Make sure you have Corey & Sven. Let Corey stay on the stairs. Let Sven go down because
he will do mostly of
the physical ground work around to help Corey reach that door. As Sven, smash
the crates underneath the stairs until you get a FIRST-AID KIT ϴ. Seize
the tall stack of boxes you see in such a way that it's partly underneath the
part of stairs with broken railings. Switch to Corey and let him climb down
the top of this stack. Switch to Sven and have him drag the stack to the right
against the tall shelves. (Haha! I find their dialogue in this area
hilarious.) Switch to Corey and let him jump so he will hang on the shelf.
Jump sideways and keep going to his right until he reaches an end. Then, let
go. Corey will hang on the lower ridge of the shelf. Keep moving right until
you're on the edge of a shelf perpendicular to the shelf where you climbed
down to its lower ridge. Jump sideways to the left. On this shelf, go up. Pull
the lever against the wall so the ladder beside it will slide down. That way,
when you fall down in the succeeding climbs, you can go back at that spot.
Now, go up another shelf and take the SHOTGUN SHELLS. Then, go up another.
Switch to Sven. Go to the other side of the area and look for another tall
stack of boxes near the garage door. Drag this beside the shelf where Corey's
at. Switch to Corey and climb down this stack. Switch to Sven. Have him drag
the stack all the way to the other side, across another shelf. Take an ENERGY
DRINK between this shelf and the forklift. Switch to Corey and climb up the
shelf. You will see a flower here but you can't save yet because Corey and
Sven are still apart. Head towards the elevator and take it down one level
using the control on the corner. Switch to Sven and make your way below the
elevator. There are crates nearby and one of them has a FIRST-AID KIT ϴ.
Switch to Corey and have him lift Sven up. Both of these characters should be
together on the same platform before you can save on the flower. SAVE because
a boss battle is coming up. When you're done, enter the door for a cutscene.
