If we are indeed going to be in Hexagon for Underrail 2, I think it's safe to assume some kind of implants/cybernetics will be available. We could also assume since we'll be in north underrail we will also be able to get to Dis as some point, so we'll have access to all sorts of things.
I think there should more of a gradient type system to implants/cybernetics. For instance, you might spend 30k on a high-end implant that is installed by someone who knows what they are doing. Minimal risk of a botched job, and top-tier performance.
If you're a little pressed for cash but still want an implant, there are still options. You might go to "a guy" someone knows who'll do it for cheap. One-thousand, he says. In this scenario you're dealing with an amateur and sub-standard equipment. It's possible everything goes well and you get a small boon, but it is a dice roll on whether or not you get injured, or even killed in the process.
Of course within the two extremes there are also plenty of options. Reputable dealers and installers who offer quality upgrades. They typically run in the 5 - 15k range.
You'd also have to carefully decide on what implants/cybernetics you get. If you spring for the higer quality parts and installers, you can get away with becoming half-machine. If you skimp out, your body may only be able to take being hacked apart once or twice, depending on constitution.
