Tips

Play with a friend
Your friend will focus on killing the other cops while you are focusing on killing the shields.

If you play with a friend dont have AI
The AI will try to kill the shields.

Be fast
You have to be fast so you can kill the shields before you get downed by the cops or before the AI kills the shields for you.
