Level 15--Desert Railroad

You begin in a boxcar with two switches. Activate the switch with a handle to open the east door. The train moves west, so east is towards the back.

Jump diagonally right to the next car and interact with the door to open it.

In the hall with three doors, run down the left side. At the third door, draw your pistols and shoot the first assassin (1) as he enters from the left. Defeat him using the method of holstering, drawing, firing 3 shots, and repeating to avoid damage.

Enter the first two rooms to the east. Shoot the wooden crates (18, 19) inside to break them. Collect the small medipack (237) and red shotgun shells (238) from the first room.

Enter the third room and shoot the empty crate (20).

Continue east, open the door, and jump across the coupling to the car with the blue tarp. A cutscene (a non-interactive cinematic the game plays automatically) will show 2 assassins (2, 3) jumping onto the flatcar ahead.

Use your Uzis to quickly defeat the assassin on the right as he jumps or moves. Then, use your Uzis and shotgun to defeat the assassin on the left.

Jump onto the flatcar, run to its end, and make a standing jump/grab to a ladder on the front of the next yellow boxcar. As you pass the hatch, an assassin (4) will emerge. Simultaneously, another assassin (5) will emerge from a hatch on the next boxcar east.

Equip your shotgun, run past the hatch to trigger the nearest assassin. Roll, look, and use your shotgun to defeat him while he is climbing and vulnerable. If he runs west, eliminate him before he is out of range.

Equip your pistols and run east. Carefully walk to the edge of the car. The second assassin should be in his defensive stance. Use the strategy of holstering, firing 2-3 shots, and holstering again. If he charges, he becomes vulnerable. If he draws his Uzi, you can take damage or reload and try again.

Head back west and drop through the open hatch on the first yellow boxcar. Crouch and shoot the low crate (21). Collect the 2x red shotgun shells (239, 240) and the small medipack (241).

Equip your pistols and proceed east. When you cross a white line, another assassin (6) will appear. Hop across the line and back. Fire your pistols while dodging him until he enters his defensive stance, then defeat him using the usual method.

Continue east and make a standing jump/grab to the ladder on the front of the second yellow boxcar. Pull up and go past the open hatch.
