Wipe (Countermeasure)
This program destroys important data.
Resolve: Deceive (DC + 0, 1 success), Hack (DC + 0, 1 success)
Special: Count the number of times hackers fail a check to resolve an obstacle while the wipe countermeasure is active. Once the count reaches 2 failures, this countermeasure begins erasing one or more other objectives, imposing a –5 penalty to resolve them. At the end of the next hacking phase, those objectives are removed from the encounter and can no longer be resolved.
