Evolution
Find an Alternate Route
You call the rest of the squad, to find they found a way in to the basement of the facility. Anya informs you to find the Cart Control Room to use the carts to gain access to the mine.
To move out of this room, you need to activate the switch at the end of each hallway.
Find the Cart Control Room
As you progress, Baird finds a way to turn on the lights. Just your luck as you get to see a room filled with Stranded corpses strung about after being a meal for the Dark Wretches.
Inside the next room you come across an ecstatic Stranded who thinks you are his rescue team. Lucky he knows the facility well and can guide you down to the cart control room.
Continue to follow him, but watch for a Dark Wretch or two that may pop out of the walls or vents to attack. Eventually you'll reach a room with a wooden plank floor that isn't very sturdy. He will fall through and be eaten by the Dark Wretches below.
Just past that room you will reach the mine cart room, that fills up with about ten nasty Dark Wretch. Take them out quick and avoid going into cover.
A room ahead on the right will contain a valve that you can turn to open the doors. Once behind those doors you will meet back up with the rest of your squad. You may want to have them take a shower first though. Open the gate with the valve on the wall.
In this next area, all seems well until the squad spots a Dark Wretch on the ceiling. After that all hell breaks loose. You have some Dark Wretches along with Drones and Grenadiers to clear out. You have the whole squad back together, this shouldn't be too hard.
Once they are cleared out, you find a door to break through at the end to get to the control room. It's stuck shut, so Jack needs to open it. Too bad a Boomer has just decided to drop in on you. Take cover and take out the Boomer and the Grenadiers he brought with him. Toss a few Frag Grenades ever so carefully at their feet as the elevator touches down. You can find them on a stair ledge in the opposite side of the room.
