Here's what's in my noggin at the moment.
1. Item requirements: Datajack (non-cyberware), Cyberdeck, Netrunning programs (if you want to go that far - I don't know how familiar you are with Netrunning and if/how far you want to go with that). Any items that would boost percentage Skills by any amount (for example, a quality Cyberdeck or even a superior or better Cyberdeck; those damned things almost run themselves).
2. Skillset. Computer Operation, Computer Programming, Computer Hacking. If I were to do this for Snowfall, I would have to ask to replace his most-recent Skill (which is fine if you ask me because I ran out of ideas for his Skills about a year ago).
3. What I'm really going after (and not expecting to get; this would be the ultimate goal): To hell with codebreakers. I'm after data. Superweapon data. I want Lone Star's schematics from top to bottom, left to right. I want guard rotation schedules, maintenance logs, intranet information, anything that gives us an edge. I want to know the best routes in and multiple ways out. I want data we can find and sell (perhaps that leads to other gigs). I want data that Lord Brazamal can use. I want the ability to get it all without the Coalition even knowing it's gone.
1. Depending on how fancy you want the computer deck to be, it will cost upwards of 1 million, because it would be more than just Psy's code breaker. As far as netrunning, there is really very little in the way of an internet or network for you to tap into in most places. The Lone Star complex will probably have a network of some sort, but you'll have to be on site to access any signal. See above for the earlier reference to Psychie's codebreaker for the skill percent increase.Training up those skills certainly wouldn't hurt, and a code breaker computer would add to a Computer Op skill. I will give you a +20% to your skill rolls when using the code breaker, and it will cost you 800,000 and is considered to be highly illegal by the Coalition if you are ever discovered to have it.
2. These skills are fine. You can retrain your last skill and replace it with the new computer one.
3. While it would be great for Dweomer to get access to any of the files in Lone Star, it may be of limited use to them. The Texas complex has top of the line genetics labs, so if the superweapon is a bio-weapon of some sort, Dweomer lacks the basic scientific infrastructure to be able to make good use of it. They focus more on magical powers rather than science.
However, there are people out there that would kill in order to get ahold of any data from Lone Star. These interested parties would jump through hoops to get their mitts on this info.
