Dummy

Dummy is simple protection/utility program that can be reconfigured to duplicate almost any program on the market today. Dummy can be activated before a run starts, and will hover about the user's ICON until primed. When primed (with an Average Programming roll), it will take the form of almost any program. Dummies are used by Netrunners to confound users and Monitors (Monitor has to roll versus the Dummy's STR, but gets a +2 on the roll), and by Sysops to make their DataFortress look a lot nastier than it really is. Dummies can threaten, but cannot (obviously) attack SeeYa and Hidden Virtue will identify Dummy as being disguised.
