Superballs

Superballs is a distraction program designed to overload a deck's net-object tracking routines. Simply put,. the program generates thousands of objects in the tracking space of a netrunner's icon. This forces the 'runner or target system to attempt to re-align its tracking routines (or, in the case of a 'runner, ignore the superfluous virtual objects). Roll 1D10 and add the system's INT ('runners add their INT and Interface); on a 15+, the program's effects are ignored for that tum. Test every tum until the program is canceled or destroyed. If the program has an effect, the subject receives a -3 to initiative for that tum.
