If you want to play ICE like Bill, keep the following quotes from Neuromancer in mind:
With his deck waiting, back in the loft, an Ono-Sendai Cyberspace 7. They’d left the place littered with the abstract white forms of the foam packing units, with crumpled plastic film and hundreds of tiny foam beads. The Ono-Sendai; next year’s most expensive Hosaka computer; a Sony monitor; a dozen disks of corporate-grade ice; a Braun coffee maker.
See? So my obsession with cassettepunk is pretty much spot-on. Ice on disks… how on earth can something as powerful and dangerous as ice fit on twelve disks? Simple. Here’s the reason:
“Just thinking out loud . . . How smart’s an Al, Case?”
“Depends. Some aren’t much smarter than dogs. Pets. Cost a fortune anyway. The real smart ones are as smart as the Turing heat is willing to let ’em get.”
“Look, you’re a cowboy. How come you aren’t just flat-out fascinated with those things?”
“Well,” he said, “for starts, they’re rare. Most of them are military, the bright ones, and we can’t crack the ice. That’s where ice all comes from, you know? (…)
“You got it. Corporate core data for Tessier-Ashpool S.A., and that ice is generated by their two friendly Al’s. On par with anything in the military sector, looks to me. That’s king hell ice, Case, black as the grave and slick as glass. Fry your brain soon as look at you. We get any closer now, it’ll have tracers up our ass and out both ears, be tellin’ the boys in the T-A boardroom the size of your shoes and how long your dick”
Ice is made by Artificial Intelligences. But it gets better:
Case sighed. “Well, I got a user-friendly Chinese icebreaker here, a one shot cassette. Some people in Frankfurt say it’ll cut an Al.”
Ice on cassettes. Of course. I know Godfather Gibson probably didn’t mean it that way, but that’s my selective interpretation of the source.
And ice can be brute force, or really sneaky:
“I did, once. Just an idea, back then. But that’s what ol’ Kuang’s all about. This ain’t bore and inject, it’s more like we interface with the ice so slow, the ice doesn’t feel it. The face of the Kuang logics kinda sleazes up to the target and mutates, so it gets to be exactly like the ice fabric. Then we lock on and the main programs cut in, start talking circles ’round the logics in the ice. We go Siamese twin on ’em before they even get restless.”
Another fun fact: You don’t read dozens and dozens of brand names for ice. We know Gibson loves doing that, but NOT for ice, and icebreakers. Ice is monolithic, off-the-shelf, illegal drek hot shit, and so are icebreakers.
Which brings me to a conclusion:
In my cassettepunk Shadowrun games, I won’t be using any brand names for ice, not even different kinds of ice, as both Shadowrun and Cyberpunk 2013/2020/3/Red are doing. Breaking or melting ice will be a single die roll, or, if it’s really tough, several dice rolls. The hacker/decker MUST be successful in every single roll, or the ice will do horrible things to him and/or his deck.
