To get Unstoppable Program you need to get the maximum hit multiplier (30). Go into a Data Station and fire up a Game Grid Match. Disintegration is the default option with Bots. Let the CPUs gather together as they dont seem to care about you at all. Use the basic X,X,X Combo in a large gathering. Some single throws count as 2 or 3 if you are lucky. Keep going until you hit 30.
