Gears of War/Act Two: Nightfall

Outpost
Other than Franklin telling you the mission to get to the gas station, there is not much to do here. Just bust through into the house on the left near the fire. Work your way through it.

Cross The River To Checkpoint 1
You and Dom battle your way through the darkness past a few Drones and Snipers. Grab the Sniper's Longshot, you can use it later. Meet Dom at the Ferry to get across the river.

Once on the Ferry you must crank the ferry along the ropes using the A Button. Do this as quick as you can so you can reach the other side while Dom defends you both.

Once on the other side as you approach checkpoint one their lights go out and they are destroyed by the Kryll. Load up on the ammo around this area and continue on to Checkpoint 2.

Get To Checkpoint 2
From here on out, you want to stay out of the darkness or the Kryll will have you for breakfast. To do so, shoot all the propane barrels that you see. This will light up a new area to allow you to travel safely away from the Kryll.

In the first area you will face an Emergence Hole, but the other problem is the darkness. Shoot some tanks to give you light, get close and seal off the Emergence Hole. Or you can be nasty and shoot out the street lights above the Emergence Hole to have the Kryll do the job for you.

Further down the street you will face another Gunner in a Troika flanked by a couple of Snipers, use your Longshot to take them out from behind the abandoned car.

Now work your way down the street by using the propane tanks. Enter the doorway on your left to get into the house.

After you get through the house, a new Emergence Hole opens up in the distance. Ignore it for now, let Dom keep them busy. You should work your way around behind it via the passageway on the left.

Then as you enter the next street, there is a Troika gunner and a Sniper at the end of this dark street. Take the Sniper out by taking out the light above his head. Then snipe the Gunner and clear out any remaining Drones.

To find where you go next, Anya chimes in to use the dark path to the left of the Troika room. To light up that path, get to a hallway window behind the Troika and toss a Frag Grenade into the pathway to light it up. Work through the house while Anya tells you a group of Locust are attacking the rest of the squad.

Once outside, you are faced with some more Locust. Eventually an Emergence Hole opens as well. Find propane tanks hidden behind some breakaway furniture, light them up to get yourself to the Emergence Hole to close it up. It's not easy, so I'd quickly run up after creating a path and toss a Frag Grenade into the hole. Then fall back to wipe out any remaining Drones.

Now you enter an area with a spotlight. Go up into the building and use the spotlight to guide Dom through the street. Keep him lit or the Kryll will get to him. Once he's on the other end, he'll turn on the street lamps to allow you passage.

Take a left at the end of the street, progress until another Emergence Hole opens. Let Dom cover the hole while you flank through the building to take out the hole from the building's north windows.

Checkpoint two is just a little bit further. You need to light one last tank which is hidden under a piece of sheet metal.

Get Through The Ruined House
The Stranded drunkard tells you he'll run the house lights for you to get through to the gas station. Jack stays behind to keep a COM link with him as you progress.

As you go through each room in the house, he will turn the lights on for you. Just be sure to stick to the light areas as you get through the house. All you will really come across here are some Wretches.

Get To The Gas Station
Outside of the house, there is nothing but darkness. If you look ahead you'll see another abandoned car that is movable. In it's backseat is a propane tank. Shoot it to light up the area, but be careful the car is now rolling down the hill. You need to keep up with it by doing a Roadie Run as it coasts towards the gas station.
