Tips For Deck 11
This is the level where you're almost completely in the dark. There are two ways you can attemt this one.
(1)The boring way - you can use the laser to guide yourself around the deck and guessing at where the doors are. Or...
(2)The exciting way - the deck lift is in the bottom right-hand corner. So my advise is RUN FOR IT and hope you get lucky - I did !
Walk Through Walls
