Gears of War/Act Two: Nightfall

Repel The Locust Attack
Now Marcus and Dom have made their way back to the Stranded Camp to help out the Stranded and your squad mates Baird and Cole. Head towards the right over the wooden bridge to meet up the Baird. From here you can easily close the Emergence Hole that opens with a Frag Grenade. Stay low though, the Snipers in the building have great aim and will take you out in no time if you get out of cover for too long.

The rest of this level occurs in a different order every time you play it. The same events happen, just not in the same order. There will be two more Emergence Holes as well as a few waves of Snipers to contend with. At one point the game points out to you a loose rock over a pipe on the far building. Use a weapon or the Troika gun at the center of the platform to shoot at the rock to burst a gas pipe open. Fire onto the gas leak to cause an explosion and take care of some of the snipers. From the Troika you should be able to easier to close the Emergence Holes.

A Boomer along with another wave of Drones start to pour out of the building. Use the Troika gun to spray the building with fire to take out as many as you can. Once they are fairly well under cover, take cover yourself and take them out one by one with the Longshot and Frag Grenades.

After they are all cleared out a forth gigantic Emergence Hole opens with three Boomers inside. You can either take them out, or create another gasoline leak using the toppled over gas tank resulted from the hole opening. Once the gas starts to leak out, use the propane tanks as the igniter and you'll get some toasty Boomers.
