This level really impressed me because it's big but it's mostly one room. It takes quite a game engine to handle something like that. I had to go back and replay the level recently to remember things. Now it's all coming back to me. Here's a little map of the main room so these hints make sense. Push, don't pull. There's nothing you can do up there... yet. Take a dive. There's a lot of things to grab just by looking around in the water. There's no way to get up to that level with the rat on top for now, so quit trying. Looking for that first rusty key? You'll need to get up to the second floor. The way up is near the ramp. All that hand over hand for that? Ughh. Don't go down to the ground. That first rusty door is full of adventures.=OD Apes and mercenaries, oh my. The falls are worse, so make sure you're using the proper jumps. Yes, you can get to the magnums (hooray! you finally figured out why you've been gathering all of those clips) by a jump from that top platform. I'll give you three clues: it doesn't have anything to do with grabbing the edge, you don't want to stand right next to the edge before you jump and it's a jump you haven't had to use to pass a level yet. If you hang off of the ledge, the crocodiles will come out of hiding. You don't actually need to go down to the floor but if you do watch those dark areas. Look before you hop into that trench. The switch to that door is up. You'll need to backtrack a bit to get down. That guy won't die, trust me. Just get out of there. Time to get up again. This time towards the east end of the room. Don't fall into the water before you find the switch. Rat fights and hopping. You'll need to do a hand over hand to get out of there. Yeah, another rusty key. Things sure look different now. Where'd that 'gator come from, anyways? Good thing you're entering rusty door #2 wet. Be careful swimming around. Time for some deep-water diving. Notice it's a pull-down lever and not a sliding one. With both silver doors open, you're almost done. You'll have to do some looking around for that golden keyhole. You got that last door open and you're still not done. Jeez. Don't stand too long in any one spot on the ground. In fact, I don't recommend being on the ground towards the end of the room until you've taken care of the lions. You could go into the next room, get up and get some stuff. The exit isn't over there, though. It's right under your nose. You may need to move some things, though. If you haven't heard Lara scream by now, you're in for a treat.
