There will be an option called "Cheats" now.

Get the Alien Beetle
To get the "I come in peace" Alien Beetle, beat the Expert Championship. Once you have completed Metro Madness, you will receive the super-fast rainbow-colored beetle.

Get the Police Beetle
In a nod to the Need for Speed franchise, EA has included a hidden Police Beetle in Beetle Adventure Racing -- but you'll have to work hard to get it. After beating the standard Championships, a new "Bonus" mode will open up. Beat this tough challenge (including Wicked Woods) to get the fastest car in the game, the Police Beetle.

Major Shortcut in Sunset Sands
When racing through the inside of the temple that has exits on both the left and right sides, stay straight - grab a nitro box and jump the pit of lava. You'll land atop a structure with a large red octagon. BRAKE! and stop your beetle over it. Honk your horn and a secret elevator will bring you down to a cool shortcut that will get you ahead of the crowd in no time.

Make Cars Pull Over
Beetle Adventure Racing's computer drivers may take shortcuts and crash into you, but they're still law-abiding drivers. Once you have unlocked the Police Beetle, hold down the left C Button to sound your siren. If you get close, the other drivers will pull over to the side and stop their cars.

Open Up Battle Stages
Most of the game's Beetle Battle stages are hidden and have to be unlocked before you can square off against your friends. In order to get them, you need to enter the Championship mode and try to smash all the bonus boxes on the respective tracks.
You have to collect all 100 points to unlock a new battle stage. All the battle stages are directly based on their track counterparts. Note that it is not necessary that you come in first in the races, but your points are not counted if you are disqualified. Tip: Use the Police Beetle to get the tracks. It's fast -- and you can force cars to pull over and take your time to collect the boxes.

Unlock New Cars
To unlock variations of the New Beetle, such as the Racing Beetle, 4x4 Beetle and "Number 8," simply beat the Championship Mode on Novice and Advanced. Beat the following two difficulty modes for the two bonus cars.
