WHAT YOU SHOULD KNOW: GM Screen's as we know them are fading fast. There was a Savage Worlds GM screen a while back that was clear plastic panels that you could slip cardboard panels for the game you were running in. The Interface Zero GM screen is along those lines...a "do it yourself" GM screen. The three art panels consist of some gorgeously thematic art, running a decent range of IZ material, including an android, cyborgs and mercenaries...(and a cyberpunk street samurai looking figure). The three rules panels include the Gritty damage rules, Zeek fatigue and the Hacking 2.0 rules.
WHAT WORKS: Great art, all the relevant IZ setting rules...about what you would want from a GM screen.
WHAT DOESN'T WORK: It feels a TAD cluttered...but there's just a metric crap ton of tables on this thing (all relevant to your needs).
CONCLUSION: Unless you hate GM screens, this is a very good pick-up for $3 if you have access to a good printer. Much better deal than the $20 GM screen standard we've seen in the past, especially if you have one of the clear Savage Worlds screens to slide the panels into.
