From the introduction:
The adventure starts with a lucrative offer.
The team receives a “Special Client Christmas Magic VIP Mega Bonus Discount Coupon”, which can be redeemed in nearest CyberProsthesis clinic – the place where your punks usually buy their implants. The special discount program is suited for “professional clients, who are most valuable to CyberProsthesis”. Or so the coupon says. Each member is allowed to purchase one particular cyberimplant with 60% discount. Just make your players feel important. Hint that due to their past performance, they are now recognized and respected. Naïve fools.
The offer should be suited to whatever is jacked in your characters, i.e. punk with cyber-eyes can buy new optical implant, the guy with mechanical legs can get a new pair and so on. New implants are of a very good quality, not cutting edge prototypes or military grade mass destruction devices, but cool stuff nonetheless.
The offer is eligible until Christmas, so your punks should hurry and grab whatever they want for cheap.
