Proceed through the "The Root Of All Evil" level until you leave a cave into a large open area, with a fallen tree at the cave's exit.

Crouch to avoid getting knocked off.
Proceed through the "Post-Human" level until you leave the computer room and enter a large open area. Follow the catwalks to walkways with CELL soldiers.

Use the Predator Bow with the strongest draw to get the best range and accuracy for your arrow. Select the explosive or electric arrow and take down the helicopter in one shot.
Proceed through "The Root Of All Evil" until Psycho opens the elevator door. Enter the shaft and the elevator cables will break. Step back outside to encounter a CELL patrol.

Climb on some rubble and jump up to reach a difficult to see ledge. Pull yourself up to enter the ruins. Turn around, then keep jumping up from one level to the next until you reach the top. Notice the broken wall with the floor missing in the corner ahead. Jump into the alcove to the right of the hole to find a glowing suitcase on the ground. Open it to get a ketchup packet fountain.
