First of all, go into settings by pressing the menu (two rectangles) button on your Xbox controller. Then, in the options menu, select game settings. After that, change, difficulty to LEVEL 1.
Then, before the start of each match, press the menu button and select "Create Interrupt Save Data". If you lost the fight, just exit to the title screen. Then, select Original mode again and retry again on the level you died in. I would advise using the "Create Interrupt Save Data" before each fight.
How to Score Points:
Kick or Punch = 70 pts
Stepping out a land vehicle = 150 pts
Throwing your enemy = 700 pts
Destroying a tall building / radio antenna / stadium / unique building = 1000 pts
* Note = if your CPU opponent destroys a building on their own, you don't get the points.
Beating your enemy with a pin = 5000 pts
Focus on throws to defeat your enemy as quick as possible and destroying as many building along the way. It's the most effective way to gain points quickly.
From what I've noticed, the throw movements are:
- When next to your opponent, press Down on the d-pad / left knob + A button
- When next to your opponent, press Up on the d-pad / left knob + A button
- When next to your opponent, press on the d-pad twice in the direction you're facing + A button
Another thing I earned is that you can shoot a projectile at your opponent by holding down on the right trigger and firing when your CPU opponent gets to you.
With patience, you should get the achievement by the end of level 7 or 8.
