The L1 + X is the knife attack, R1 brings your weapon up to ready for fire, R2 is to tell Ashley to "wait" or, "follow me", R1 + X is to aim and fire the weapon, R1 + the square button is to reload, The "start" button brings up your weapons case, and sub screen,The "triangle" button opens your map, By pushing "down" and "square" you can turn around fast, this comes in handy when something is real close to you. On your directional button...push up, and the square button to run. Hope this gets you started...good luck! believe me, you are gonna need it!
I've played resident evil 1,2,3, and am almost finished with 4. Nothing is cooler than turning off the lights and getting submerged in these games!
