Uncharted 2 Among Thieves Chapter 25 - Broken Paradise

This chapter will begin quickly, so be ready to run from the outset. You're not only dealing with the indigenous people here, but with enemy soldiers as well. So, everyone will be shooting at each other, and since you're unarmed, you can't return the favor. For the time being, all you have to do is run forward, climbing and jumping as you go, moving as quickly as possible. Eventually, the platform you jump over to will fail, and it will crumble and begin falling to the ground. It's at this point that you can arm yourself with an assault rifle, and either dodge or fight the enemies on the platform with you. When the platform crashes, any remaining enemies will die, and you'll be free to progress.
