stage elevator. Now proceed ahead and once again to the R - there's
another ceiling grate and a strange wall on the right of it. Smash
the wall with guitar again and pick up metal brace. Ignore the
crate for now.

Now search the sewer for the blue "ACCESS" sign. Use brace on it -
this opens a door just around the corner. Enter the Saul's secret
lab.

Remove the weird poster and climb inside (use hole). Pick up axe
and exit. Return to the crate and pick the lock with the axe. Use
crate to get the suit. Return to Saul's lab and use suit on microwave
device (inside hole). Now go to "ACCESS" sign ang get the metal
brace back. Return to elevator and use it on doors, then use doors...

GAME SUCCESSFULLY OVER!

Enjoy the finishing animation (I couldn't, "thanks" to the miracles of
CD-rip :) ).
