You need to time your disrupts right. Try to use it when the android has full focus to get the most effect, and you don't want him to stun himself with him just got the Force Field activated. Also, try to stun the upper riot police first, the android prefers to help him over the other one. Keep going full defense throughout the fight and only go all out when the android is stunned, blast his health down no matter what. I don't think the police use First Aid on the android so try to finish him off first. Besides, I realized if you use Roald instead of Felicity in this fight you'll do much better, because of the Greater Purpose skill which really helps Veradux in keeping up with the damage. Set Roald to ultra defense if you can to make him cast that spell more often. Wear the android down till you kill him then move to the riot police. Don't let the other police go just yet. Keep stunning him and let Veradux recuperate your team. Finish off one Riot Police and the rest should be easy.
