## Secrets

1. When you emerge from the brown, flickering hallway into the green tunnel with the sewage stream, hop over to the other side and open the black grate just to your left.
2. Just past the previous secret, destroy the fan vent on the right wall and use the crate to help get in there. At the bottom of the path will be a single panel of duct wall that is clean, which you can destroy. Do so and head on through.
3. Following from the previous secret, head down the stairs into an area with a pool of water against a back wall with vines hanging down. Jump on the ledge of a nearby pillar and then jump over the right side back wall into a hidden alcove.
4. Inside the room with the Blue Access Card, go into the security office with the window you can block off with a metal shudder and open the brown safe on the back wall. Then open the back wall inside the safe.
5. You will eventually come to a room with "Gate A" and a "Gate A Control" switch. Just down the stairs across from this switch & door is a green pipe on the floor with a niche in the wall you can crouch into. There will be a crack in the wall on the right at the end of the path. Blow it up and head on through to find the TMNT's hideout!
6. When you get to the hub room where you see signs showing you have to change the water and air levels, face the signs and turn left, going around to the back wall with two grates on the wall. The left one, despite having no visible blemish or crack on it, can be blown up.
7. From the hub room, head to the left "Water Control" area. When you reach a giant valve upstairs in this new area that has a "Gate A Control" sign above it, turn around and face the section of wall with the biological hazard symbol on it, jump on the railing to give yourself the height you need, and jump through the symbol.
8. From the hub room, head to the right "Air Control" area. When you get past the air fan puzzle to get to the further away ledge where you need to go next, immediately turn right and head that way until you see a vent on the left wall. Go through it; you will come across a see-through grate with the secret items on the other side that you cannot break through. Instead, inch back inside the duct to where you can stand up, face the panel of duct wall that is cleaner/brighter than the others and jump through it to reach them.
9. After solving the water and air puzzles and using the fans to get into the purple pipe across the water from the machinery, fall to the bottom of the pipe and look right; there is a discolored section of pipe you can open and head through.
10. When you get to another hub-like area further on, in "Level B3", at the end, you will come to an office where you have to turn a purple valve to open "Sector B" of the underwater tunnels. In this room, back on the first floor, there is a slightly recessed, two-tone section of wall under the "arch" that can be opened (mind the Diopedes!).
11. Near the end of the level, you will climb a ladder and emerge into a blue-hued room with a giant fan vent on the wall, with the secret items behind it, guarded by some Cysts and Pustules. Go into the hallway on the right and look for a brown generator/panel on the left wall. Lower it, and go through the vent to get to them.
