If you are getting frustrated with a certain League Challenge or Regular Challenge, try turning auto aim on. This is especially helpful in the Outmanned But Never Outpunned levels in the Medium League. For the Someone Has Got To Pay level, keep shooting those ducks and running around to find them. They are programmed to target you so they will find you. Just pin them in and use two shotguns when you get them. The You Can't Handle This level is challenging. Find the room in the Nightclub that has a stage in it. There is only one way into this room. Get two Tommy guns and camp there, shooting them as they appear in the doorway. You may die once or twice, but just get another Tommy gun and make your way to the room. Keep doing this until time runs out. You will then earn Gold/Platinum and unlock Handyman.
