Hints
Level 2: Skip robot Boss
Play level two (Wayne Enterprises) and after about
two to three elevators, defeat all the enemies to get the key.
Then, walk past the elevator. You should find two more easy enemies
guarding two metal creates. Defeat the enemies, break the crates
(you must have the Offensive Suit) and go through the door. You
will find a room with a bull enemy in it. If you have the Nimble
Suit with you, Double-Jump onto the cabinet in the room and collect
either an extra life or a full health bonus. After you defeat
the bull, go to the elevator and you will arrive in the room after
the robot Boss.
Level 3: Block toxic breath
You eventually encounter snake enemies with toxic breath
that does severe damage to your health. However, if you have the
Defensive Suit the breath will stop at the bat-shaped shields
and will not affect your health.
Defeating the Joker
When you reach the Joker, equip the Defensive Suit.
After that, constantly ram him with the Shield Punch. He should
go down after about fifteen hits or less.
