How to find three secret weapons in the game:
Acquire them, beat the level, and they will be added to your permanent inventory.
Grenade Launcher - Choose Zuma Beach as your level or mission. Get off the highway and make your way to the area where you switch to the crowd control camera. In this area you must blow up the two flamingos on top of the hotels outside of the main gate. Then, make your way through the level until you reach the mini-boss (the guy that you will fight just before the boss). After you beat him, a big hole will form in the ground from the explosion. Jump into that and destroy each of the tanks until you find one that has a power up station in it. Go to that and you will get the grenade launcher.
K9 Robo Dog - Choose Venice Beach as your level or mission. Open up the main channel gate at the beginning of the level (where you start out). Go along the channel that you now have access to and eventually you should see three barrels to the east. Go to the west side and turn into the Hover Car. Zoom out into the open and you'll eventually run into the Robo Dog weapon.
Riot Shield Gun - Choose Studio City as your level or mission. Destroy the four control towers, then hit the switch behind the laser gate. Walk over and destroy the first mutant soccer champ billboard. Now, backtrack to the mushroom area. Turn south, then head east. Along the side of the easternmost building awaits the Riot Shield.
