Hint :
Hint: Easy money:
Use the "$50,000" code, then go to the Bot Lab. Make a robot with a flag and an ax on top. Go to custom challenge and battle Aquarius in a flag match. Bet $10,000 and begin the game. Go behind him and attack his flag. When you hit his flag with the ax you will win and gain $10,000.

Hint: Over limit bot:
To make your bot go over the limit, first buy the tiems you want, except armor. Do not go over the limit yet. Then, buy armor that will make you go over the limit.

Hint: Updated opponents:
Build up a lot of money before downloading the v1.0.0.3 patch, because the opponent robots will be supercharged. For example, Zombie now has two chain saws in the front and Urban Menace has new wheels and two knife blades that poke out in front of him. You will also have new robot opponents. Some of them include Topknot, an updated Gammaraze, ScooterPie, Sixpack, Pontoon, and Triclops. It is a good idea to win tournament mode before you get the patch, as there will be nine robots instead of seven and the dollar values are lowered for winning a match. You will also get a new weapon, the chain saw.

Hint: Change sounds:
Note: This procedure involves changing a game file; create a backup copy of the file before proceeding. Before starting the game, open Windows Sound Recorder. Select "File" and go down to "Open Or Load File" then search for the "Robot Arena" folder and open "Sounds". Right click on the sound that you want to change, and click "Play". If that is the sound you want to change, double click it. This should bring you back to Sound Recorder. Go to "Options" and go to "Delete After Current Location". Press "Record" and make a sound . Replay it, and if you like it, save it. Play game and if done correctly, you should hear your sound rather than the original sound.
