Commlink Programs:Command - You'll be spending as much time in Captain's Chair (AR) mode as you will Jumped-In (VR) mode. Command replaces your mental attributes for many tests in AR mode. Get it as high as possible.
Tactical Network Software - Get it. For both your personal commlink and to run in all your drones and vehicles. TacSofts mean a dice pool bonus to a ton of tests. You as a rigger will have enough 'friends' to always be running a Tactical Network.
Biofeedback Filter - helps if you get damaged while jumped in.
Vehicle Attributes:Pilot - Anytime a drone is in Autonomous Mode, this is it's brain. It also sets the System Rating for the vehicle and is thus the limiter on what rating software you can run in the vehicle.
Response, Signal -
Response replaces your meat attributes on many tests while in VR mode.
Signal determines how far away you can control your drones from. Upgrade both of these attributes the same way you would on any other device. Note that you can only upgrade these attributes by a maximum of 2 unless you install the Modular Electronics hardware option found only in the
SR4A Changes Document.
Firewall - Important if you get hacked, otherwise you probably will forget about it.
Sensors - Important. Replaces your Agility when in VR mode for shooting at things, and when you're looking at stuff through the vehicle's 'eyes'.
But upgrading vehicle Sensors is actually trickier than it sounds.
You upgrade Sensors by upgrading the individual parts. Most vehicles have 4-8 sensors in their sensor package. The overall Sensor Rating is the average of the individual component ratings.
The thing is, most sensor components have a max effective "rating" of 1. Which can make it difficult to raise the vehicle's Sensor Rating above 4, as all those rating 1 components drag the average down.
Handling, Acceleration, Speed - in theory, you want good amounts of these attributes. In practice, you'll not actually interact with them nearly as much as you'd think. Most games simply don't have that many vehicle chase scenes, which is 90% of the time when these attributes become important.
Handling and
Speed are difficult to boost as there's only a tiny handful of options that do so.
Acceleration is a bit easier, as you can get Turbocharging.
Body, Armor - Both important for damage resistance. Unfortunately about the only
Body upgrade is a sidecar that only works on motorcycles, otherwise if you want a larger Body rating get a bigger vehicle.
Armor is limited by
Body. The oddity will be, though, is on average most of your meat team-mates will have MUCH higher
Body/Armor ratings than your drones. You regularly see street sammies running around with 24-30 dice pool for damage resistance, while that poor Steel Lynx is probably at best has a 12 or so. The only saving grace is that vehicle armor is effectively Hardened - but that only becomes a factor on the big vehicles that can afford to pile the armor on. Most drones are just screwed.
Which leads to a related point. Since drones, counter-intuitively, have WORSE defensive ratings than meat shadowrunners, they will get damaged. A lot. Better invest in Mechanics skills.
Autosofts:Most of these are only used when the vehicle or drone is in autonomous mode. They'll need the autosofts in those situations because most vehicles have piss-poor base attributes for any tests on their own, so every dice pool boost helps.
Clearsight, TargetingMust haves. These should be loaded at all times. Sensors as noted can be difficult to upgrade much, so a drone needs
Clearsight to boost that dice pool otherwise it can't even see things.
Targeting helps the vehicle hit stuff when it does see the target.
Adaptability, Maneuver, Chaser, Covert Ops, Defense, Encrypt, ECM, ECCM, Electronic Warfare, Profession, Trailblazer - Situational. You won't need these all of the time, but they come in very useful when you do need them.
Adaptability helps if the drone needs to make decisions on it's own a lot.
Defense is only used in melee combat ad Full Defense actions.
Maneuver and
Chaser usually only come up if you're in a chase or attempting tricky stunts. Most vehicles won't be able to make use of
Covert Ops all that much since they tend to be kinda big - drones are the exception, especially if you get them Chameleon Coat and other masking hardware.
Encrypt,
ECM,
ECCM, and
Electronic Warfare often never come up in many games at all, because many GMs don't want to bother with the hassle, but if your GM likes hacking your drones they're your shield against it.
The others, well, you won't see too much use during games. Though, if you have a couple drones kept at home base with
Profession (Auto Mechanic) loaded, they can fix and modify stuff for you while you're busy shadowrunning. Better get those drones high Pilot & Adaptability, as well as the Fuzzy Logic hardware upgrade, though.
