Psychodrome

Psychodrome is anti-personnel program employs a radical new approach to electronic counter-intrusion. Psychodrome does not attack the netrunner's body, but rather his mind: via its Bloodhound subroutine, it uses a direct sensory feed (like that of braindance) to fill the netrunner's mind with scenes/sounds of shock and horror. If successful, the immediate effect is unconsciousness for 1D6 hours, plus a lasting side-effect. When a 'runner has been hit by Psychodrome, he must make an Average COOL roll once per day, or he cannot face returning to the net. When the netrunner makes the roll, he has overcome his trauma (until the next time he encounters the Psychodrome). The program is usually disguised as a code gate, memory unit, or other innocuous system location (sysop's choice). If keyed to the psych traits of a specific netrunner, its strength is 5 instead of 4.
