I just stumbled upon a shortcut to one of the sequences in resident evil 4. when you get back into the castle after going through the mine to get the stone of sacrifice and you are in the room with the salazar robot, go down to the bridge. when the zealot flips the switch and the platforms disappear under the water, select the rifle(or semiauto rifle whichever one you have) and shoot the lock. this way when you make your way through that sequence and you manage to get to the end of the bridge once it reappears after flipping the levers all you need to do to escape that building is kick the door open.
now folks, this thread does not necessarily have to be limited to the resident evil games and it definitely doesnot have to be limited to the ps2. if you have ANY game hints, tips, suggestions to share, go for it.
