Despite the fact that this chapter is much shorter than previous one, our brothers will get special tasks. Thomas, except for helping Ray two times, will be asked to cover Ray while he will be setting charges.
He will be forced to do this activity near the end of the chapter, after reaching the top of the mountain. When Ray will go behind the rock to set dynamite, try to kill enemies who will start shooting towards him. If you do not do this he will die.
The best vantage point is behind the rocks, you will get there going around that obstacle from the left side.
Ray's task is limited only to the one activity. You will have to set dynamite on the rock at the end of the chapter.
Being on the top of the mountain at the end of the chapter, the game will ask you to set three chargers in pointed out spots. During that action be aware that enemies from the bottom can shot you so try to do this as quickly as you can. When all explosives will be fixed to the rock you will get 10 seconds for escape. The explosion is the last thing in this chapter.
