Blink

Blink is a product of a deranged Al. using a "fuzzy logic" process, the program scans its target and swiftly assembles a set of code that will (one hopes) combat the target program, which can be any sort of ICE (Blink contains Anti-program, Intrusion, And Decryption routines). It does 1D6 STR damage to programs and data walls and goes through code gates, if successful. Blink is not too reliable, though—it has a tendency to "stutter" (just short of crashing the CPU), corrupting onboard programs and files as it does so. When using Blink, roll 1D6. On a 4-6, it works fine. On a 1-3, 'runner loses that many MU of programs and files, at random!
