-3 check to keep concentrating, regardless of whether your next maneuver is a concentrate or not.

This wasn't in basic set, but the rules for treating Mind Control as if it were spellcasting (this also applies to anything with "Requires Concentration" limit) is from GURPS Powers

Sense-Based is one I think is worth dwelling upon, since there is an inherent requirement of EITHER touch or vision to use it, which is akin to Either/Or limitations of Sense-Based, Reversed.

I've seen both Hearing-Based and Sight-Based given -20%, even though I wonder about that.

Hearing-Based AFAIK doesn't explicitly remove the EITHER requirement, so you need to touch+beHeard or see+beHeard.

Super-Hypnotism (also P149) uses Vision-Based (your target must be able to see you) but "eye contact, a touch isn't enough" raises some questions.

This seems to imply eye-to-eye (you must see target, target must see you) so one of the inherent options of Mind Control (touching target instead of seeing them) seems to be removed without giving a reward for that.

Unless of course it requires specifying one of these from the outset, but I get the impression all chars with wild MC can choose either option.

Just the chance that someone may be able to Mind Control you means that you can no longer trust your experience, memories or even that you are, in any meaningful way, still you, while that person exists.

DC had some good examples of this, like Batman's distrust of Zatanna in Identity Crisis, or Superboy's distrust of Miss Martian in Young Justice.

One thing worth pointing out about Reprogrammable, since it's tied to Mind Control explicitly, is the vulnerabilities that might exist for it.

M152 for example has it in the Undead templates who also have the Automaton trait.

B250 mentions that Mind Control doesn't work on those with the Automaton trait, because if you have EITHER an IQ of 0 or "no free will" (Automaton) you're not a valid target.

B263 defines that as Low Empathy / No Sense of Humor / Slave Mentality so I guess you need a combination of all 3 traits to be immune to Mind Control? Or is there some zero-point feature not mentioned in the meta-trait which bestows the immunity? "No free will" sounds most like Slave Mentality if I had to choose a single trait out of the three, but I don't know that SM would make you immune to Mind Control spells, if anything I would assume you'd be even MORE vulnerable.

Really only IQ 0 being immune makes sense since there "no mind to control". Having merely "no free will" doesn't really make sense for being immune to MC: that just sounds like you'd be very easy to mind-control, but it might be a waste of FP since you could probably just use Influence Skills for free to get the job done.

The undead templates do not have IQ 0 (skel/zombie are IQ 8) so what I figure is, the purpose of Reprogrammable is so that they can be given orders by their designated master, because they all enjoy the "Indomitable" advantage making them immune to social influence skills.

It seems like if you want to make undead immune to mind control magic, they ought to pay for it like the Demon does (M155) and not get it as a free benefit baked into the Automaton meta-trait. If that's a 30pt benefit then we should add some kind of -30 disadvantage to counterbalance if the price is to be kept at -85 instead of -55

Even making it a cost of IQ 0 things seems good: if you don't want it to cost points then someting akin to "Insensate" or "Nonautonomous" (toolkit 2 races pg 12) could be made -30 instead to balance it out?

Personally I think you gain so many points from buying IQ down that being forced to pay some points for immunity to mind control (even when you have no mind to control) wouldn't be the worst thing, and it would help in keeping 'equipment as allies' competitively priced.
