After a short fight with some soldiers you can find some medkits and ammo up ahead.
You will end up on top of dam. A helicopter will be patrolling this area and the end of the road will be guarded by a cannon. No other choice but to jump down the water on the right.
Wait for the chopper to turn around and then climb up the ladder.
Press the button to stop the turbine below.
Drop back in the water and you will find a valve at the bottom. Use it to open the turbine grate and pass through there. You might have to kill the alien swimming around in here first.
When you exit the turbine path you will be on the other side of the dam.
Climb up the ladder and enter the vent.
Climb up another ladder then go left.
Go up one more ladder.
When you reach the sandy area go between some rocks.
Go towards the tower. Be prepared to face some soldiers. Try to avoid open spaces because the chopper will still be patrolling around here.
Inside the tower is the storm drain hatch valve.
Some medkits are nearby if you need them but watch out for the trip mine.
Go between some rocks near the medkits to reach an area with a tentacle alien. The alien is guarding some stuff. You can take them if you grenade him.

And climb one smaller ladder.
Enter the drain canal.

Instead go inside a drain pipe to go around the soldiers.
Climb up a small ladder.
You will end up behind the tank and the soldiers. Time to fight back.
Take some rockets from the supplies near the tank. Then use your rocket launcher to destroy the tank so you can move freely. For some reason the tank can't turn his turret so you will be safe if you stay on his side.
Press the button in the booth to open the nearby gate.
The next path is guarded by an APC with rockets. Use your rocket launcher once again to clear the way.
If you are in need of more ammo and health jump over the hole on the right and face some soldiers. Otherwise continue down the path the APC was blocking.

Go through the gate on the right when you have the chance.

Go down the vent.
Enter a pipe.
The soldiers are expecting you. One of them will throw a satchel charge inside. The explosion will slowly move towards you. You have to back out of the pipe fast.
Hide under the water to avoid damage from the fire. When the fire stops you can enter the pipe again.
