问题描述：
Climb down and run back to the fork in the location you just noted and head
the other direction. Pass through the archway and you’ll see a guard
crawling to the left. Headshot him and go to the left. Continue on until
an unseen guy appears on your radar. Turn to the right, look up, and fire
into the sniper head for another checkpoint.
Continue in the direction you were going and pass the flames to your right.
You’ll see a bus to your left and a sniper in front of you. Kill him for
the final checkpoint triggered by a sniper death.

问题解答：
从楼房上爬下来,跑回刚才的岔路口,向另一个方向前进.穿过一道拱门,会看到一个卫兵正向左边慢行.爆头,向左走.向前走直到雷达上显示出一个你未发现的人.右转,抬头,把狙击手爆头,又可以存盘.
继续向前走,穿过右边的火焰.左边有一座巴士,一个狙击手在你面前.干掉狙击手,最后一个存盘点
从楼顶爬下来，跑回你刚才注意过的那个路口，朝另一个方向走。穿过拱门你会看见一个守卫在左边慢慢地走。干掉他以后左转。继续走直到你的探测器上出现一个家伙（你看不见他）。右转，抬头，这时就可以把这个狙击手干掉而且又赚一分了。
沿着你正在走的方向继续走，穿过右边的火焰。你会看见左边有一辆巴士，你面前有一个狙击手。干掉他可以得到最后一个狙击手分（即因杀死狙击手而得的分）。
Switch to your PK-102 assault rifle and round the corner to the right. Head
down the street until you see a bright light coming from a lantern in a
place on the right side of the street. Head in and shoot the guard, then go
out the hole in the wall and climb up to the next ledge. Run forward into
the lighted room and climb down into the hole. Go down the next hole as
well, then photograph the map on the wall for a checkpoint.
Turn to the right and head down the corridor until you reach the next room.
Headshot the guard and shoot the extremely inaccurate guard on the left as
well before turning left and proceeding down the next hallway. Go until you
reach the hallway branching to the left and go down it. Shoot the guard and
access the weapon cache for a checkpoint.
Turn around and stand at the end of the branch and shoot the guard that runs
up, make sure to grab his gun, then turn left and RUN to the end of the
hallway. Climb up the crates one-by-one, not two and one, and run out into
the street and wait for the bomb to explode that you put on the weapon
cache. Wait another second, and Lian will get a comm from Gabe that
precedes a checkpoint.
爬下,回到岔口经营所在地的另一头,你刚才提到的方向发展. 穿过拱门,看到满地爬的守卫离开. headshot,他去左边. 直到一个家伙就不断出现在你的雷达看不见. 谈到有权查阅、狙击手射击到另一头检查站. 你会继续朝向你,并通过正确的火焰. 你看到满地的巴士离去,一名狙击手在眼前. 杀死他的最后一个检查站引发狙击死亡.
