Enter the north western cottage.

This Super SS behind the mirror is a challenge. As well as the guard. Look out also for the guard hiding in the niche along the corridor.

With your newly acquired plasma gun finish off this Super Officer in the bedroom, and the guard coming in from the veranda. Now you also have a missile launcher.

Go through here and get the cross in the veranda.

Bring down the enemies in this room and take the first death chalice. You need two more crosses to get through that passage.

Locate this secret door.

Find a cross here...

...and here. Watch out for that bomb.

Continue.
