Add the following to the list of Subroutines in the rule named “Tools of the Trade”:

* i - Infection - After a hack replace a Valid Security Measure of the target Corp Name of the Codename’s choosing with a Virus

Add the following to the list of Valid Security Measures in the subrule named “Security”:

* V - Virus - Subtracts ((the number of viruses of this Corp Name-1)*2) from the Defence Score of this Corp Name.

Amend the first paragraph in “Tools of the Trade” to read:

Each Codename has a Tool, which is tracked in the GNDT as a string of characters. Each character represents a subroutine in their Tool. When the Hack Value of a Tool is calculated by a Hacker, it starts at zero and then has the effects of any Valid Security Measures applied to it then of each of its Subroutines applied once in the order that they are listed in the Tool’s GNDT field.
