As you start the chapter, there are some rubles and a box of ammo on the shelf to the right. Go down the hallway and go outside. Run down the coast until you reach the camp, but don't miss the briefcase of rubles on the left next to a plank. After killing them all, you'll learn Power-Throw, which lets you do quadruple damage if you time your glaive throw correctly. You have to use it to break off the lock on the gate ahead. Inside the tent ahead you will find an accuracy upgrade and a metal weapon crate, which you can break open with (surprise!) Power-Throw.
