* Hint, More experience : Begin game play and reach mission 2. Get the baseball bat from the opponent that is on top of the fence. Next, jump off the fence and let the two thugs come after your character. Get the top thug to come to the end of the red pipes at the top of the screen. Once he is at that location, run up the fence and move all the way to the end of it. Then, turn around, jump back off the fence, and go to the end of the pipes. Although no opponents will be in sight, start swinging your bat at the end of the pipes for more experience and faster move learning.

* Additional moves : Accumulate 1000 experience points, as noted in the counter the bottom left corner. One additional heart and a new move (in the following order) will be awarded...

Level 1: Left/Right Punch, Kick and Head-Butt (starting set)

Level 2: Uppercut and Roundhouse kick

Level 3: Jump kick

Level 4: Hair pull

Level 5: Pin attack

Level 6: Elbow punch

* Hint, Defeating Chin easily : The level two Boss, Chin, can be defeated by quickly climbing down the ladders after he appears. Keep climbing downward until the end of level music is played.
