Evolution is the second chapter of the third act in Gears of War.


Keep your distance from Dark Wretches.

The path branches left and right, with a door on each side. The first one you attempt to open will be locked, so as soon as you press the switch, immediately head around to the other side. There is a bathroom stall in the left hallway, however, with a small ammo cache. Continue through the building until you enter a room with a brief yet horrifying flashback cutscene, showing an entire group of Stranded massacred by Lambent Wretches.


Starting the Chapter.

The doorway to the right is locked and requires a security code, so for now open the door to the left. Just beyond the door is a man that'll help you unlock the door on the other side of the previous room. You'll move through a series of halls while following the stranded man before heading downstairs to hear his gruesome fate. At a couple of points, Lambent Wretches will jump out while following the Stranded, it is best to let him take care of them in order to preserve ammo because he can kill them in one shot with his Gnasher Shotgun.


Don't let that happen to you; it would be unfortunate if that happened.

The floor ahead is very unstable and you'll join the Stranded in the pit below if you don't move forward with caution. Pay close attention to the noises of the boards under your feet. If you step onto a board that'll fall, you'll hear a distinct crack (and feel a slight controller rumble) that should warn you to immediately back up. The boards that fall are randomized. Make sure to stop by the far-right corner of the room for a set of COG Tags. If you do fall, run around the edges of the room; eventually you'll find a door leading to a ladder that will allow you to retry the board maze. Kil any Wretches down there too, since the constant attacking can kill you on Insane. Waves of Lambent Wretches will continue to attack until you reach the other side.


The COG Tag at the upper right end of the room.

After hitting the next checkpoint, you'll enter a large, cluttered room at the far end of which is a pack of Wretches, waiting to ambush you. As soon as you see them appear, start backpedaling with your shotgun at the ready. Remember to back away from killed wretches (they still explode!), and watch your back for any creatures that try to come at you from behind. On the Insane difficulty, however, it is almost impossible to survive the attack by staying in the room. After killing the first Wretch that is hurtling towards you, run all the way to the end of the room where you saw the first Wretch call his buddies out. This will nullify the spawning of the other waves of Wretches, and will help you clear the room faster. However, the space in that room is rather cramped, so stay on your toes and don't get killed. When the room is clear, continue to the other side to enter another narrow hall.


Opening that door.

Just around the corner is a room with a valve you'll have to turn in order to open the heavy metal doors. Watch for a lone Wretch that appears out of thin air when the lightning strikes as you make your way forward. You will finally meet up with the other two members of your squad. Continue forward and be ready for the act's first real firefight.


Trying to open the door.

Locust will come from the right, accompanied by Wretches that swarm you from the front and back. Hang tight with your squad to fend off the enemies before making your way any further through the large room. At the far end of the room is a doorway you can try to open. You'll fail, at which point a small lift to the left drops, releasing a Boomer accompanied by two Grenadiers. If you have the Longshot handy, fall back as far as you can and take cover. If you feel confident, go ahead and take a shot at the Boomer before the lift comes down all the way. After he's dead, finish off the Grenadiers.


The end of this chapter.

If you don't have a Longshot, stand back and lob grenades into the elevator enclosure while it drops to soften up the enemies inside. You should be able to escape scar-free as long as you keep your distance. When the brief firefight is over, go through the doorway that's just been opened and proceed to the next chapter, Coalition Cargo.
