GoldenEye 007/Dam

General Strategies

 * In the first guard tower on the dam itself, there's a sniper rifle. After defeating the guards nearby, go in the tower, take it, and use it to snipe the two guards in the tunnel nearby (assuming they haven't noticed you yet).
 * In the area after the two mechanical security gates, if you look carefully and quickly, you'll notice a guard in green running towards the area where the first alarm is. This is the guy that makes the alarm go off and have all those guys come after you. If you peg him from afar, he won't be able to set off the alarm, so you won't have to deal with all those bad guys at once. They will, however, still be around in the level, and you'll still have to kill them, but they're more scattered and much less likely to  attack you all at once.
 * On the 2nd tower go down the ladder to the pier. Then go to the end of the pier and press L and R and then you should be on the water. From there get out your sniper rifle and view all the way out in the water and you should see a tower and a jail. From there step all the way over and you'll eventually get there, get in the tower, and find a gattling turret.  Press B and you'll be able to enter the turret and you will be able to figure out it has unlimited rounds and the range is as far as the dam.  So if you haven't killed the 3rd guy you can launch a strike against the guy in the 3rd tower.  you should be able to defeat the guy.

Neutralise all alarms (Secret Agent, 00 Agent)
There are 4 alarms on this level which must be destroyed.
 * Difficulty level: Secret Agent
 * Gadgets used: None
 * Objectives req'd: None

The first is before 3rd main area before - after you wait for the lorry door to open.

It is on the building that the guard runs towards shoot the guard first or he will set off the alarm.

The other three are in the buildings on the dam its self.

Pretty simple. Find the four alarms in the level, and blow them up. One of these is the alarm specified in the general strategies section for this level, and the other three are in the guard towers at the end of the level.

Install covert modem (00 Agent)

 * Difficulty level: 00 Agent
 * Gadgets used: Modem
 * Objectives req'd: None

The place to do this is right after opening the gate for the truck, and opening the fence/garage door. If you do the latter, you will reveal an enemy right before finding a Russian officer (the man with a DD4 handgun). Walk around the outside of this room to the other side of the wall (behind the boxes) where you will see a computer. Push START and select the modem from your inventory and fire it onto the computer.

When you're between those two fences near the end of the level, and after you've blown up the first alarm (hopefully), go to the place where there's all those boxes. On one of the walls there'll be a computer screen. Throw the modem on it. Done.

Intercept data backup (00 Agent)

 * Difficulty level: 00 Agent
 * Gadgets used: None
 * Objectives req'd: Install Covert Modem

Found underground after the area the covert modem is. Shoot the lock to open the fence and run along the dam to any of the buildings on the right side. Go in and under towards the direction you came from.

Go to the guard tower nearest the locked chain link fence. Go in and go down the staircase. Go through the fence at the bottom (it's right nearby), and head to the right through the tunnel, shooting whoever you please (go ahead and  use a KF7, it's not like it'll make any difference in this  hellhole). When you get to the computer room, shoot all the guys in there and go up to the mainframe. Activate the mainframe (B button) and in ten seconds you'll have it completed. Be warned, this is a lot harder than it sounds.

Bungee jump from platform (Agent, Secret Agent, 00 Agent)
Head to the Bungee jump platform and walk off. After falling for some time, the game will transition to a cutscene where Bond does a swan dive off of the platform.
 * Difficulty level: Agent
 * Gadgets used: Bungee equipment (automatically equipped)
 * Objectives req'd: All applicable

At the end of the level, where there's all of those guard towers, proceed to a small set of three or four stairs. Go up the stairs and you'll be on a small platform, with a gap in the fence. Jump off of the platform through the gap. WARNING: Completing this objective will end the mission, so if you're on a difficulty level higher than Agent you need to complete all of your other objectives before doing this unless you want to fail. If you're playing on Agent, though, don't worry about it.
