Then grab the longer plug from the bottom slot and use it to reconnect the elevator plugs. Use the short cord to connect the top plugs. The bottom one just leads to a broken line, so ignore it. It’s too short for elevator plugs, but the right distance for the main power. Break the wooden pallets by the set of plugs to reveal a short plug. There’s one for the elevator and one for the main power. Get into this back lab and drop down the lift. We need the back room with the single hole. The doors are locked though, so move along the right wall and then climb the little dirt slope and get up onto the roof. We need to get into that big building on the left. The back right house is abandoned, so just ignore it. It seems like we need a little more juice for the transmitter. Then watch while Alyx looks at the equipment. There are 2 zombines in here, so blow them away. Draw your shotgun and then open the blue double doors. Hop out and go over to the first building on the right. Drive along the road until you get to the big gate. Follow it back and then swing around up onto the hill. Like Alyx says, it just can’t be that easy. Drive down the road until you make it to the big wreck.
