At the Main Menu, choose the Options Screen. From there, press the X button on Game Status, choose your player with X button and then press the L1+R1 buttons simulaneously. From here, enter the code. If done correctly, a voice will say, ''Funky''. Note that each time you complete a code, you have to press L1+R1 again to enter a new one.
To unlock the original Vigilante 8 levels you must start the game in any mode then pause the game, but you'll need the original Vigilante 8 game. Open the lid of the PlayStation without turning the power off, then remove the Vigilante 8 Second Offense disc, then put the Vigilante 8 (first game) in then close lid. This should take about 10-15 sec. then should say V8 Levels Enabled. Then take the game out and replace it with Second Offense. Then exit and return to the main menu. When you start any mode other than quest mode the original levels will be available.

Alien
In the Arizona level, blow up the observatory and you should hear and big BOOM. GO to the crater in the center and there will be a meteor in there. Blow up the meteor and a giant ant will come out and shoot everyone. Kill the ant and another meteor hits. You can do this as long as you want.
