Go forward through the corridor which will lead you to a locked door. You will reach a monitoring room, where you can listen to another message on an answering machine and enter another corridor filled with crates.
After clearing the corridor of various enemies, destroy the crates blocking the wheeled scaffolding and push it towards the wall to be able to climb up.
Shoot the pig on the crane and jump down through the hole to the room below you.
Listen to the message recorded on the answering machine on the desk and go to the main hall.
Your task now will be to weight down the boards hanging from the crane, so that it leans to the other side. In order to do that, you have to find the blue barrels.
After throwing the first one which is right beside the crane, a lifter will enter with a bang and a group of pigs will come in.
Get inside the lifter and drive it below one of the scaffoldings co that you can get onto it and take the barrel from it.
Afterwards place the lifter beside gate number 1 and take the barrel from high above.
Once you throw the barrel onto the crane, more enemies will come in through gates number 2 and 3. After eliminating them, you will find the last barrel behind gate number 3.
After throwing it onto the crane, two flying fatties will fly into the hall. Luckily the pigs you were fighting before left behind lots of RPGs that will come in very handy. After defeating the Commanders, get onto the crane using the scaffoldings and further downwards the tunnels.
