All Too Human
While wasting time crawling the Matrix, the runners spot an interesting job post on The Helix: A fellow Shadowrunner needs an escort to a clinic for surgery. The catch is posted up-front: The clinic isn't expecting him, as the surgery is clandestine. He needs the escorting party to keep him safe while he undergoes the surgery, then break him out again. Mr. Johnson will meet with interested runners in the Matrix, being careful with precise details until the job offer is accepted. His name is Mash, and he's heavily augmented. He says he paid for more high-quality to be cultivated and implanted at a delta clinic, but after a run against the clinic's mother company, the clinic now refuses to give him what he paid for.
Cyberware + Bioware
Mash is a Street Samurai who has on occasion made a good profit, but chose to spend it on expensive augmentations rather than retirement. Quite frankly, he's addicted to the idea of transcending his human form. However, he's reached the limits of what his body can handle. After lengthy studying, Mash figured out a way to enhance himself even further. He had several hackers break into the clinic's systems and program in the creation order of his special project. Now he needs help getting in there before the clinic runs an audit and finds out. The golden opportunity for that has arised with planned Host maintenance. During the downtime, the runners need to get him in and let the autodoc systems perform the lengthy surgery.
The RunNormally, breaking into a delta clinic is suicide. Their security systems are top-notch, with biometric sensors and massively redundant camera footage. However, the target clinic is secretly undergoing an upgrade to their Matrix systems, which means all their wireless systems will be down. The backup nodes can only support a small subset of the security systems, and with the clinic closed physical security is also at a minimum. In other words, the runners must bypass only a low level of security. Best of all, wifi-blocking paint means security cannot call for backup. Even if the team sets off an alarm, they can still deal with it on the fly. It'd be a golden looting opportunity, if only supplies weren't temporarily removed.
Word on the street
"Mash? I know him. Bit of a loner, and crammed with ware. Heard a mage say that he's like two parts removed from death."
"Security will be minimal, giving us the opportunity to retrieve what rightfully is mine."
"Look, mates, our boss is a high-profile target. We're going to need a LOT of insurance to trust you anywhere near him..."
"Memento Mori. Do not worry, my heart will restart in a few seconds. No proper upgrade without some downtime, after all."
