Resistance 3

Replay Chapter: St. Louis, MO: Widowmaker
After dropping down from the gondalla to fight the Widowmaker, there will be 3 sniper rifle hidden around the area that you must pick up without dying. In order to pick up the Deadeyes, you cannot have full ammo, that means the infinite ammo cheat will prevent you from getting this. If you have full ammo without the cheat, simply fire off a shot or two, reload, then pick up the rifle. They are found as follows:

• As soon as you regain control of Capelli, take the bridge to the left, and follow this path until you see a dead body. Near there is a refrigerator and the body of an elderly woman. The first sniper will be near her body, up against a wall.
• Beneath this room is a basement area that is filled with Leapers. Kill the Leapers and the Deadeye will be there on the ground.
• Head north up the stairs, and across the bridge, up some more stairs, and follow the path until you reach an open rooftop. Once in this area, there will be a platform in front of you. Head on up to the platform and use the zipline. This will take you to a small platform above where you began, with the final Deadeye and some health on it.

This must be done without dying. If you die before grabbing all 3 snipers, you will need to restart the chapter. Please see the video below by sunnygrg, for more help:
