Under the Frontline

Proceed along the right wall to avoid detection.

Look for a lit pile of debris along the right wall.

Locate a helmet on top of a pipe or beam.

Turn left and search the rubble for a skeletal hand holding +3 BULLETS. Grabbing these bullets grants you a Moral Point. (Note: You find +2 BULLETS instead of +3 for this specific moral point.)

About halfway across the area, you will encounter a guard with a spotlight watching the ground on the right side.

Once past the spotlight, move to the left wall and disarm the trap.

Move past this trap and go right towards the rubble, then proceed to the right wall to disarm another trap.

Turn left and move towards the glowing mushroom patch.

Go to the right and disarm the trap.

Pass this trap and go to the left wall to disarm another trap.

A final trap is located in front of the glowing pipe.

Enter the glowing pipe.

Climb the ladder on the right side of the wall.
