I had practice at hacking different hub and ring security now, so it was much less nerve-racking to get past the weapon scans. SecUnits are designed to be mobile com ponents of SecSystems, every kind of SecSystem, so the company can rent us to as many different clients as possible, even those with proprietary equipment. The trick to hacking a SecSystem is making it think you’re supposed to be there, and the company had helpfully provided us with all the code necessary for that. Practice and terrifying necessity had made me good at altering it on the fly.
