I'm having a hard time understanding what the matrix attributes for a drone/vehicle are in 6e.
I understand that the Sensor rating is the same as the Device Rating, and that in 5e the Device Rating was used for any Matrix attribute that wasn't explicitly stated for the device, but it doesn't say that anywhere in the 6e rulebook that I can find and instead says "If the device doesn't possess one or more of the Matrix attributes, then the applicable attribute is treated as if it were 0." (p174)
So if I have a Steel Lynx Combat Drone, is its Firewall stat 4 (equal to its Sensor stat), or is its Firewall stat 0?
