Unlimited Ammo
Players assume the roles of their characters in "Looney Tunes: Acme Arsenal" from a third-person perspective, using both melee weapons and guns to defeat the robot enemies. Ammunition for the guns is limited, but there is a cheat code to get unlimited ammo. Entering the button combination Down, Left, Up, Right, Down, Left, Up, Right and Down in the "Cheats" section of the Main Menu will grant unlimited ammunition to your characters. However, using this cheat locks the ability to save the game, forcing players to replay a level in order to advance in the game. GameFAQs.com recommends using this code only to play previously finished levels.
Hidden Trophy Locations
There are also six hidden character trophies to find while playing Looney Tunes: Acme Arsenal. The Michigan J. Frog trophy is located near a breakable wall near a platform on the Assembly Line Insanity level. The Porky Pig trophy is on top of a tree near the end of Muddy Evil Forest. In Pyramuddle, a box near the swinging pendulums can be destroyed to reveal the Road Runner trophy. The Tweetybird trophy is in the Whack Tastic Robot Bash level above a door labeled "Monster." At the beginning of Volcano Way Out, the Wile E. Coyote trophy is on a ledge at the top of the hill. Finally, the Yosemite Sam trophy is in Low Noon, located on top of a house past the train tracks.
