Okay, here's a first draft of what I'm calling the "Matrix opposition sheet".
This isn't much like the Cyberdeck sheet. It's really meant to be printed off and used once by the GM for an individual encounter by a hacker against a host, another hacker, etc. It's where the GM can track the rating, attributes, O.S., and other notes pertinent to this particular encounter. Honestly, you could just scribble this in your notebook, but I like having a few rules handy (particularly for O.S. and convergence) on the sheet as well. As you can see, there is a column on the side to track O.S. as it goes up and down. There's a section to jot down security procedures, such as what the host/device does once it detects a hacker, and what IC it has and in what order they will load. And lastly, about half the sheet is just lines for the GM to track all the various notes, like the status of any security spiders, what devices are slaved to the host/device, what files are there, if they're encrypted or bombed, and a place to track marks.
Condition monitors for IC aren't on the sheet, since I have cards for that. There's a monitor for any device being directly hacked (GMs can also track that with tallies in the notes section, of course). The GM can also track loaded programs and/or IC with the cards I've created along the bottom/sides of the sheet.
Anyway, I hope you find it useful. It's likely to change a bit, like probably shrinking to a half-page and/or including some tables from the Matrix chapter. I'm looking for any suggestions on what to add/subtract/change in order for this to work better for you. Thanks in advance!
