Clear the initial few rooms until you find the Silver Key door; go through the door to the right of this and you'll find a darker stone colored bridge in the next room. From this bridge jump across to the area with the Double Barreled-Shotgun and go through the doorway. Keep following the path until you find the room with some yellow armor; shoot the switch on the far side of the wall and jump up to collect the armor.
If you keep following the path you're on you'll find the Silver Key. A door will open up giving you fast access back to the locked door that we need to open. Defeat a few more enemies, step on the floor button in the next room and defeat the enemies. Follow the straight path to the exit.
Secret #1
Secret #1: At the start of the level go into the water and shoot the wall on the right side of the bridge. This will reveal a secret tunnel. If nothing happens when you shoot the wall try another, it's not difficult to find.
Secret #2
Secret #2: Go up the set of stairs across from the Silver Key door to find a hallway with checkered flooring. On the right hand side of this hall there is a thin pillar which stands out; press the button that's under the torch and you'll reveal a cubby. Inside the cubby you'll find the Quad Damage power up. Save this for later in the level if you're playing on a harder difficulty.
Secret #3
Secret #3: In the room where you need to shoot a switch to hit the yellow armor you'll want to fall into the water. Approach the wall with the switch on it and a secret door will open up, use the teleporter to get back up.
