Bathhouse: Finding the bombs
After going through the gate when chasing Shetland, the 1st bomb
is directly to the left of the gate that you enter. Go left through
a little crevice and you should see a red light flashing. Go to it
and disarm it. When you do that, one of Shetland's gaurds will walk
up the stairs. Kill him. To get to the 2nd bomb, go up the
stairs. Turn left then turn right and look straight ahead. You
should see another red flashing light down below the walkway. Hop
over the ledge of the railing and disarm the 2nd bomb. When you
are done disarming the bomb, jump on to the railing and pull
yourself up. Two guards will be to your left, walking on the
walkway. They will probably hear you; get ready to kill them. It is
fairly difficult to kill them without losing a lot of life, or at
least dying. After you kill them, go down the walkway to the back
wall. About halfway you will see another red flashing light. Jump
across the little gap and disarm it. A guard will come through the
back door right when you disarm the bomb. Kill him, then go through
the door and meet Shetland. You will then have to make a critical
choice; note: pull the trigger. It would be a good idea to quicksave
the game whenever you disarm and kill the guards.
