About the walkthrough, I wrote it all bellow(without secrets). You may send this walkthrough to anyone you want, provided you mention I created it.

Installation 12

Kill the SAS in the first room and collect the Restricted Card from him. Shoot the box behind the jeep to collect 10 rockets. Head through the push door and down the hall to the truck. Kill the SAS and get the medipack on top of the truck. Don't touch the electric platform in front of the ladder(don't even try jumping for it), she will burst into flames. Head through the next hall and pass through the lasers(Green lasers trip alarms, Red lasers cause death). Kill the two SAS and get the Atlantean Code Disk and grenade launcher. Use the Restricted card in the next hall to open the door, and kill the SAS, collect his Desert Eagle. Head up the stairs and to the left, open the door and shoot the computer that Lara looks at, then continue and kill the dogs. Past the kitchen is a desk with a key on it. Shoot the next computer and get the Fire card from the bathroom. Head back down the stairs where you killed the last SAS and use the Aquarium key to enter the Aquarium (hmm, is that tank explosive?). Past the shark tank head to the left hall and kill the dog in the next room. Move the broken radar machine onto the computer board to open the next door. Kill the SAS and get his Launch card, and the key on the desk. Press the switch on the wall to shut off the lasers in the next room. Head back to the room with three exits and continue to the hall you didn't go through. The lasers will trip two SAS guards, kill them. Head past the Croc tank and kill the next SAS in the next room. Get the medi pack and shoot the box for another medipack. Climb into the air duct and you will eventually come to the tank. Kill the "Croc" and use the Explosives Card to open the trapdoor. Press the button to set of a rumble. Run into the next Aquarium and kill the next SAS and dog, and take his ammo. Use the Key to open the trapdoor in the duct. Head back to the first aquarium to witness the damage done by the explosion. Back in the lab area the two "Crocs" have broken free, use the Desert Eagle to kill them(it can be used while wading). The water allows you to pull the underwater lever in the bathroom near the lab. This cuts off the lasers in the office. The water also allows you to climb that ladder by the truck. Up here open the trapdoor to enter the Air duct. Continue until you reach the room next to the kitchen, and climb back up on the other side. The air duct leads to the office. Grab the Restricted Card from the desk and use the Code Disk to open the duct door. Head back to the duct and crawl through the opened door to end up next to the large room with the truck. Kill the SAS and press the switch to finally open that door near the beginning of the complex. Head to the elevator shaft and climb up to the crawl space to collect the shotgun (getting into the crawl space might be tricky). Head back through that now opened door to part 2, Hanger 12.

Hanger 12

Go into the hall and open the door to kill the SAS, use the Fire Card on the wall to the left (the card hole is actually a texture image). This floods the previous room, open the trapdoor by pressing the switch on the wall. In the water room pull the underwater lever to open the doors in the hanger. On the hanger floor kill all three of the SAS, gat the ammo and grenade gun. Shoot one of the boxes to get the Patrol Unit Keys, then press the switch by the computers to open the door up the ramp. Head back up the ladder and into the previous level. (The game has a tendency to crash while "jumping" back, but for some reason this never happened when I rolled into the finish trigger, very odd.)

Installation 12

Get the jeep and drive though the first door next to the jeep into the Hanger again.

Hanger 12

Drive down the trail and past the SAS to the Hanger floor, drive up the sloped boxes and shatter the supports to drop the trapdoor. Get off and climb up the ladder, jump the platforms to the center lever switch, this opens the next set of doors. Drive the jeep through the opened doors and get off before the turn to open the next set of doors, continue with the jeep to the lower level. Shoot the SAS and past the lasers kill two more and kill the SAS in the launch room. Use the Restricted Card to enter the Pool room. Kill the two dogs. DON'T enter the water, the current will take her to a fan and death. Jump to the rope and be careful not to slide down to far, just so she's touching the water. Jump to the platform and press the switch to open yet another set of doors. Jump back using the rope and take the jeep outside, all the way to the broken truck. There's a medipack through the broken fence. Inside the office is the Launch Card, a dog is in the bathroom. Drive back to the Launch room and use the Launch Card, and find out what it opens up. Now Lara can climb up through the ceiling to the upper level. Kill the two SAS and pull the Lever switch to turn off the fan. Head back with the Jeep to the Pool and dive in. The next room has two dogs and an SAS with some wideshot ammo. Climb the ladder, to your left is more ammo, continue to the upper level and kill two more SAS, and shoot the box to get the medipak. Pull the lever switch to open the final set of doors. Back to the Jeep, drive through the doors and get off to swim into the next room. Shoot the Atlantean statue to release it from stone, use only non-explosive ammo on it. Some of the fire will shut off when you shoot the statue, allowing Lara to finish the level.

I hoped you enjoyed it.
