Go right and fight the enemies. Climb higher to reveal the rest of the area. Go left to one of the construction sites. Just move along the road, destroying blue barrels and wooden crates. The enemies will blow up some walls and you will be able to reach the second construction site. Do the same steps. Pick up the first surveillance data package and go to the enemy on the right.
Load the plugins, then move to the left. The Demoman Banbu will start planting explosives. The timer on each of them shows the time until the explosion. You can move explosives. Do this to destroy the walls at the top left and get some loot, including the second surveillance data package. Then move the explosives so as to blow up the banbu itself. He will withstand 4-5 attacks, after which the path to the left will open. You will also be able to plant explosives. To do this, press the R key and select the appropriate plugin in the inventory (there will be only one).
Destroy the walls on the left. It will take more than one explosion. Go to the third construction site, destroy the barrels and defeat the monster.
