What’s this? The Joker and his cohorts have taken over the Watchtower! You’ve got to stop those vile villains, but they’ve enacted some serious security measures. Fly circles around the Watchtower, holding the Attack button to blast through the waves of flying Joker teeth. Keep it up until you destroy them all, checking the progress counter at the top of your screen.
After you wipe out the first wave of Joker teeth, a second arrives, along with flying bombs. Again, simply focus on destroying them all. The third wave features teeth, bombs, and silver turrets poised around the Watchtower. Collect missiles and press the Interact button to launch them at each turret to destroy them.
Seeing his defenses falling, The Joker decides to take to the battle himself (sort of) by sending out a drone that he pilots from the Watchtower. Collect a missile and fire it at The Joker’s drone to knock off one of its hearts. The Joker then speeds his drone around the Watchtower. Avoid him until he slows down, then hit him with another missile. Keep it up until that drone is toast!
