Begin with ALL Weapons Maxed
The following glitch will allow you to have ALL the weapons and items fully upgraded when you begin a game on any difficulty setting. To enable the glitch beat the game on any difficulty to unlock the 'Challenges of Olympus' feature and then complete ALL 7 Challenges of Olympus to unlock the Combat Arena. Start a round in the Combat Arena on Titan difficulty and if you now die in quick succession the game will ask if you want to switch to Easy mode. Select 'No' and start a game. This glitch is best used immediately before attempting Chaos mode.
