Spoiler Alert: This post is filled with spoiler stuff. If you're new to the game, go play for a while. We'll wait.
Anyway, if you have the Electrician skill, you can offer to gather up 3 iSlabs for Hatter in exchange for the DMC pass.
Does anyone actually take this route? I've tried it a couple times. I've never succeeded. By the time I find a second iSlab and get in back to the city, I've enough cash to just buy myself a DMC pass. And there are other, much easier options. (Why would anyone not take Trapping?)
Maybe I'm just unlucky in tracking down iSlabs. Maybe I'm missing something. But right now it seem the iSlab route isn't very useful. Either it's too difficult, or the other routes are too easy. I'd like to hear other people's opinions on this.
