This entire level is pretty
much one big fight with Sophia. Try to keep under cover
except for those brief moments when she has to recharge her
deadly energy bolts.
You start in the office and the battle begins when you near
the end of the hall. Run for the ramp then pull up and turn.
Ignore the monkey swing and just do a running jump and grab
to clear the gap. Pull up onto the pillar then pull up above
the monkey swing.
If you look away from Sophia you should spot a metal box and
if you look over the edge you should spot this level's only
secret. Back off and hang from the wall then drop and grab
onto the next ledge and pull up into the alcove to claim the
items and register Secret #1. When you are ready to get back
into battle, hang and drop off to the floor below.
Climb back to the ledge with the metal box and find the
catwalk leading away from the secret area. Follow it to a
button and press it. Do a roll and run back quickly to avoid
incoming fire from above. You should now find an open door
to the ledge above. Pull yourself up to the ledge and head
along the catwalk to the ladder. Wait at the bottom of the
ladder for the sound of Sophia recharging her energy before
trying to climb the ladder. At the top, climb into the space
to the right and get the Medkit if it's safe. Crawl out then
get on top of the crawlspace.
Run along this upper catwalk and do a running jump to grab
the far ledge. Climb up and move forward to the fuse box on
the wall. Put a few bullets into the box to finish off
Sophia once and for all. One of the four relics is visible
across the way, but your immediate path is pulsing with
electricity. Return across the upper catwalk to the
crawlspace and make the small jump across the street. Watch
out for electrified areas and pull up onto the tall wooden
box then over to the next box. Climb over the box to the
right of the relic to find the main power switch. Push it to
kill the power then safely claim your artifact. That's it -
I hope you enjoyed your stay in London.
