Custom
The pervasiveness of technology goes hand in hand with the ability to tweak and alter that technology. Engineers build custom refits for vehicles, and hackers jailbreak personal communication devices to do things the original creators never intended. Custom technology can be any piece of technology described above but with numerous modifications that make hacking or disabling it much trickier. The DC to disable or hack into an average piece of custom technology with the Computers or Survival skill varies, but it might be as high as 40.
