Complete the game to unlock the Double Chainsaw, Katana, and Hard difficulty.
How to defeat Death Blade:
To defeat Death Blade during the first challenge, run around him until he swings and misses. His face will light up when this happens. Attack with the chainsaw while he is recovering.
You can only get Ultra Violence with the zombie. To get Ultra Violence, grab the zombie and use the human garbage can. Do not finish it. Allow it to regenerate and repeat the process until you get Ultra Violence.
Get to upper level in the Mad Castle:
To get to the upper level in the Mad Castle, jump on the boxes stacked up near the saw room. When you get to the top, dash down the hallway or you will die.
Asian Town coins:
The coins can be found in the following locations:
COIN – LOCATION
Coin 1 – Located in the Dragons mouth. To get it, go to where the money shot is found and walk on the dragon until you make it to the head. Press A.
Coin 2 – In the room where the meat grinder is located, go to the elevator. Kill all the guards on it. Defeat Yuu Fung to get the next coin.
Coin 3 – Stay on the roof and look for the grapple point somewhere on the corners. Slide up the grapple and kill all the enemies at the bar. The bar produces a constant supply of meat buns so you can distract the enemies while you fight. Kill all enemies and grab the coin before it gets to the other side.
