I made a technomancer and bought an Ares machine pistol with a smartlink already installed, but near as I can tell that's useless to me because a TM has no native way to establish DNI?
To use a smartgun you need a smartlink.
The smartlink take up capacity in an imaging device (such as a pair of goggles).
You can access the smartgun features if run a cable from your smartgun to your imaging device
You get reduced penalty from wind by one level, camera to shoot around cover without exposing yourself and increasing accuracy by two.
If you use wireless from your smartgun to your imaging device instead of a cable you also get a positive dice pool modifier of 1 dice.
The things you will miss out on because you don't have a data jack or trodes include 1 more positive dice pool modifier for wireless. And depending on your reading you must use a simple action to eject clip and change fire mode instead of a free [mental] action... and you can not fire the weapon without touching the trigger by using a mental command (but you can probably fire it with an ARO).
You don't use a persona for this (there is no need for a commlink... or a sim-module).
...Let's say my target has a cyberarm, a commlink, a smartgun, and I'm in VR.
...Would I see other devices, like his MP3-playing jeans?
Default setting you see the design of his Persona and his PAN
- and if his smartgun is not running silent then it will stick out as a dangerous Icon.
You can choose to see all his icons- that will be lots of icons.
(every single non-protected music album he got on his commlink will be a file icon of its own...)
...if I can search for a specific, hidden icon. Is that possible?
If I can only do a general search for hidden icons, my life is going to suck if every runner I come across has his devices hidden.
There are some debate on this topic and rules can be read either way
I choose to make this interpretation of the rules as they are written:
To spot an hidden icon you first have to have an idea that there is is one in the first place.
If his smartgun is running in silent mode then you would not see the smartgun by default.
You could run a matrix perception test to locate all hidden icons within the PAN, but that might or might not render you a list of quite a few icons...
If you have more information of the hidden icon your are looking for then you can ask a more precise question and get better results.
If you for example see your target in the meat world and see that he got an Ingram Smartgun with no cable attached to his smartgoggles but at the same time you don't see any smartgun icon from your augmented reality overlay... then you can take a matrix perception test to look for a wireless ingram smartgun icon on your target. Either you will find it or you will not find it (because you failed to locate it or because it is wireless OFF instead of running silent).
Is his cyberarm a device?
Yes, but cyberarms does not have a wireless bonus so odds are he have it wireless OFF and you will not see an icon for it in VR.
If you see your target in meat world you might see that he got a cybernetic arm but no corresponding device icon in AR.
You can try to locate the device icon, but if it is wireless OFF instead of running silent then you will never find one.
If yes, can I brick it? What happens?
If you attack it and don't manage to brick it in one data spike then your target will turn off wireless on his next action (or at the very least go full matrix defense). A cyberarm does not have any wireless bonus or function; it will function just fine with wireless OFF (odds are it will be wireless OFF to begin with). If you brick it then it will stop working until at least one point of matrix damage is repaired. The owner will probably not be too happy about it and he will probably come looking for you with his Ingram Smartgun (wireless OFF this time) in his left hand....
Is his gun a device?
It is.
If it have an internal smartgun then the smartgun system and the firearm is the same icon.
With enough Marks/Puppeteer can I make the gun fire? Can I engage the safety? Can I switch its firing mode? There's an example to eject the clip, but I'm not certain how much control I can exert.
Yes you can fire the gun.
Unclear on the safety.
Yes you can switch fire mode.
Yes you can eject clip.
(all three are DNI wireless action bonus or mentioned as a smartgun feature (p.433) so you will at least have access to them)
Can I do the above to any firearm
Unclear if you can fire the gun.
Unclear on the safety
Yes you can switch fire mode.
Yes you can eject clip.
(both are DNI wireless action bonus for firearm (p.424) so you will at least have access to them)
