GoldenEye 007/Dam

Neutralise all alarms (Secret Agent, 00 Agent)
There are 4 alarms on this level which must be destroyed.

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.

Install covert modem (00 Agent)
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 Ourumov (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 slect the modem from your inventory and fire it onto the computer.

Intercept data backup (00 Agent)
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.
