Maximo vs. Army of Zin PlayStation 2 Cheats

Monty Python Reference
Sometimes when you see a breakable tree stump there will be a little rabbit nearby. If you hit it, it latches on to Maximo in a way that is reminiscent of the 'Killer bunny' scene from Monty Python And The Holy Grail.

Infinite Goodies
On Level 9, Down with the Ship, you have three minutes to destroy six reactors. Using the Drill Attack, you can destroy a reactor with three hits. Destroy five reactors, then spend the rest of your time fighting enemies. You can earn lots of money destroying enemies. When time is almost up, destroy the final reactor. Go back to Level 2. Purchase power-ups and continues from the merchant then save and quit the game. Load your save, return to Level 9 and repeat the tactic. You can do this as many times as you like and earn oodles of cash in the process.

Rewards
If you would like to Master every stage, you will have to do the following: save all of the lives of the Innocents, find every one of the buried Treasure Chests (Secret Chests), collect every item in the stage (Koins, Diamonds, Armor... Everything, basically), and defeat every enemy in the stage (including those Evil Bunnies.) If an enemy falls off of the stage, it is counted as a kill. If you collect an item and die, you will have still collected the item. You will be rewarded with Art Galleries of concept images.

Easy Money
You can replay any level that you have previously completed as many times as desired. To get as much money as needed, replay an easy level, collect all the money, and save the game at the end. You will now be able to buy any of the upgrades that you need from the salesmen.
